Hi all: few things I could use advice on, appreciate it.

1. dash blower fan seems not to do anything???? makes ride home to north be
colder. as RV heater not working.

2. drivers feet there is much outside cold air coming in. suggestions for
temp fix for ride north?

3. I have a nice Wilson CB antenna magnet mount base maybe 4-5 inches in
diameter. suggestions to attach it to roof? I thought to glue a stainless
plate or something to roof. maybe glue or screw plate to AC unit? not sure
about screwing into roof itself.

4. I have no horn, I bought a air horn kit at harbor freight and have it
with me buddy and I might try to install it today after timing and
alternator stuff.

thanks all. hope we have faster easier drive trip home north bound thursday
fri and saturday.

thanks

I upload pictures when arrive home and plan to be a bit more active with my
GMC etc...

Mike,
1 Was it working on the trip down? Have you checked the fuses?

2 Was this working on your trip down? Check your coolant level -- low level may reduce the amount of hot-coolant getting to the heater core. Is there a manual valve in-line to your heater core?

3 A mirror mount antenna may be easier to hook up.

4 A wire and toggle switch to the horns may be faster to install as a temp measure -- but fix the heat first!

Please have it well prepared for your trip back north -- the forecast is for cold temps here over the weekend -- too cold to enjoy a Black List call-out!

1. dash blower fan seems not to do anything???? makes ride home to north be colder. as RV heater not working.
____________________________________________________________

You may be experiencing what we all have. IF THE FAN MOTOR IS RUNNING, it is the poor air ducts that prevents good ventilation. IS YOUR FAN RUNNING?

=======================
2. drivers feet there is much outside cold air coming in. suggestions for temp fix for ride north?
_____________________________________________________________

If you look at your GMC from the front down the sides, see if the body panels next to the driver and Passenger kinda poooch out, like a chipmunks cheeks. This is the body panel come loose and pulled out from the air flow of the vehicle.

When this happens, air comes in from under the floor around the panel and into the cab.

-- or

There might be a PO inspired fix to the ventilation that is allowing outside air to come in from the outside from under the dash. Been there, done that

========================

3. I have a nice Wilson CB antenna magnet mount base maybe 4-5 inches in diameter. suggestions to attach it to roof? I thought to glue a stainless plate or something to roof. maybe glue or screw plate to AC unit? not sure about screwing into roof itself.
___________________________________________________

Don't use Stainless Steel, the magnet won't hold onto it. Steel would let the magnet hold on but might be better off with a mirror mount.
=========================

4. I have no horn, I bought a air horn kit at harbor freight and have it with me buddy and I might try to install it today after timing and alternator stuff.
____________________________________________________

If you have a solenoid, you might be able to use the GMC air tank to supply the air.
Use a relay that picks up by the horn ring, using the relay contacts to power the solenoid.

On the heater fan. Does it not work only in the highest speed?
Or does it not work at all positions?

Lots of thinkgs can cause this. We need more information.

It could be a blown fuse, a bad motor, or and bad fan relay.

On the horns. Again three things. The horn button contact in the steering wheel, bad horn relay, or bad horns.

Unplug the horns, take a jumper wire and attach one end to either the top or bottom post of the isolator. take the other end and touch the horn wiring contact. If it honks the horn is good and it is time to start looking at the horn relay.

With the engine not running. Stand close to the relay and listen while someone else pushes on the horn button. If you can hear or feel click, then the circuit to the steering wheel is good and you probably have burned cable connection at the horn relay or a bad relay. The last time I needed a horn relay AZ had them in stock.

You can also check fan motor by unplugging it and jumping it direct from
battery.
I don't know how to check fan relay Ken will need to help you here.
On the heat problem, the vacuum operated shut off might be broken or stuck.
Check the vacuum shutoff in heater hose under the hood in front of the HVAC
unit.
Look for holes in floor by drivers feet. Wires come through a hole there and
the hole may have lost its insulation putty. If this is your problem it can
be sealed
with duct tape to get you home. Enjoy your warm tempatures in Houston. It
gets colder as you come north.

Heater blower motor ground was a frequent problem for me; need to ensure
there's a good connection from the black lead to the body -- it can't ground
through the plastic fan enclosure.

For #3:
In our coach is a narrow section of ceiling, just behind the front
headliner. If you have that, you can remove it and glue a whopping big
speaker magnet to the underside of the roof.
Check for proper magnetic polarity (the speaker magnet attracts the
magnetic antenna base), so they will be attractive (instead of repulsive)
when installed. (snicker, giggle, etc.)
The magnet was someone else's original suggestion, I just borrowed the
idea, cause it sounded good.
Whoever originally used the idea said it worked well for him.

Stainless isn't as magnetic as regular steel, because of the other things
added to the steel to make it stainless.

It's a little later in the day, now, and someone else has probably
suggested this.

"gluing" a large magnet to the SMA body cap may attach the antenna by magnetic attraction, but will not provide enough ground plane for the mag mount antenna to work properly. I would suggest that you purchase a mirror mount and an antenna that does not rely on the "mirror image" of the ground plane to work properly. They are available. The trucker "dual mount mirror antennas" will not provide any additional range or signal strength to your CB. Just looks cool.

For the blower fan, if it does not work at high speed only, the relay on the firewall is shot. Replace it with a new one, perhaps at a higher amperage rating than the OEM. This replay (depending upon A/C system) placing 12v from the alternator to the blower fan, when the engine is running. If the blower fan does not work at all, look to an additional grounding wire from the blower fan to the firewall (as Ken suggests). Pulling the plug that goes into the blower box and cleaning it may also help. Put anti-ox on the plug ends when you put the plug back together.

The location behind (aft of) that narrow ceiling partition on my coach is
in the aluminum portion of the roof, so it provides plenty of metal for
the ground plane.

While not really the best looking solution, when needing to travel in the winter, I filled every crack and crevice in the firewall with "Great Stuff." This includes both under the hoods and behind and over the front inner wheel wells. I even used up the last of the can sealing the rear wheel wells. (It doesn't "keep" very well.)

It has held a LOT better, and stayed more flexible, than I expected. I did paint the foam in the wheel wells black after it cured. Just brush off any loose dirt and stuff before applying.

A good place to stick a magnetic CB antenna is on the refer vent. (If it is metal.) It provides a ground plane and a place to route the wire into the coach. The down side is the longer coax needed.

Mike - on the fan: Wiggle the blower switch a lot when you move it (left,right). Really work it. Tom Hampton amazed me when he got my fan working just by proving the switch was not making good contact. I hope this helps. Have a safe trip home.

For fan quick check exercise the connections at the fan relays (timer relay if you have one and HI blower relay) and at the fan resistor. These love to become green and corroded and/or melt down from resistance heating.
Cold air by feet---without the fan running you won't have postive air pressure in the cabin and all leaks will be more pronounced. For the leak by the feet a lot of coaches have the spread separation between the firewall and the side body panel = air leak. I used THRU THE ROOF clear flashing sealant for roofs on mine with a paint brush reaching in there as far a possible and painting the seam. The 30+ year old sparse factory tar job has long given up the ghost.

Good point. I forgot that one.

This really should not be difficult with a VOM on even a test light.

Every one needs cheap VOM if you are working on a GMC. Harbor Freight has them for $3 to $7 depending if they are on sale or not.

Tom,

You can also mount the magnet to the aluminum portion of the roof. They work well there and you have some ground plane.

As you know it is impossible to get a proper ground plane because of the real estate required for CB. So any ground plane is better than nothing. It really does not matter much to CB users as they only want to you use it for very short distances anyway.

If you have a roof rack. U-bolt yourself a piece of flat metal to it and set the mag mount on top of it. The size of the metal (steel) depends on diameter of the base of the mag mount antenna. For big bases use an electrical box cover. On small bases a short steel strip held in place with a couple of stainless hose clamps will do. I have a 1" wide one up there that I stick 2 meter, WiFi, and GPS antennas on. Be careful using u-bolts as you can crush that roof rack aluminum tube easily.

The trucker "dual mount mirror antennas" will not provide any additional range or signal strength to your CB. Just looks cool.
_______________________________________________________

Is this correct?

The dual antennii are Top loaded and usually increase range at least 50% better and receive improves also.

Used to talk to a dual antennii on a car and could talk to him many miles a way as they drove home in the evening.

yea right.

Take a fluorescent lamp and run it up and down perpendicular to any antenna while it is transmitting. Then tell me that same story again. You might not be able to do this on only 3.5 watts out on CB. To you try it on CB use a very small / low wattage fluorescent.

Loading is an attempt to make an antenna look electrically longer that it really is. Loading is used to match the antenna to the transmitter, not amplify the signal.

For ground wave, which CB is when the skip (sky wave) is not active, it still comes down to line of sight, radiation pattern and a little bit on power for communications distance between the two stations.

Years ago I really missed out on the CB antenna business. I never realized that CBers would be gullible enough to would want multiple antennas or pet rocks.

If two antennas are better than one, then why not go to 4 or 6 antennas for further improvement. Please come back to me when you want to buy those antennas and I'll sell them to you.

The best mobile antenna on CB at 27mhz. is a 102" whip mounted mounted in the middle of a 204" diameter metallic circle. A center fed 204" whip would also work as well. Just watch out for the underpasses. Anything else is a compromise. Obviously neither is practical on any highway mobile vehicle. So we get all kinds of loaded antenna designs to shorten antennas to a practical length for a vehicle. Top loading (top hats) is also used on AM radio towers to reduce the height of the tower required.

If you open the passenger side engine hatch, you will see a round horizontal motor on the right hand side of the opening. You will also see a wire with a round plug on it--make sure that is making good contact.That plug will affect all blower speeds. If you open the driver side hatch, you will see a rectangular plug on the lower side of the rectangular air box. You may want to pull that off and see if the contacts look good. That connector controls all blower speeds other than high. When you checked the high blower speed, was the engine running?(the engine needs to be on for the high blower relay to work). The fuse in the fuse block inside controls all blower speeds except high.
