I have a odd story regarding my turn signals ('77 Palm Beach)
Last time we used the coach the indicators just stopped working;
tried new electronic flasher, no help. All fuses checked out.
Gene Fisher said to unplug the flasher to get the brake lights working again;
that worked, but still not turn lights.
The hazard flasher and lights work fine. Parking lights are OK too.
Now it seems the turn lights are working some of the time. Not reliably.
My flasher is a 2 wire system, purple on 1 and pink with a black strip on
the other wire.
Where might I find the grounds to check them?
Any other ideas what I could check? Need to get the coach out
before summer is over!

If you have an AARP card you do not need to use turn signals, except to leave them on all the time. Preferably indicating a turn in the opposite direction from your next anticipated turn. <GRIN> (this is from someone who has been mortified to find he has had his turn signal on for 10+ miles.)

All my lights were acting weird when I bought the coach. Somewhere on here recommended changing the headlight switch. Easy change and only about 12 bucks at the local auto parts store. Don't have the number handy but i think it is in the parts index. Fixed all my problems.
Good Luck

Sir: You might look at the multy wire plug-in on top of the steering column near the floor. Sometimes the switch isnt plugged in good .

Do you mean down low, near the floor on the steering column?
Mine has 3 plastic connectors...
first one has 2 purple wires
second one has light green, a dark green and a purple
third one has brown, black and blue wires
I can't seem to find my manuals. What are these 3 connectors
doing?
Thanks!

And also remember that the turn signal lights and the side marker lights are on the same wire. Separate wire on each side. Installed in series. They then ground to the chassis. This is why LEDs require a different wire route to work.
Alan Henderson's large scale wiring diagram will help you follow the wiring, or help with the clues to where all the electrons are going. No telling what your P.O. did or intended when you get into it.
Highly recommend the wiring diagram.

Is this replacement connector a direct match?
Are the color codes the same as ours?

Sir: Parts ain`t what they use to be. I have found that yes most is the same wire colors in order but some that have been flipped? Don`t really know why but I think the tilt columns colors are flipped in the plug?? The Link I sent from autozone is for a $19 switch with cornering lights for 76 Toro. Only difference is it has 2 extra wires on the end of the plug that goes to cornering lights which can be installed. The $39 dollar one does not have cornering lights. If the wires are flipped just use a small plastic wire tie end to release the wires from the connector and put where the ones are on your original.

If both stop lights work when the directional is turned on I would suspect a problem with the directional switch,

OK,
First off, thanks everyone for the replies.
Took a good look at the flat multi-pin connector
high up on the steering column.
It seemed to be seated correctly but after close inspection
I saw a small amount of corrosion down inside the female
half of the connector.
Sprayed some electronic cleaner ('2-26' ?) down inside it.
Put everything back together and so far, so good.
Guess we'll see if this is a lasting fix.

A word of warning on this switch. There were two slightly different connectors used. The pins are the same but the plastic connecter on one is slightly longer and they will not plug together. So before you pull the old one out try the new connecto to see if it will match what you have on the lower steering column. If the new one you have does not match, you have three options.
1. is to remove the pins from reuse the old plastic on the new cable.
2. is to go shopping for a different switch assembly.
3. I did see once an adapter cable packed in one of the switch boxes that could be used.
It has been 10 years ago so I do not remember much more about it because mine fit right out of the box.
A hint on installing this cable / switch asm. is to cut the old connector off before pulling the old cable out. A second hint is to tape a heavy sting to the cable a the bottom and pull the string in the column as you pull the old one out. Now you have a string to pull the new cable through the steering column.
Even thou Gene posted a link to this information, I will post it directly here. Some of it is redundant with the above information.
************************************
TURN SIGNAL SWITCH
AutoZone part number SW326 or SW327.
This is a very common turn signal switch used by GM on vehicles of that era. It is not GMC motorhome specific.
These are made by Wells. The difference in the two numbers is that one also included a set of contacts for cornering lights. The cornering lights are actually a separate connector that plugs into the same switch that you do not have to use. Wells is actually the manufacturer of the switch for Delco (GM) . My Wells switch came with the Delco inscription on the plastic molding.
The problem you will run into is there was two different plugs used on the connector depending on the year the coach was made. One is slightly longer and will not plug in. These part numbers from Autozone come with an adapter to fit both cable connector styles. MAKE SURE THERE IS AN ADAPTER IN THE BOX WHEN YOU BUY IT. You may need it.
If yours is the opposite plug type and you do not want to use the adapter, you can remove the pins from the old plastic plug and insert the new cable pins into it. The pins are the same only the plastic housing is different.

Ken,
So it appears from the photos on Autozones web site
that the turn switch and the flat multi-pin connectors
all come as an assembly.
Is that correct?
In my case, I wanted to avoid removing the steering wheel
to replace the switch, I just cleaned up and sprayed
the contacts on the flat connector.
So far so good. Sure hope it lasts.

You are correct. It is not a difficult job. I took less than 1/2 hour doing it in AutoZone's parking lot using their loaner steering wheel puller. Tape the connector flat against the cable and attach the string you pulled through the steering column. Then simply pull on the string while you feed the cable in from the top.

Steve, I have been down that road with you. Now I have buzzers in the GMC and the Vdub. Really ticks me off to get behind someone with a left blinker going. Don't know just what their plan is. Wife hates my buzzers, grandkids hate my buzzers, but I no longer have to worry about running down the road with my left blinker on.
Sorry to get off topic but Steve's note brought a smile to my face.
Life is good when you find your "fix" right here among friends. Sounds like all lights are blinking again.
