Wondering if there are any "known" problems with the hazard lights on the coaches. My rear lights don't flash with the hazards on and I am at a loss as to why! I can't seem to find any problems with the wiring anywhere.Has anyone else run into this before?

All the lights function normally except the rears do not flash when the hazard button is depressed. Any ideas as to why?

*Note* ....The factory cruise has been removed (Including the wires to the break switch)if that makes a difference.

Paul,

Do the Brake Lights Work??
Please check that as soon as practical if you have not already.

On most vehicles with an 1157 bulb, the 4-way just powers up the brake light circuit.

If the brake lights work, the problem is in the column area.

Check the long, flat multi-connector on the steering column. I had a similar problem. and it ended up being a loose connection at that location.

If the front flashers work, it shouldn't be the flasher unit.

Do be sure that your brake light work as well!

That's just it,the brake lights do work and so do the rear blinkers and side lights. The front and rears all run through the same blinker relay. I took the column switch out and cleaned all the connections but I still have no rear hazards (the only thing that doesn't work). Beginning to wondering if someone replaced the switch with the wrong one at some point and never noticed the hazards didn't work.

The hazards sometimes use a different flasher module then the regular turn signals. dig around for that under the dash and check for a bad flasher or broken wire. It is possible that an over load from trailer lighting burned the flasher out. a quick test is to swap it.

Ok, went out and checked a few things.The rear side markers DON"T flash when the rear tail light blinkers do.Is this the same on everyone's coach? If not it could indicate that the rear lights on mine are wired wrong.
Oh and according to my wiring Dia. there should be only one flasher relay ( which I replaced already because the other one was on the fritz )for all the lights.However i will check to see if there is another one hidden up there somewhere.Who knows what the previous owners did as they did tow a car around with it.

The rear side markers do not flash.

The 4 way flasher wiring is all in the steering column. Replace the turn signal switch assembly and it will come with the 4 way switch also. I replaced mine in the parking lot at AutoZone. It was about $30.00. AZ will loan you the steering wheel puller that is required. If you are afraid to do it in the lot, take it home and remove the wheel there. AZ will loan you the puller for a deposit which you will get back when you return it.
