1996 MADP no brake lights disappearing tail lights

[DavidSmith17]

Where is the brake light switch located on a 1996 Mountain Aire? I don't have any brake lights and my tail lights are wacky. I have had 3 different RV mechanics look at it and they cant find anything. When my headlights are off then I have tail lights, but when I turn on my headlights the tail lights go off. I don't have any brake lights when ignition is on. Turn signals seem to be the only lights I have all the time. The last shop I had it at called Spartan with wiring questions but never got a call back. Anybody got any ideas?

1 assumption - they worked at one time. Was there anything added to the electrical just before this started? Otherwise I think it is a ground problem. I had some wacky stuff happen when I had the boat trailer hooked up and the ground was bad.

Welcome to the forum.
Have you looked around the brake pedal on top of arm of brake pedal you may see a switch with a plunger that drops down when you depress the brake pad.
Have you ever checked behind the brake lens and checked the wiring and lamp sockets on a metal bar with ground wiring and power wiring to lamps.
Everything may need to be cleaned up from corrosion on wiring and bar for lights. --Brochure --- Owners Guide 1997 Oldest we have.

The stop light switch is air operated and under the front hatch. The tail light issue sounds like the ICC blinker switch left of the steering wheel is causing the problem. When headlights are on and you push the momentary ICC blinker switch it shuts the tail lights off. When the headlights are off and you push the ICC blinker switch it turns the tail and marker lights on. Sounds like the switch might be holding in the on position.

This maybe causing your problem also.
