I'm having a brake light problem...

[DGC3]

Any help is much appreciated.

It seems as though every other light is in full working order except the brake lights. This is on an '88 IH S1700 Thomas body. Would this be a fuse, or a bad connection? Or maybe something came unplugged?? Not sure...

I would go a take the lights out and sand all of the connections, many of my lights were irratic until I cleaned up their connection to ground.

If you have air brakes there is a pressure sensing switch as well as the regular fuse, wiring, etc. Like Steve said...start with the easy stuff like getting rid of corrosion and bad bulbs.

the brake light switch on my skoolie went bad. I have hydraulic brakes. if you lay on your back and look under the dash at the brake pedal, you'll find the switch....if you have hydraulic brakes. You might even find 2 of them. One for the brakes, and a separate one for the electric/hydraulic backup brake booster.
