So I'm chasing down a gremlin in a 92 F250 7.3 idi on the day I'm supposed to be leaving for a 10 day trip. Any advice appreciated. Here's the situation.
I got no brake lights but my turn signals work and the hazards work also. Additionally, if I apply the manual override brake for the brake controller when that is connected then the lights come on. I've replaced the multi-switch and checked all fuses. I ruled out that it is a ground since the turn signals and brake lights will still come on. I think it might be the brake light switch but I have already replaced that once so I was skeptical it was that at first. I'm off to but another and swap out but I'm not hopeful that will solve anything.
I recently installed the trailer brake controller. It worked at install but now that the lights are out it only operates if I push the manual override button to apply brakes. I'm not familiar with how that wiring ties in but I could see that being a fail point as well since it seems that it is getting it's brake pressure reading from the switch as well? It's a little over my head though so any insight is welcome.
Thanks!
