I have an 02 Dodge Ram 1500 3.7 ltr. manual trans. I got in my truck and started it one afternoon and the speedometer pegged all the way to zero with a quickness and went back to zero and hasn’t moved since,my ABS,airbag lights came on, my brake light stayed on after releasing the brake, the A/C won’t switch on yet the fan works, also the cruse control won’t work. I’ve checked the fuses and the relays in the fuse box and they seem to be O.K.

I have an 02 Dodge Caravan and have had similar problems with airbag lights coming on and off, brake and ABS warning lights, etc. My mechanic put in a new clock spring assembly which at least took care of the airbag lights. I’m still trying to figure out the rest!
