I have a 97 V8 w/trailer tow. Hook up the rig Sat morning and....No Running lites, no brake or turn signal lites. Lights on the truck work fine. I can operate all the trailer lights with a seperate power source, so the trailer is A-OK. I also buzzed out the round to 4 in line adapter - OK.
Yes the fuses are ok....But. Here's where I got confused. Fuse # 3 and 7 are the left and Rt stop and turn fuses and they are OK. Owners manual call out a Fuse # 30 for the trailer lites. There is only One contact in that position (not two) Fuse position not used.
By the way.... I checked EVERY fuse in the panel by the door..all good. As are the fuses in the power distribution box.
Anyone out there have a 97 and can verify which fuses and/or relays control the trailer lites. I think a relay has died but cannot locate it. Truck has cost me one nice day on the water and don't want to miss another.
As always any help is greatly appreciated.
