I have a 1988 GMC 3500 truck, all the lights and the radio stopped working when I hitched up my horse trailer. Same trailer works fine on my 99 dodge, same pulg to trailer. What happened?


You blew a fuse. Check the in cab and engine compartment fuse box and replace burnt fuses. It's possible that you have too many lights on the trailer. This would cause a multiple amp draw on the truck pulling more power than the typical 10-25amp fuse supplied for trailers.

2000 gmc sierra dash lights and running lights remain on after


It seems you have a sort circuit in the wiring or the switch......

normally you have 2 types of shorts, 1 is to earth and this causes the fuse to blow, indicating a fault and preventing a fire.

The second one is a short to power, where the circuit remains on, despite the switch being turned off.

I would suggest that the park light switch is shorting out.

If you are not familiar with electronics, I would prefer you seek an auto electrician to do the job.
