95 yukon keeps blowing park lamp fuse

[CandyMan337]

Hi guys. I have a 95 yukon, & just the other day it it blew the park lamp fuse on the dash. As a result my tail lights & dash lights won't work. Brake lights, turn signals, & everything else work fine. I changed the fuse & it works until I start the truck then it blows again. I checked the circuit boards on the tail lights & they're fine so are the bulbs. I need help. What could it be?? Thx ahead of time for any help.!!

it is a short circuit to ground, you'll need to trace the park lamps circuit and check all related wiring for damage causing the problem. Any recent repairs/mods that could have caused this? Radio/deck installations are a common cause...

Yes I just put my radio back in my truck. It was fine before I but it back in. I also had my motor & trans. rebuilt & upgraded. I'm still working out all the lil bugs with that to. Thanks for the help.

I had a similar issue turned out to be a bad headlight switch

I had an extra headlight switch, so I changed it. But still blowing fuses. I even changed the circuit boards for the tail lights. Still blowing fuses. The only difference is it dosent blow right away. But it blows at random.

What failed in my switch was the rehostat any time I touched it boom fuse blew
