Brake lights/turn signals out
« on: June 28, 2011, 07:54:09 pm »
My brake/signal bulbs aren't working. Both.

Fuse is good
Bulbs good
Everything seems snug

I can disassemble the housing and remove the bulb, upon reassembly everything works fine. At some point it quits working again. Wiring looks okay, but I suspect the splice done by a PO for the trailer hookup. I'll chase that down tomorrow, any other ideas to look at while I do?

seams like you have the right ideal on what to check and you should find your problem

Check the grounds behind the lenses and clean the sockets.

I had screwy wiring and similar issues when I first got my truck. The trailer "wiring" was a bunch of e-tape and some wire nuts. I butt spliced the 3 wires together and it was all better, but one night all my tail lights went out because the ground splice came loose. If youd like I can snap pics of the splice so you can see which wires.

I checked over everything with no luck.  Finally pulled the bulbs again and noticed that one end of the filament in the pass side bulb was broken.  I guess moving it around when putting it back in made contact for a while.  New bulb and everything (driver's side too) works fine now.  No idea how that happened.  Still going to rewire the trailer pigtail this weekend.
