Okay, hi good folks! Regarding my chevrolet s10 2.2 2002, the taillights are not working, netiher left or right (brakes, headlight and indicators works). Let me get straight to the already done diagnostics, fuse 10,34 if I remember correctly is good ( so is every fuse as i tested them all). No power to tail light socket, but power to break light socket when brakes are applied obviously. Power to both indicators aswell. I have checked for good ground and redone the ground.

Moving foward I can not see any damages in the wire harness. Now to the headlight switch, everything looks fine on this one, no corrosion. I tried a jumping wire from orange ( live wire ) to LTBLU wire, still no taillights. Measuring on the pins in the fuse holder on DTL i get no power outcome, neither do I get any power measuring when headlight switch is engaged. 0.0 volts on both fuse 10 and 34.

This my good friends begs the question, is it a fault inside the fusebox, bad connection from batt to fuse OR might it mabey be a fauly relay? In that case wich relay activates power to DTL, park light etc? Ideas?

Hi my friend I have a 1995 s10 and bought it about a month back. I was having trouble with my tailights. Read a post online about a wire harness on driver's side near rear bumper. Crawled under there and found a wire black that was clean snipped. It was a grounding wire back there. Repaired it and tailights are working. Please let me know what you find. Good luck.

Yes hello thanks for your answer sir! Unfourtantley for me, I also read about this problem with 4 grounds going into a clipper and to chassi via 1 ground. I redid this ground and tested but no, still no tail lights unfourtantley! I will keep this updated!

If you have no power at the 20A fuse under the hood labeled PARK LP, you may may a problem in the fuse box. That fuse should be hot at all times and is fed by the IGN A fuse. If the IGN A fuse was blown you would also be missing power on many other fuses that are on the same bank as the park light fuse, such as the 60 amp ABS fuse, the 20 amp HAZ LP fuse, as well as others.

Try your head light switch itself. Get one from the yard cheap of cheap on fleabay

One novel idea would be to try 2 new bulbs. I've seen more than once where that was the problem. I chased a turn signal problem on an 02 Blazer for 1/2 a day until I figured out 3 bulbs were bad.

Okey update, today while starting the car the taillight magically appeared. I think its due to the weather as it's been in the negative Celcius. Therefore I think as someone previously said, its either the switch itself or a relay that somehow is being affected by the cold, nevetheless a quite strange problem. I'll keep you updated, and thanks for lots of replys
