No stop light in BUMPER One side ONLY??

H2 SUV:

Need some help here..Only one Brake light is not working in the rear bumper lights. All other 3 brake lights work fine. Also all runnign taillights in all four lamps assemblies work as well.

I switched the light sockets,bulbs, etc.

Any ideas?

Bad trailer harness? (looks ok), any specific fuses for one side stop lamps?

thanks!!

Your talking about the lower bumper lights, not the uppers in the body? If so I believe the trailer plug is the source that feeds both bumper lights. I just bought that harness to add the lower lights to my bumper.

How about you stick a volt meter in the socket? You only have 3' of wire you issue could be in.

yes correct the lower bumper lights. Should I disconnect the trailer plug harness and check for continuity, etc?

I dont have the harness in front of me, but i dont think there are any disconnect points in it. The feed plugs into the trailer plug and the rear lights are hardwired into that. You can lookup the pinout at the trailer plug and check for continuity between that and your light plug.

Just had this problem with my truck, the running lamp in my left lower bumper light was working but not the brake/signal..... thought the second element in the bulb was bad, pulled it and it looked fine, replaced it anyway and still didnt work, tried another bulb and nothing. Took it into the dealer (Im under warranty still) and they informed me that the harness had a short in it and replaced it.... working fine now.

wether its a short or open circuit, it can still be easily detected w/ a volt/ohm meter. Probably take you longer to google the trailer harness pin out wiring than actually diagnosing it. Anyone should be able to do this if they wanted to save a few bucks.
