2007 Tail Lamp Problem

Hey ya'll. I have a 07 Grand Cherokee with a tail light issue, here is the run down.

Turn key to ON, everything works.
Crank ignition with Light Switch to A, ON, Running Lights, Tail Lamp on Drivers side FAILURE. No tail light, no brake light, no turn signal.
Turn Light Switch OFF, eventually brake light, and turn signal return.

Weird huh.

I was raised up a car guy so I have already checked fuses, relays, bulbs, wiring, voltage, ground. All good, even replaced the fuses and relay for the heck of it, swapped bulbs too. Same deal. I recently found on a random yahoo! thread where somebody had a similar problem and the call to fix this similar issue was replacing the Tail Lamp Socket. So, I pulled the assembly back apart to check and the contacts on the socket are all discolored, they aren't cooked or melted, just definitely some Arcing has been going on. I am getting a new socket on Monday to see if this fixes this problem, but if it doesn't, I am at a loss as to what to try next. Any thoughts? I am an old school car guy so if this is a circuit board or computer problem I won't even know where to start to look. Thanks for any help!

Your tail lights are slightly different then my 05. But I'm still pretty sure all functions are fused seperately: ie, running lights, brake lights, turn signals. They are also split left and right. So there are four to six fuses and relays total for your tails. So, if your left tail goes out completely I would tend to think it's the connection at the bulb or in the harness somewhere. If the contacts are discolored like you said that could very well be your problem. Hopefully the new socket clears up the issue. I would suggest you put a little dielectric grease in the socket befor installing the lamp, it'll help to prevent corrosion and arcing.

$20 freakin bucks for a tail lamp socket from Landers-McClarty Jeep here in Huntsville, AL. Nonstock, special order item only. What? Also needed ONE count em ONE single, solitary floor drain plug for my 2007 JK, also a nonstock, special order item, cost $15...I skipped it I was so pissed. What happened to decent parts houses and service shops that are worth a flip?

Hey all. Having the same problem. 2007 Grand Cherokee Laredo. When my headlights are OFF my left rear brake light and turn signal work just fine but when my headlights are ON that bulb is not working. I've checked out some other threads that dealt with '00 or '01 GC's but the housing for the lights is different on mine and doesn't have the contact points that seemed to be the problem with the older model. I just had my bumper replaced and am wondering if they jostled something out of place?? Help would be appreciated.

KeenKong,
when my new socket comes in I will let you know if it fixed it. If that ain't it I will have to check my wires I guess.

The verdict is in, my new tail lamp socket came in part #4857378-AA. And I now have fully functioning tail lights again. The guy at the parts department actually admitted it has been a long time running problem...go figure.

Had the exact same issue and sockets were the fix! (After three hours of a electric guy trying to diagnose. Wish I had seen this post!)
