Grand Cherokee - Tail Lights Not Working

So I started with no tail lights and 1 missing brake light.

All other lights (interior, front, turn signals) worked fine. I changed bulbs - still no luck. Changed fuses - no luck. Read a prior post about the adjusting the chrome pieces on the metal assembly.. tried it and now the brake lights both work but not the tail lights.

About an hour after brake light fixed, the right turn signal started blinking fast.

Any ideas what can cause the faulty tail lights and quick turn signal?

The sockets and tail lamp assemblies have issues. After cleaning connections and fixing mine several times, I finally bought LED lights on Ebay.

Before you buy new housings and sockets though, I would pull out a voltmeter, unplug the wiring harness, and start testing for power at the harness. If you are getting power back there for tail lights, brake lights, turn signals, you have a good ground...time to replace the housings.

agreed. the sockets suck. and are expensive to buy new. I went to the salvage yard to replace mine.

I was having a similar issue, and after testing enough that I was satisfied the housing itself was not the culprit, I ordered these. (http://www.amazon.com/Dorman-923-034-Tail-Lamp-Socket/dp/B000TYSBYY/ref=sr_1_fkmr0_1?ie=UTF8&qid=1328048444&sr=8-1-fkmr0). At ~5 bucks a pop, I bought 6 replacements just so I don't have to deal with the BS anymore. I had gotten pulled over 3 times for having a tail light out, 2 of those times the cop let me get out and show him how to fix it quickly, (I had gotten it down to a <3 minute process).
