How do you fix a brake light on your 2001 Grand Cherokee Limited that comes on when putting on the low or high beam lights but do not come on while braking at anytime although you put in new bulbs?

Answer 1

Fixed this problem yesterday myself with the help of another website. Below is the fix. Good luck. Web site is www.carsurvey.org I own a 2000 Jeep Grand Cherokee and I too had the same problem on the left tail light/brake light. Thanks to this website, I've regained my sanity (and stopped changing lightbulbs). Additionally, I was not going to pay for a part unless I absolutely had to, and I was able to repair the light with info from this website. In return, I thought I'd post how I did it. 1. Remove the tail light assembly. Most of you know how to remove the light assembly if you've changed bulbs, so I won't cover that. 2. disconnect the wiring harness by sliding the red locking clip to the side in order to press the side of the male connector and pull apart. 3. Once you've got the tail assembly away from the vehicle and on a bench, remove the light socket for the tail/brake light. You will see 3 silver contact points inside the black plastic ring. 2 are grouped together and there is one that is opposite of the 2. The one by itself is the ground; the other two are the contacts for the tail light and brake light. The problem lies with the ground connector. (BTW, I tested continuity with all lights and contacts including the turn signal and the reverse light to verify that the circuit board itself was good, and it was). 4. clean all contacts with a Q-Tip and some sort of contact cleaner - rubbing alcohol will work. 5. You should notice that the ground contact is depressed into the plastic and the plastic itelf is slightly warped down. I was able to use a small pair of needle nose pliers that have a 45 degree angle to press up on the contact from underneath using the opposite lip of the hole as leverage (very carefully). Once it had moved up a bit, I was able to wedge a mini-flathead screwdriver in between the metal contact and the plastic to force the contact up even further (again, very carefully). Once it looked even with the rest, gently reinsert the connector and test. Hope this helps...
