I have a 1999 Jeep Grand Cherokee and when I step on the brakes the left rear tail light go's out completly. The right rear tail light works as it shoud. I changed all 3 bulbs in the left tail light but this didnt help. Has anyone had this problem. I checked this with a meter. When I hit the brakes I loose the 12 volts.

I have the same problem on my 99 GC Laredo. When the lights are on and I brake the left tail light goes out completely. When the lights are off and I brake the right tail light goes out completely. Any suggestions?
