I have a 2000 Jeep Grand Cherokee Laredo with a 6cyl engine. Recently, a friend of mine told my my rear brake light was burned out so I bought a new lamp and replaced it. It was then that I noticed that the lamp wasn't actually burned and the same problems persisted with the new lamp (and another second new lamp). Here's what happens....
When the parking lights are on, both tail lights come on fine, both with the same intensity. If the tail lights are off and you press the break pedal, both brake lights work (although the one on the driver side is slightly dimmer than the other one). If the parking lights/tail lights are on and you depress the break pedal, the lamp on the driver side goes off completely. The one on the passenger side works fine.
I checked all fuses and relays (could not find a relay for the break lights, only one for the tail/parking lights). I could not find any ground either....sometimes a bad ground can do freaky things. Any suggestions or someone experienceing a similar problem? Thanks!
Regards, Dave.
