brake light problem

[riverratba]

when my lights are on my left tail light is dimmer then the right. when i back up and hit my brakes the backup light goes dim and sometimes completely out, as soon as i let off the brake the backup light gets brighter but not as bright as the passenger side light. any help would be appreciated!

Check all the grounds especially on the rear lighting harness.

thanks steelheadz, i'll do that. seems like i have a problem with one light or the other every time it rains. my signal lights act up every time it rains. soon as it drys up they work fine

Maybe your covers are kinda loose and water may be getting in. Have you checked to make sure the bulb isn't loose.

Here's the pinout's on the Reverse lamp switch and brake switch. I also found the schematic diagrams related to what you need as reference. I hope this helps.


Note: Automatic transmission uses the TRS(trans. Range sensor) to turn on the backup lamps.
