brake lights all messed up

I have a 99 limited and when headlights are on all marker lights work when I push the brakes back tail lights go out and high brake works ,no other brake lights come on. Also high brake light stays on dimmly. When head lights are off drivers side and high brake light work no pass side. Any help would be appreciated. Checked bulbs, and circuit boards. Maybe ground ,but where. All other lights work as they should, front that is.

Re: brake lights all messed up

Many times problems with the brake lights are caused by the sockets. The small copper coloured tabs must be bend outward a bit to solve this. I had once one brake light which every time was ok for a day or so after doing this, but then stopped working again. Then i bend a bit the opposite site in the light armature and all ok.
I never had the high brake light stay on dimm though, but try this first and lets see what it does.

On the older ones, wasn't there a ground on the drivers side taillight assembly that had the bad habit of becoming royally munged up?

Get a cheap volt/ohmmeter and measure from the outside of each socket to a known good chassis ground. You want zero ohms. Not even 0.5 ohm is good.
If you don't have a meter [get one, they pay for themselves at about $10] you can try using a heavy wire from the outside of the socket to chassis, but be careful so you don't let out any magic smoke.


BTW is there a constant, but not very loud, door buzzer sound?
I had a bulb in the CHMSL burn out, and the rear lights all went funny until I noticed and fixed it. The bulb sensor warning was on, but otherwise highly uninformative.

Re: brake lights all messed up

I would not expect a ground problem here, since the ground studs are used for other lamps as well and the ground will not change using headlights or not. Center brake light has the same ground stud as the left brake light.
I bet the problem is with the light sockets tabs, also since this happened to many others.
