Headlight problem need help ASAP

[Sullen]

I've searched and searched and searched and had no luck. I have a 2002 Chevy Tahoe LS 2WD and my headlights have decided to do the craziest thing.

So when the headlights are on my LH low beam is fully lit, my RH low beam is only half lit (dim) now not only this, but the highbeams are also half lit (dim) with only the low beams on.



If i swap to high beams the same thing will happen only the high beam bulb will fully light up on the driver side and all other lights stay half lit (dim)




I've checked everything I can think to check headlamp switch, grounds, connections, fuses, relays, etc. the only thing I haven't checked is the turn signal switch, I just would like to have an idea as to what it is before I go throwing parts at it.


Anybody seen this before???

Bad ground?

Update: I have solved the problem for now, I ended up having to do some rigging but it all works for the time being, I just had to run a jumper wire from the driver side low beam (yellow wire) and splice into the passanger side low beam (yellow wire), it has fixed the problem and hopefully won't show its ugly face for a while.

Are they fused separately?

Since you jumped 12V over to the passenger side, that would lead me to believe that it is either a relay, fuse, or a break in the 12V wiring.

If you felt like figuring out what was wrong, you could undo your new connection and just meter for 12V, starting at the headlamp and working backwards. Also meter 86 and 30 on the relay. Eventually you will find your break.

I have the same issue. In addition when headlights are on my rhs turn signals flash rapidly as if a bulb is out, but all signal bulbs are functional. I have several other electrical gremlins as well (radio won't turn off when driver door opens at times, driver seat and side view mirrors readjust to random settings upon ignition turn off).

I had something similar at one point and I believe a fuse solved it.

The yellow wire is a ground, (if you ground the yellow wire on low beams 00-02, it gives 4 high lights on high beam, don't cut wire just tap into it) so I would check the grounds attached to the frame and body, or a broken wire from socket
