I have a 2000 blazer zr2, the headlights are automatic but they wont come on. even when I manually turn them on with headlight switch they still don't come on. I checked the fuse and it was good. any ideas of what the hell it could be? GotMud?
No tail lights either?
Bad switch? Faulty ground?
Check the relay...
have tail lights, break lights, turn signals. noticed today they came on when I put it in gear, and while in gear I turned headlight switch on and they turned off. I will check again when it gets dark.
Where's the relay at?
I believe its under the hood with the rest of the relays/ maxi fuses.... if the lights are going off when you turn the switch to on, it sounds like you got a short somewhere....id start with the switch...
High beams could be on too and have a short there. Been there before. No headlights, clicked the high beams off, and I had low beams.
High beams don't work either. Could it be a short in the multi-function switch?
Yes...its most likely where it is or sounds like to me
I know its already jacked up. the multi function switch that is. but never had this problem and the mfs has been messed up for a while now.

unplug the multi function switch and try jumpering the harness to verify the switch.
