On my 2000 Tahoe, transmission switches on dash, don't do anything. I checked fuse (#24) and it appears ok. Lights on switches do not light up at all. However when I turn on headlight switch, they all illuminate. But, not the little rectanglular light on the switch. Any ideas???

I have the same issue with my 2002 Chevy Trailblazer. How did you resolve this problem?

Thanks

If you have replaced the switch, and it is still doing it it sounds like you definately have a short somewhere in your wiring. On the other hand if the dimmer is in the turn signal arm ( forward bright back dim ) the problem could also be there in the dimmer switch, such as a short being caused by that dimmer switch being faulty.Auto Zone and Discount Auto Parts both test a lot of your electrical problems for free, and/or may have some knowledge to more accurately pin point the problem. Not sure about Pep Boys or some of the other discount auto part chains.

SOURCE: all lights work inside and out except all headlights will not

check the fusebox, mostly fuses are uite easily recognizable by small icons similar to the icons on the switches on your dashboard, find the one for lighting and verify if it is still proper. If not, replace it.

this got easy after a while 2 ways, i had friends who would not take the time to spend 8dollars to buy a harness connector for a new cd player and would splice everything together like takeing the red and yellow wires and connecting them all together as one. this drains ur battery unless ur cd player can completly power down by the power button not all do... but keep this in mind on GM cars the 2 wires of the same wires like purple the one with a black stripe is ground they go together stripe on stripe also there is 2 extra wires one is ORANGE and BROWN u dont need these dont even mess with them even if u have a connector block them off THESE TWO COLORS IS FOR FACTORY STEREO IF SO THESE WIRES CAN AND WILL MAKE IT SO U DONT HAVE DASH LIGHTS so always buy a connector ond dont mess with these wires block them off and dont ground them out.
