Question about 2003 Chevrolet Silverado 2500HD
Parking lights work properly but headlights will not come on until I turn truck off during the delay before all lights shut down. They will not work in auto or manual mode but the lights themselves are fine and have power to them once ignition is turned off.
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.

Chevy has had Problems with the Wiper Motors on these Trucks for a Long time now. On some Models they Issued Recalls. On My 95' I just Replaced the Wiper Motor and have had NO Problems Since!

Was sent in by another poster, just posting his results which fixed mine. Problem was relay $50.00 at GM only.
Check the relay module. 45 or 46. on the engine relay block. you can swap the two they are the same part number, then you will know. Dont start the engine, just check the lights. If it works replace the relay module. You may have to order the part from the parts store. Or go to the dealer to get it.

Replace light switch. Reach under the dash and find the switch you will feel a button on top of the wight switch push it down pull the switch knob all the way out, (Unhook battery first) then unscrew the beauty ring then pull the switch down and then remove wire connector and go buy a new one and replace it. if your a big guy it may give you a problem, but replace it before it burns up your wiring harness.
