No Problem-Glad to Help! About the Best way to get to that wire and find out which one it really is is to get the Voltage Tester that I told ya about Before. Orielley Auto Parts has the best Selection and Really know their Stuff. If you don't have one near you go to Auto Zone and tell them that you need to locate a Faulty wire as Cheap as Possible and they can Help ya. When you get to that Point open the Hood and disconnect the Headlight harness from the Light (will work the same with other lights too). With the Headlights OFF and the Ignition turned to Start Check the Gold Leads inside the Harness for Power. The Voltometer Instructions will let you know what you are looking for, Probably 12 on the Meter will let you know that there is Power going to the Lights. If that is all good then go to the Fuse Box and Locate ALL the Fuses that have to do with Lights. Leave the Fuses in and Check the Gold Parts where the Fuse fits into the Box. If you find it you can always run an External wire from the Lights back to the Box. Sometimes the Fuse boxes are a REAL BEAR to get to and work with. Let me Know what you Find!

Headlights are on, turn bright lights on and lights go off.


Sounds to me that you have a bad dimmer switch.

1998 GMC Sierra has running lights and high beams but no low beams. Headlight switch is not the problem


first off, be sure your low beams aren't both burned out. it happens all the time. next check your dimmer switch operation. (i'm betting on low beams burned out) good luck.

2001 GMC Sierra headlights won't come on. Located 3 each 10Amp fuses that were blown and replaced them, however, headlights didn't come on.


what fuses were blown and replaced? Theres a TBC fuse under the hood, along with a Headlamp Relay. Theres a R HDLP and LT HDLP fuses, make sure they are getting power, and are good. If the LT HDLP and RT HDLP fuses are good AND getting power, then the TBC fuse and the relay is good. then I would suspect the Hi-Lo dimmer switch bad. The LOW beam ground wire is YELLOW, the high beam ground is PURPLE. see if high beams work, if they do, then I suspect the dimmer switch is bad.

Dash lights go out-


It could be a faulty dimmer switch. If the switch is fine then it might be a loose connection behind the gauge cluster. If you haven't pulled the the cluster off before. The plug is stationary and when you pull the cluster away it unplugs automatically. ButI would check the dimmer first.

1985 GMc sierra boggs out at idle


Sounds to me that the carb. is bad, most likely its a Qjet, best thing to do here is to have it rebuilt, but better yet get a replacement, unless you know someone that will rebuild it for you witch i dought, they don't call them Qjunk for nothing.
