2003 Chevrolet Silverado 1500 Questions & Answers
2003 chevy silverado, cd/cassette/radio, has
Sometimes these radios have what is called a logic lock up. First thing to try is to remove BOTH positive and negative cables from the battery. Then while holding both cables away from the battery, touch the metal ends of the cables together and hold for 20 seconds. This will usually reset locked electronic modules. Hook them back up to the battery and try radio.
Our 2003 chevy silverado is cranking slow in the
difficult one this ,without doing the tests myself its difficult -? slow cranking is either a iffy battery ,or too small for the current draw ,failing which its the windings on the starter motor ? now if as you say these have been checked then only one thing left and thats to renew or fit another one to double up so to speak and the earth strap from chassis to engine but i would be inclined to fit another cable from battery negative to the engine direct and see what happens ,
I have an 03 Silverado 1500 4x4. The blower motor
You need to replace the pig tail connector for the blower resistor. The contacts corrode/burn and will take out the new resistor. The actuator motor needs to be cycled through all modes to "learn" where it is.
Lost all power to my passenger door in my 2003 Chevy Silverado
Look for broken or corroded wiring in the door, especially where the cable goes from the body to the door. You will probably have to remove the door's interior trim panel for testing and inspection.
Visual: a wire with a nick in the insulation surrounded by a greenish stain is probably corroded through. The wire would have to be cut and spliced at that point. Use an automotive grade self-sealing or heat shrink ene-to-end splice, or put heat shrink tubing on the wire, solder the splice, then shrink the tubing over it. If the wire is part of a wire bundle, tape or zip-tie the splice to the rest of the bundle, other wise secure the cable to a support (away from possible contact with moving parts!) at or near the splice. If the door or the frame around the door is heavily rusted, you may have a bad ground connection.
Electrical: use a voltmeter or 12v tester to check for power in the door. Check the wiring to the lock and window switches first (especially red or pink). If you don't find any that read at or near the battery voltage with the vehicle accessories turned on (driver's door working), then you know it's a wiring problem. Measure voltage between device connector terminals and a good frame ground point (there may not be any power at the window or lock motors unless the corresponding switch is activated).
