Question about Cars & Trucks
I replaced the battery in my 2001 GMC sierra c3 truck and now my radio won't work. Can you help.
The reason the radio won't work is because of theft deterrent stuff built in radios now where if power is unhooked from the battery, you have to enter a code to get it unlocked. I would start by looking at your owners manual to see if there is a paper or page that would give the code you need to press to unlock it. If no luck there, I would go to the nearest GM dealer and tell them what happened and they should help you out and most likely not charge you anything.

First thing unhook positive battery cable, unhook main cable on starter selanoid and small wire on selanoid (there may be 2 small wires) There may be a bracket on front of starter that has to be removed, and then the 2 main bolts that hold it to engine block and it should come out.

First of all...does your truck have the retained accessory power (RAP)? If it does, the radio would always stay on with the key off until you open the drivers door. If it does have RAP and the door pin on the drivers door has went bad, then the truck doesn't know that you opened the door and continues to allow accessory power (although it would still cut off after about 20 minutes). If the interior lights come on when you open the door, then the pin is ok. If the lights come on, it could be the RAP relay. If it has gone bad, it is possible it is stuck supplying power and needs replacing. The relay should be labeled in the fuse panel, and there should be other relays in the panel with the same part number. You can swap a relay for the RAP relay and see if it fixes the problem...if it does fix it swap the relays back and replace the RAP relay. If the truck doesn't have RAP then it is possible the problem is in the radio..if you have a friend with a GM car or truck close to the same year you could swap radios and see if that fixes your problem...should be pretty simple. pull the cover off the dash, it just clips on, take out a couple screws that hold in the radio, unplug it and plug in the other radio. sorry so long winded...hope this helps you somewhat.

take off the cover on the top and bottom of the steering column just behind the wheel. pop the tilt lever out simply just by grabbing it and give it a good tug. then once you have the new switch and you get in there your going to need an inverted torx socket to remove the small bolts that hold the switch to the column. do not move the gear on the new switch make sure it lines up exactly as the old one did!!!!!!!!!!!!

The switch or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Sierra running 100% again soon.

Yes, the system is called Passlock, and malfunctions regularly. Go to this link for an explanation of how it works, plus some tricks and tips on how to reset it, or bypass it.
