SOURCE: The rear problem with a 1999 gmc sierra truck

do you know if you have a limited slip rear diff?
if you do your grease is worn out or if the fluid was replaced it need to have a friction modifier put in the diff (can be found at any auto part stores.)

if its not a limited slip diff you might have spider gears going bad. then you need to remove the cover on the diff and inspect your spider gears2f73bce.jpg b440737.jpgand these are the spider gears

SOURCE: 2003 GMC Sierra heater Blower wont shut off

My 2003 Sierra's blower came on by itself in the garage while I was sleeping and ran the battery completely down. I had to replace the blower switch located under the glove box next to the blower at the bottom of the right corner of the dash. The switch is in front of the blower and held in by two screws. Disconnect the two wire connections. This is a "dealer only" part and cost me 65.00. Also check the wire harness with seven wires connected to it for melted plastic. It will be marked "ABCDEFG". If it has melted, you'll need to replace it. Pay attention when reinstalling either part, that the wires "ABCDEFG" match the switch in that order.

Check TPS for smooth and linear electrical response over the entire range of motion. If the response is jumpy or erratic at all, replace TPS.

My 95 gmc wont start when hot starts and runs cold


Im guessing it's a 4.3 L engine. Sounds like your coil is acting up when the truck heats up. Bad coil, or small wires going to the coil

My 95 sierra dies and won't start. no lights on dash then suddenly lights come on and truck will start. please help.


first check the connections at the battery. make sure there is no corrosion between the cable end and the battery.

When you say it wont start can you hear the starter cranking the engine over or is the vehicle completely dead?

If its completely dead I would check for power to the ignition switch. if there is power than I would check for power out of the switch. If there is no power than possible the ignition switch is failing.

I might be able to get you some wiring info if needed. just let me know.

It sounds like your alternator might be starting to go bad and the Battery Light is coming on because it is not charging the battery correctly. Have your Alternator checked with a volt meter, it should be reading 13 to 14 volts if working correctly. If not, replace your alternator.

1997 gmc sierra shuts off while driving


Had same problem with a Yukon. Turned out to be a bad fuel pump (Won't show codes.) When cold ran fine, heated up, no pressure. Would start after sitting for about 1/2 hour. When engine dies on you check for fuel pressure under the hood.
