I own a 2001 Yukon XL, 8.1 liter with 86,000 miles. 6 weeks ago, while driving on the freeway, the engine shut down for no reason. I was able to start the engine up immediately.
3 weeks ago the reduce engine power came on and shut the engine down with no signs of engine over heating. Then, a couple of days ago, the engine shut down similar to 6 weeks ago. This issue also happend the following day. Today, again on the freeway the engine shut down for a split-second, then came back on immediately. I live by the ocean and I was wondering if the salt air is working it's way into the fuse box inside the engine compartment, and causing all these issues.
July 15 update:
I took the vehicle to a reliable, independent, vehicle technician.
Diagnosis: replace the crankshaft locating sensor.
I also heard that GMC announced a safey recall for certain VIN numbers with similar symptoms (this may be old news to some).
Call GMC and provide the customer service person with your VIN number.
I allowed this technician to install the new sensor, for a reasonable price, because of the unsafe driving condition of my Yukon and 20+ years of trust with this repair shop.
Good luck to all.
I own a 2001 Yukon XL with an 8.1 liter Vortec. Recently, the windows for the passenger seats behind the driver failed to open. Before taking the vehicle to the dealer, I gently rubbed high grit sand paper on the windows' fuses. Now, the windows open with no issues.
I cannot guarantee this will work for you, but give it a try.
Tonight I heard a thud and now I am hearing a whirring sound and the gears are shifting slowly. Are we looking at a transmission repair???
2001 GMC Yukon XL Denali AWD.
I am thinking of buying it???
It has 152,000 miles. It's white outside, looks nice besides a few ground effects pcs kind-of loose. Leather looks a little faded, but nice inside, it seems to start right up, quiet motor & runs good.
Seller says it has a new transfer case a few months ago & a tune-up.
The ABS light & brake lights are both on when started & driven???
I also hear a vibrating noise under drivers seat? Sounds like an aquarium running type sound?
I also hear a clicking noise while driving coming from passenger seat area with A/C off??
Other than the 2 lights & 2 weird sounds, it seems to start-up & run really strong.
He was asking $6800 & is now asking $5400.
Any ideas or comments would be great! Thanks.
I own a 02 Yukon that recently went over the 200,000 mile mark. It still runs like the day I drove it off the lot. No sounds, no vibrations. The only work I have had done to it was a fuel pump at 157,000, besides one tune up and multiple services. It still has the original brakes and they do not make any noise. The vehicle has been great to me.
I have a 2003 Yukon SLT. I love it, but the carpet on the drivers side stays damp. I do not known why. Besides the carpet being damp, it runs like a charm. It is really pretty decent on gas.
I have a 2001 Yukon XL... I have 238,000 miles to date. I'm the original owner, from Atl Ga. I've driven the entire east coast (Fla to N.Y.) and once out West to N.O.. This has been a great truck, mostly highway miles of course.
So far I've had the water pump changed 4X's under extended warranty, the alternator changed once under extended warranty and may need a new one now, fuel pump recalled, 1 tune up last winter, tranny fluid change twice, had a clunk - thought it was the tranny, but was the universal joint wearing out, running on second set of brake pads, I've had the same stalling mentioned above -cleaned throttle body and mass air flow, which fixes it every time, otherwise I've had not much more truck stopping experiences.
The only pain in the butt is that all the interior lights on the driver side door, and the radio/air control lights on the dash have burned out and can't see a thing. Someone tell me, what is that gunk that comes out of the driver side mirror and causes that foggy look?!!! Is there a quick fix, or does it need to be replaced?
2001 Yukon XL.
Your rear A/C pan is clogged and water is leaking towards the front of your vehicle. I had water on the right rear passenger side and driver side.
The fix: behind your right rear fender there is a black plastic nipple. Squeeze the nipple like you are milking a cow, and this should unclog it and solve your problem.
I have got a Chevrolet 2002 Yukon. The ABS and the brake light is now on. I tried my best to turn off the light, but no use. I have also checked with my code reader, but there is no code present. Will any one help me? THANKS IN ADVANCE.
I have a 2001 Yukon XL with 79,000 miles, and just had a problem with the ABS light and brake light staying on. I live close to a Cadillac dealer. They indicated the parking brake had not disengaged and I had burned up my rear brakes. Paid $400.00 for new rear brakes.
A few days later the same lights came on and stayed on again. Cadillac dealer said the control module was bad and wanted over $1000 to fix it. But when I left the dealer, the lights did not stay on after start up. Then they would stay on sometimes and not other times. GMC dealer indicates they don't think the control module is bad, just a short in the wiring, and will replace the wiring and clean up the area around the module. Plan on taking the cheapest route first.
Hi. We have a 2001 Suburban, and our ABS light and brake light come on almost all the time. When both lights are on, it means that the ABS system is disengaged. We have taken it to numerous shops, including our dealer, local mom and pop shops, other dealers, AAA, and others. All have said it is the ABS computer module. #1300.00 to fix. It's safe to drive, you just don't have ABS. We solved our problem last week, by trading it in... Now we have a 2005 Suburban with a VERY wet front passenger side floor and a gross mildew smell. Trading one problem for another...... After reading this message board, I'm going to try to find this A/C drain nipple and see if that helps. Thanks for the information.
We own a 2003 GMC Yukon Denali XL with 85,000 miles. This is a great car, and we have had no significant repair jobs in the time we have owned it, other than having to replace the rear electronic gas shocks at about 75,000 miles.
Lately however, we, too were experiencing the same wet carpet issue alongside the rear passenger seat. We ruled out rain, including puddles from below and window leakage from above, and eventually pinpointed it to an unknown problem with the A/C.
After reading some of the earlier posts on this bulletin board about wet carpet and a clogged rear A/C drain, we decided this must also be our issue.
Just as the earlier posts describe, there is a black rubber nipple behind the right rear wheel well, just to the aft of where the A/C tubes go up into the vehicle. I slid under the vehicle behind the right rear tire, near the tailpipe, and with a flashlight was able to spot the nipple immediately. The opening of the nipple is only about the size of a small pencil eraser, and ours had evidently become clogged with a bit of dirt and grime. I "milked the nipple like a cow" (as one earlier reviewer put it) and instantly, about 1/2 gallon of water poured out of the nipple, streaming steadily for about 2 minutes.
All of the A/C water had backed up in the A/C tubes which run underneath the right stepside of the vehicle, immediately under the right rear passenger seat; they were condensing and the resultant moisture was traveling up through the floorboard and soaking the carpet pad and carpet.
Easy fix! $0, about 10 minutes of time. Great results! Thanks for the advice and directions!
