Next time it does it take your fist and hit the top of the console armrest, toward the rear of the armrest, if it stops suspect the Rear Seat Audio module, I'm assuming you have one because I've replaced 3 in the last few months for this exact problem,it sounds like an alt. whine up and down with the engine speed, yes the amp is bolted to the floor under the console, you can pop that RSA module out and let it hang until it makes the noise and then lightly hold it and tap on it to see if the noise goes away. The RSA needs to be programmed to the truck at a dealer.
Hope this helps

SOURCE: Rear heater not working

Possible blend door motor (controls amount of heat that comes out). Or heater core in back is clogged, or air bubble. If your able to locate the two heater hoses that run to the back of the vehicle and check to see if there hot next to the heater core. if both are hot (be careful not to burn yourself) then the flow is good usually. need to pull the panel off and check the blend door motor is working when you turn the rear heater control to cold to hot. let me know what you see

SOURCE: whirring noise front end 2003 yukon denali xl

Your front pump in the transmission could be going bad. Check the transmission fluid for level and condition. The fluid should be bright red and not burnt (dark in color like burgandy). Best thing to do is take it to a transmission shop and have them check your truck for DTC codes with a Tech 2 scanner and have them do a transmission line pressure test. The whining can also indicate low on transmission fluid and that's bad, you may have burnt some of the clutch packs already and shorten the life of your transmission. Good luck and keep me posted, be glad to help.

Could be the latch mechanism for the door is sticking. You could try using some white grease on the latch and the contact where the latch hooks to. You can purchase the grease from most auto parts stores. You will not need to use alot. Just apply a small amount to the mechanisim and then work it in using the manual handle. Then open and close the door several times to feel the "action". Then apply a little more and repeat. This should loosen the latch and get it working again. Also make sure that none of the tension springs have come loose on the latch. And check the seal around the door and make sure it is not pinched and has a proper fit.

Electrical short?


Most likely a loose serpentine belt on the engine or it needs to be replaced and is squealing when you press the gas.(fan belt)
Why go to the dealer?Talk to friends for info on a local garage that has a good reputation.
Always get an estimate on any repair,don't just drop your vehicle off and sign a work order without a price and description of what they are going to do to fix your vehicle.

I have a 2005 yukon denali with the bose stereo and my rear speakers dont work


The Bose system is set up differently from other radios...each speaker has its own seperate power amp, so you have two connections to each speaker, the 12v power, and the low level signal...you can use a front speaker to plug into the rear wires and if it plays, you need a new speaker/amp...if it doesn't, you're missing power or signal for that channel...

Humming sound coming from the small speaker over my head ?


That "speaker looking thing" above the drivers head on the headliner is a part of the climate control system.

Here is the GM bulletin regarding it if you are running in to these issue:

Document ID# 1639237

Subject: Buzz Noise From Headliner Above Driver - keywords ac air aspirator cover fan grille HVAC interior microphone sensor speaker temperature vent vibration #PIT3511 - (03/29/2005)



Models: 2000-05 Cadillac Escalade

2002-05 Chevrolet Avalanche

2000-05 Chevrolet Silverado, Suburban, Tahoe

2000-05 GMC Sierra, Yukon, Yukon XL, Yukon Denali

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:
Dealer or customer may comment that they have a buzz or vibration noise emanating from the headliner in an area that looks like microphone or a speaker.

Recommendation/Instructions:
The plastic escutcheon grill, which is round and about the size of a half dollar and located just above the driver to the left, is the interior ambient temperature sensor. The sensor is used in conjunction with the automatic HVAC (C68). On occasions, this sensor has been known to make a buzz or rattle sound. The sensor uses a small fan to pull air over the sensor. This buzz noise may be intermittent.

Although it may not be possible to alleviate all of the buzz or noise from this sensor, Engineering has found that if the sensor is installed incorrectly that it may bind and cause the fan to make a buzz noise. Remove the sensor and while doing so check for any binding. Reinstall the sensor and re-test. If the noise is still present, the sensor itself may be noisy and require replacement.

when changing the battery on a General motors product you run the risk of erasing the PCM you will probably have to go to the dealer and have it reprogrammed please only go to the dealer if not done right you will have more problems.
