This is normal....the air conditioner compressor takes up to 15 horsepower from your engine, and under certain conditions, can make a noticeable difference.

No it is not normal. I have a 2001 Yukon that this happens too. It just began within the last year. And I have an 07 yukon that this does not happen to, even with lights on, radio blastin, and turning in circles at idle speed.

GMC Yukon showing Reduced Engine Power, broken oil gauge, running hot


I've had the same problem with the reduced power and tps sensor which is your gas pedal. I replaced it but the problem still existed. I then changed the throttle body and harness to the throttle body but still had the same problem. So I traded the vehicle. I did everything the dealer suggested and I just cut my losses. The Yukon overheating would be a different problem and should be easy to fix.

Here is a TSB (Technical Service Bulletin) for your vehicle for loss of temp control.
File In Section: 01 - HVAC
Bulletin No.: 01-01-39-007
TECHNICAL
Subject:
Loss Of HVAC System Mode and/or Temperature Control 

(Reroute Wiring Harness)
Models
1999-2002 Chevrolet and GMC C/K Pickup Models (Silverado and Sierra) 1999-2002 Chevrolet and GMC C/K Utility Models (Avalanche, Suburban, Tahoe, Yukon, Yukon XL, Denali) 2001 GMC Sierra C3
2002 GMC Sierra Denali
2002 Cadillac Escalade, Escalade EXT
Some customers may comment that they cannot control the HVAC system modes and/or the temperature. These concerns may be intermittent.
Cause
There may be poor terminal contact and/or bent terminals in connectors C206 (RPO C68 automatic HVAC controls) or C296 (RPO C60 manual HVAC controls). Excessive tension on the wires due to the wiring harness being miss routed in the instrument panel carrier may cause these conditions.

If the warranty campaign is over i am sure they can or may have in the system on how to correct the problem.
Good luck and hope this helps, keep me posted if you need help on to the repair procedure.

2005 gmc yukon 5.3l burn quart of oil every 2000 miles


Is it really burning blue smoke out the exhaust or leaking out all the wrong places like valve covera and front and rear seals? There is no solution here except find out the cause of the loss and fix it.

Check to see if the power steering pump is still turning. If you have a broken drive belt (serpentine belt or "fan" belt), and the pump doesn't turn, you have no power assist. If the pump is still turning, check the fluid level in the reservoir.
