SOURCE: The Heater fan in my 2003 GMC Yukon XL will not turn off

I don't know if you already fixed it, but I had the same problem on my 03 yukon, TysonRicky is right. In my case it was the blower control module. You can find it right under the glovebox. It cost me close to $100 for a new one, but very easy to replace. Can't even imagine how much it would've cost me if I had a mechanic do it.

SOURCE: WHAT PARTS DO I NEED TO TUNE UP MY 2003 GMC YUKON

you don have to do much to that gmc as long the coil is good, just replace all 8 spark plugs, air filter and basic oil and filter change; use good brands of oil, such as castro, mobile, shells ect. if your the original owner and have high miles and never have replace thermostat, I would go ahead and have it done, I would not wait until it fail and over heat on you. if you have done lot of pulling with your vehicle and have 75-100k mile, have your transmission flush with new filter, it will give the tanny life last a bit longer.

Where is ac orfice on 2005 yukon ?


Most GM products have the o-tube located inside the evap metal line where the high side hose connects. Evacuate the freon, then disconnect the high side line. Look in the metal line coming out of the evaporator and there it is. These can require that you carefully screw a screw into the plastic part then use vise grips to remove. Usually, these are replaced along with the filter/dryer when recharging the system.

No power to yukon xl compressor


Could have lost freon charge, or a faulty pressure switch or other electrical problem.
A mechanic would check for system charge and power at the compressor clutch.

Need a schematic of a 2002 Yukon XL AC system.


you could look for a paper tag with the part # on it but more likely if its missing you describe the hose to the auto parts person/ approximate length,and where does it connect to at both ends-the a/c compressor,near the firewall,the a/c condensor which is in front of the radiator and looks like a "skinny"radiator-if you know the names of the A/C SYSTEM PARTS.or the parts guy might be able to pull up a diagram on his computer screen.hope this helps you.
