#246 of 308 2003 Yukon Front Fan Problem
Jun 13, 2011 (5:59 pm)
I have a 2003 Yukon with manual dual A/C and rear A/C. The problem is with the front A/C fan. The lowest speed on the fan stopped working 6 months ago with the top four speeds (#2 to #5) still working. Last weekend, the #2 to #4 speed on the fan stopped working. The highest speed still works. The front A/C also cools on lower fan setting when driving fast with internal recirculation button not activated. No fan when stopped or driving slow. No problem with rear A/C.
Saw from posts that problem could be blower resistor or the climate control system needs to reset(from SNEREM post). My question on the reset. SNEREM states to pull the A/C and HVAC fuses.
How many fuses need to be pulled and where?
The drivers side fuse box has one heater A/C fuse and one HVAC fuse.
The engine fuse box has two fuses for the A/C compressors - do these need to be pulled?
The best part is that I got the extended warranty to 7 years/70K miles. The truck now has 70,500 miles and is 6 months out of warranty.
#247 of 308 Problem w/ rear a/c blower

I have a 2003 yukon, the a/c and heat work great, the problem is when I turn off the power the rear blower still runs at a low speed, running down the battery overnight. Do I need to replace the blower motor resistor.
#248 of 308 Another Yukon AC/Heat control problem on 2004

I had previous battery problems a month ago that were resolved with cleaning and replacing the + lug. Now my wife said the driver side blew hot and pass blew cold and the radio reset itself. I bought and installed a new battery. I first installed a computer memory saver. The last time I swapped the battery out the Memory Seat Module lost its software and it cost $80 for the dealer to reload it.
Now the only thing not working is the A/C and Heat control unit in the dash. The buttons and dials are back lit but no functions and no display. Nothing comes on when you press any of the buttons. I checked all fuses under hood and on driver side and nothing is blown.
The electrical engineer that designed this system should be a crash test dummy!

Took the car to the dealer. Problem was the blower resistor. Dealer fixed for $200.

behind the dash on the passengers side there is a blower motor resistor that controls the fan speed it could possibly be burned out

Hi coreams. Did you ever figure out what the problem was? I just bought an 03 Tahoe and the previous owner had the fuse pulled out for this reason. I thought it was just broke. I replaces the fuse and the rear blower would NEVER shut off. I couldn't adjust fanspeed either.

Hey Testdepth. I also am having the exact same problem. Drivers side blowing heat, passenger side blowing cold. I tried two 'recalibration' remedies, including disconnecting the battery for a half hour. Now I am just getting backlit buttons for the front control unit. Back works and blows fine.
Did you happen to get a fix?

I hope you have fixed this problem by now. I got frustrated after I wrote the last post to you, went out and disconnected the negative to the battery. Let it sit for about an hour, reconnected it, and now everything is working fine.
Good luck, let me know if it helps.

Thanks for the info fix as i still have the problem and am very willing to try this as drivers side heat likes to go on intermittently during 110 degree weather. Frustraighted
