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

#256 of 308 heat and ac problem for 2003 denali
Jul 24, 2011 (7:11 pm)
if you will look under the hood on the passenger side where there is a silver can that the ac tubes run into i think its called a dryer if you will unplug the wire and clean it with electric comp cleaner from the parts store and let it dry good and plug it back up and then wrap it with metal tape like they use for air ducts in a house to keep moister out of it, the ac leaks water down on that plug and causes alot of problems. i hope this works it did for me.

Jul 29, 2011 (3:39 pm)
Could be due to a plugged cabin filter. You need good air flow to keep this from freezing. The guy that told you that the unit had a low pressure switch was partially correct. The switch on a car is to detect low pressure as in the coolant is lowering in pressure due in part to low air flow or low coolant. Slightly low refrigerant will usually cause more cycling of your compressor. This is to prevent ice build up. Because in a car you can adjust the speed of your fan whereas in your home your ac runs at one speed usually there is no need for a shutoff switch. I have heard that condensate off of your line dryer "where this switch is located gets in the switch and causes problems". The clogged line is improbable as this would cause low flow in the refrigerant and low cooling not greater. The problem seems to be related more to the pressure switch and air flow than anything else.
