A/C climate controls problems 2005 Silverado?

The drivers side blows cold but the passenger side is blowing heat. It does'nt respond to the control is there a relay or a fuse or is the climate control switch bad? If so how hard are they to change?:banghead:

Driver's side is working good,passenger side only blows hot. I've turned the knob up and down but it isn't responding. Do they have a fuse or a relay or is the climate control switch bad,if so are they hard to change? Is there a way to bypass the switch?:banghead:

I've experienced the problem of hot air on the passenger side of the vehicle for many years, and have simply learned to accept it. It's cheaper and easier than a divorce. As a result, most of my vehicles have had a passenger side air bag long before anyone else thought about it.

Is this a dual-zone control? That might make a difference. There is a separate damper motor in the dual-zone systems.
