06 Sentra climate control
My daughter has an 06 Sentra. The heater is constantly on no matter where you set the manual control knobs (on/off, hi/lo). The A/C does come on when you turn it on, so I know that works, but the systems only blows out hot air. I believe this is just a climate control unit problem; can anyone agree with my assessment?
What I need help with are the steps to perform to replace the climate control unit in the dash. Can anyone out there help?
