Just bought an 02 Lancer. The a/c works great, can not turn the know to heat it is stuck and the a/c light will not turn off even if you hit the switch. Anyone have any ideas on where to start with the control knob??
Found the problem. The plastic piece that connects to the a/c heater control under the dash was designed wrong. It hangs up and when you try and turn the know it just stays there. If you put to much pressure on it you break the unit and have to replace it. If you go to mistu and get the new plastic piece it is only about $15.00 and a couple of minutes to replace. Fixes the problem!!!
