Dual climate control panel always blank?
Jeep is a 2002 WJ. The climate control display panel is always blank. When I press the a/c & recirc buttons at the same time, then rotate the temp. control knob CW one detent, nothing happens except the two yellow lights come on above the controls. So I cannot read any of the error codes that everyone talks about. I am hoping to narrow down the cause of no heat on the drivers side only the passenger with these codes.
I read somewhere else on the web that if the display is blank the a/c heater control must be replaced and said this control goes between the coolant resevoir and the heater core. My question is what has the a/c heater control got to do with the blank display. My son checked all the fuses and said they were okay. Is there a hidden fuse for the display somewhere?
