Saab 9-3 Problem Report
Saab 9-3 Inability to Maintain or Control AC or Heating Temperature
The shaft for the air blend door can fail creating the inability to adjust the AC or heating temperature. The AC or Heat will not maintain the proper temperature.
The vents will not blow hot air at all even with the climate control knobed turned to high heat. Just before the issue happend a clicking sound could be heard when adjusting the cc knob from cold to heat. - Visitor
The driver's side vent will blow cold, but the passenger side will blow slightly warm. Not going to fix as the entire dashboard has to be removed to get to the little rod that failed. For me, it's a problem to be endured rather than fixed. - alexbucell
My AC just quit working one day and were still trying to find out what and where the isssue is coming from. We replaced the blower motor resistor but now are trying to figure out whatelse needs to be replaced. The AC and Heat are still not working. - Visitor
still trying to determine the solution - Visitor
Cold air only comes out of the driver side vent. Dealer said probably faulty or failed blend door mechanism. Glad I have a warranty to cover the labor of getting in there and replacing the part - Visitor
