On my 2002 GP I am noticing occasionally with AC on ,the driver side air output gets warm ,compared to the passenger side. If i cycle thru the air / heat /def. postion switch or interrupt the air flow in anyway it corrects the problem. Sometimes for days ,other times for mins.
Is this "easy" to fix ,were are the flaps/doors ,can I lube them ?
I been under the dash once to put a blower motor in . . . that worked ! That was 3 years ago, this flap / door thing just started to happen.
