I have a 96 Park Ave with Auto climate control. When I increase the temp the warm air blows on the driver and cold air blows on the passenger side. Also defrost blows no warm air and rear seat vents blow warm air. I had a similar problem this summer when the A/c was blowing cold air on driver and hot air on passenger and then it started to work. Can anyone point me in the right direction, temps falling and hard to drive with no defrost.
