Hey everyone so I got a 01 GS430, and now that its been getting cold in the Houston area I had to use my heater for like the first time since I got my car... So I turned on the heater and I set the temp. to 85 with the ac off and the dual climate off and I noticed that the left side was warm and the right side was cold... Has anyone ever had this problem, and is any one who knows what to do to troubleshoot this issue?? Any info would help... Please help!!! I cant take this cold weather!!!

 

New to me. So the right side was blowing cold air correct?

 

Most likely that the temperature "mixing" solenoid/motor has gone out. It's a motor that controls how much hot or cold air flow mixes in with the air being blown out the vents.

 

I got a 01 GS300....and my dual climate control is broken too....it wont allow me to set dual controls....basically my pass side is stuck at 65....but driver side can still be changed.
