my acura cl recently does whatever it wants as far as heating and cooling goes. sometimes when you start it up and set the temperature on 60 the heat stays on like u have it set on 90 degrees, and vise versa. It either puts out hot air or cold air, and u can't change it , all u can do is cut it completely off. It might stay on heat for a week and then decide to blow out cold air for a week. the control for where you want the heat or cold works fine, and so does the speed of the fan. when u select auto temp. the temp might read 90, but the air will be blowing out cold, it doesn't matter what u have the temp. set on it might blow out cold or hot. please help if u possibly can

Hi charles j,

Problem seems to be a fault with the air-mix motor or circuit. System is equipped with self diagnostics. Perform the diagnostics and see if you can come up with any codes.

ENTERING SELF-DIAGNOSTICS

Turn ignition on. Simultaneously press AUTO and OFF buttons, then release buttons. While buttons are pressed, indicator lights "A" through "G" will light up to indicate faulty component. See Fig. 16 . If indicator lights come on, test appropriate component.

NOTE:
Fault information is not retained in memory. In case of multiple problems, appropriate indicator lights will light

If indicator lights "A" through "E" light up at same time, common ground for sensors may be open.

I have same issue going on with my 98 Acura 3.0 CL. I couldn't see/find the referred Figure here to get more information. Would you be able to share it again here...... or any other possible solution for this similar issue, where once heater starts blowing hot air it doesn't stop even temperature is set to 60 or if it's blowing cold air it continues to do so even when temperature is set to 90.....
