Regardless of the temerature selected on the control panel, my temperature is either full cold (cold position) or full hot (all other positions). A/C works fine and coolant is obviously circulating. It becomes impossible to comfortably regulate the temperature during the winter. Cable on Control Valve won't move.

Sometimes it work fine and cable on control panel moving smoothly.
Dealership ask $95 for diagnostic

Perform the foolowing to see if there are any trouble codes.

ENTERING SELF-DIAGNOSTICS
1. Turn ignition on. Set temperature control dial to maximum cooling, then slowly to maximum hot. After one minute, press AUTO and then OFF button. Simultaneously press AUTO and OFF buttons. See Fig. 2 .

2. If any problem exists in A/C-heater system when buttons are depressed, temperature indicator will light up a segment corresponding to the error code. The temperature indicator will then alternate every second between displaying "88" (all segments lit) and diagnostic trouble code segment. See Fig. 5 . If system is okay, segments will not light up.

NOTE:
Fault information is not retained in memory. In case of multiple problems, appropriate indicator lights will light up. If indicator lights "A", "`C", "E", "I" and "L" light up at same time, common ground for sensors may be open.

Can you please re-phrase step 1. Its a bit confusing Can you give me more detailed instructions. First it says to push auto then off. Then push them at the same time? Should the car be on or should the key ignition be in the on position. I'm just really confused
