meant to also say @ac1 have u done a HVAC reset first and what faults codes did u get when a diagnostic reader was plugged in plse
With ignition off press and hold the ECON & RECIRC buttons whilst turning ignition on (no need to start car).
The control module will then compare the current HEVAC actuator motor positions with the values stored in the module and will indicate an error by flashing the ECON LED.
If there are no errors, the LED will go out and the system will function normally.
To confirm that there are no errors, turn the ignition switch to the OFF position, then back to the ON position.
Observe the operation of the programmed defrost LED.
If there are errors present, the programmed defrost LED will flash and the system will attempt to calibrate itself.
