Test check: Test the HVAC control module for optimal operation. If your air conditioning system is malfunctioning, the outdoor air door and indoor air door flap intermittently even when the air conditioner is off, or doesn't respond at all to your specific temperature settings, or the air seems to be behaving inconsistently, there may be a problem with the air conditioning/heating climate control panel. Have it inspected and replaced as soon as possible.
Improtant: Please make sure to confirm your car model and OE number before placing an order, if you have any questions, please send us an email!
