Has anyone had a climate control system error pop up once it started raining?
If YES how did you fix this issue?
Thanks in advance.

 

Make sure your sunroof drain tubes are clear and not clogged which could lead to interior water leaks. Check the carpet up front under the dash to see if it is wet or if anything under the dash is wet. There are youtube videos showing how to clean the drain tubes with weed wacker line. Some shops use compressed air.
Or your A/C drain tube could be clogged and should also be checked and cleared the same way. It is easier to reach from under the car.
