The HVAC blower motor may fail. This is commonly caused by water entry through the cabin air filter areas during heavy rain or snow. Failed blower motors should be replaced. Our technicians tell us there is no special fix for this issue at this time.

    HVAC Blower Motor Do NOT turn off even with key out. No solutio until now. Every time I park, I remove the electric connector. Otherwise, I'll lose another battery ($ 200.00 ). The manual and FUSE Chart doesn't show any relays identification. I'm lost !!!!
