Q: Car overheating and not defrosting properly.

asked by on

Hi, I have seen this issue quite often on the PT Cruiser. This is typically caused by a failure in the heater core that is located in the dash. This part carries hot coolant into the interior of the car so that the air can be heated. When it leaks it will cause steam which causes the windows to fog up. This will also cause a low coolant level which results in engine overheating. The dash will need to be disassembled to replace this. For this job, it is best to enlist the assistance of a certified mechanic, like one from YourMechanic.com.
