Q: Coolant is bubbling

asked by on

My car's air conditioner gets warm while my car is not moving, and my coolant is bubbling.

Hi. Your concern sounds very similar to an event where the system cooling fan may not be working properly. If the air conditioning is cooler as the vehicle is moving, but warm when stopped, this tells me air flow is the problem. Have a technician inspect the entire air conditioning and cooling systems for mechanical or electrical faults.
