Q: Air and heating system not working

asked by on

My car won't blow hot or cold air.

If your vehicle is not blowing air out of the vents, you have an issue with the blower motor system. There are many components of the system which could be causing the problem. The most probable cause is the blower motor assembly. Before replacing parts at random, I would recommend a diagnostic inspection by a qualified mechanic.
