Q: Air condintioner won't come on.

The air conditioner blower won't blow

My car has 149000 miles.
My car has an automatic transmission.

Hi there, thanks for writing in. In most cases, when the AC or heater is not blowing air, it’s caused by an electrical problem with the blower motor or the motor is broken and needs to be replaced. The AC system has multiple actuators and relays that provide power to them, so you might want to start with buying a service manual for your Cadillac and inspecting each one. If you need help diagnosing the exact source of your AC issues or would rather have a professional mechanic complete this service for you, contact us and one of our professionals will complete an AC is not working inspection for you, and help you with any necessary repairs needed.
