Ac problem blower works but no cold air, heater does work

Hi @ricardoalbino

Below is an image showing the location of the A/C compressor fuse and relay in the engine bay fuse block.

If they're OK then try the following:

With the vehicle safely parked i.e. hand brake on, transmission in Park, open the hood and stand next to the side of the engine and have someone start the engine and then get them to turn on the A/C in the car.

You should hear the compressor clutch engage. (bit of a clunk sound)

When the engine is running and the A/C is not turned on, the compressor is not turning. When the A/C is turned on, the compressor clutch is energized and engages with the compressor and this causes the compressor to start turning, driven by the serpentine belt. The serpentine belt in the engine is routed via 9 pulleys and one of the pulleys is for the compressor.

It is the compressor that creates the cold temperatures.

If you don't hear the compressor clutch engage when the A/C is turned on and the fuse and relay are both OK then it could be a wiring problem (relay not being operated?) or a faulty compressor clutch.

If you hear the clutch engage then it could be a faulty compressor or a lack of refrigerant in the A/C sealed system.
