Which fuses should I check, because it isn't blowing cold air?
I've already put Freon in it and coolant in the reservoir tank.

Hi,

There are a couple of fuses to check and a compressor relay. Take a look at the pics below. I attached the entire wiring schematic for the A/C system. I highlighted the power supply to the compressor, the fuses to check, and the relay.

As far as the relay, if there is a different one in the box having the same part number, switch them. If there isn't, here is a link that explains how to test one:

In addition to checking the fuses, make sure there is power to them. Here is a link that you may find helpful:

One last link. Take a look through this and let me know if anything helps:

Pic 5 shows the fuse box in the vehicle and pic 6 shows the one under the hood.

Let me know what you find or if you have other questions.

Take care,

Joe
