Question: AC not working

I turned my tucson off went to the store, came out and bam my AC now no longer works. It was working JUST fine before hand. I had the freon checked, fuses and everything is fine. The compressor is not firing up. Any ideas.... My AC has always blown me out of the car - I just dont get what would have happened.....

Did you have the system evacuated and recharged? AC systems need a specific quantity of freon to function (not pressure). Quantity can not be measured without doing this.

Check for the signal on the AC magnetic clutch wire. If there is no signal you have an electrical or computer problem. Check relays and the climate control ecu, along with the AC pressure safety switch.

If the clutch has the signal but isn't engaging it's probably a bad AC compressor or wiring issue.

If the clutch is engaging the pump could be bad internally or another problem in the system. Check the rest of the components starting with the AC fan.

Otherwise I would recommend taking it to a professional AC shop.

Good luck to you.
