Ac issues. Ac light stays on but no cold air

Hey guys, replaced ac clutch after air went warm during the winter. But no change. Tried new relay and checked Freon pressure. Seems like the ac button flashed when pushed on but now canít turn light off. Could the ac control board be bad?

Why did you change the clutch? Was it getting power and not working?

I thought I showed power from the harness but today I’m not showing power to the clutch. There is only the ground and power to the clutch right?

Re: Ac issues. Ac light stays on but no cold air

The "power" wire runs thru a low pressure switch. If the system is low because of a leak the switch will remain open to save the the compressor. Now is the big question. What can you do about that? That answer begins with your skills. You will need to see how flat your system is. If it is simply a little low to just now affect lp switch you may be safe to simply add a snort and get the pressures right after correcting the leak. If it is really flat I'd fix the leak, pull a vacuum to make sure you fixed the leak. If it holds a vacuum I would change the drier, pull another vacuum then charge it up.

Okay, found out that the ac light goes on automatically and has nothing to do with this issue. So did get the clutch working now but still no cold air. Checked charge again and shows full. Not sure where to go from here.

How are you checking the charge?

Try knocking on the line where it passes through the firewall (and hope that it doesn't change anything). Expansion valve is on the other side in the EVAP box.
