2003 A/C issue

I have a 2003 v6 4WD 4Runner and my air conditioner blows warm air. I replaced the clutch relay and checked the Freon level and it is good. On occasion the compressor will kick on and the air get cooler but when it shuts off it never seems to kick back on? I'm wondering if I have a faulty Freon pressure switch? I never get the flashing A/C light on the button either. Any ideas?

 

I'd say first thing is hose off your condenser. It might be packed with mud/sand/dirt/whatever.

Then I'd consider replacing your ac compressor.

 

This thing has never seen mud or dirt yet......It was garage kept and was the wife's car of the guy I bought it from.

 

Hose off the radiators anyway, you'd be surprised

 

Is the compressor coming on with no cold air? When it does work is the air cold like it should be?
The next time it will not engage check to see if you are getting power to the compressor. If you have power and the compressor is not engaging then the compressor is toast. If you do not have power then jump the pressure switch and see what happens. Let me know what you find.

 

I had it serviced and it seems I have a leak behind the dash. It works good now but will slowly leak down. I have a cracked dash and a recall letter to get it replaced so I figure when I schedule the dash replacement I'll have the coil replaced. Thanks for all the replies.
