A/C not blowing cold

2000 Tacoma prerunner, v6, 127k miles, a/c light goes on, but isn't blowing cold. I hear a click at the lower right near passenger side when I push the button but no cold air.

At idle the engine revs higher when I turn it on, and lower when off.

Any ideas?

 

1. Find the front of your AC condenser. It is normally located in front of your radiator. If there are leaves or other dirt or buildup blocking it, remove them and clean the area.

2. Look under the hood at the AC compressor clutch. If your air pressure is normal but the air is hot, you may have a compressor problem. Checking to see if the compressor clutch is engaging is a simple visual inspection. The compressor is usually located towards the front of your engine, just inside the grill of your car.

• Your car should be running with the AC on to check the compressor clutch.
• The compressor looks like a small motor with a large wheel on the end. The wheel (which is the compressor clutch) should be spinning. If it is not spinning, you have a problem with your compressor.

3. Check the tension on the belt of the compressor. It should be tight. If it is loose, you need a new compressor belt.

4. Find any coolant system leaks. One of the most common AC temperature problems is low refrigerant. The AC system is closed, so refrigerant should not be lost unless there is a leak.

• Look for oily residue on or around hoses that attach AC components together. Oily spots may indicate a refrigerant leak.
• You may consider using an electronic leak detector, which can detect much smaller quantities of refrigerant.
• There are also some testers that use dye, UV light, and protective glasses to find leaks.
• If you do find a leak, you will likely need to hire a professional to repair the leak. You will probably need new parts too, as many of the components cannot be repaired or patched.

 

Could also just be the temp control servo. Check this thread out. Has a pic of the location of the servo mechanism. Take a look down there and see if it's moving while you turn the temp knob back and forth.:

So this is my condenser. Notice fins missing. Doesnt appear like I have a leak. Blows sort of cold but not ice cold. Compressor working fine. Should replacing make huge improvement?

 

It might, it sure isnt gettin much air through that thing. Pressure washer do that?? Nightprowler is right too, that deal he is talking about has been known to go titts up..
