Question about 2004 Toyota Corolla
I checked the gas and it is ok. I also connected the compressor directly from the battery and it started working perfectly. I'm thinking it is the magnetic clutch relay. What could it be if it wasn't the relay?
If it engages when you bypass, it is not the magnetic clutch.
It could be a relay or the low pressure cycling switch. I would jumper the cycling pressure switch connector. If it runs, I would check to be sure you have enough pressure first with compressor running. If ok, change the cycling switch

looks like fuse # 8 "heater control relay- ac clutch relay-cooling fan" fuse runs the 12 volt side " black and yellow stripe wire " pcm or ecm runs the ground side "red -blue stripe wire"- what else do you need?

Sounds like your A/C compressor coil is bad.I would suggest replacing clutch disc,pulley and coil or you can put a complete compressor assy. on which is a little more expensive.

Try checking the low pressure and high pressure switches. If one of these are faulty it can keep compressor from working. Take a paper clip and jump the ports on the plug in for the switches and see if the compressor comes on if it does then that switch is bad.

Testimonial: "Makes very good sense. Logically you don't want the comressor to run with no refregirant in the system. I did not know about this fail safe mode. "
Difficult to describe, but I will give it a try.
Inside the driver's side fender, close to the front of the car, there is a bracket that is held in place by one bolt, but which has a short horizontal bar as part of it which has two large clips encircling two cylinderical devices which have wires clipped into them at the bottoms. The one closest to the front (radiator) is the compressor clutch relay. The other one is the condenser fan relay.
Hope this helps you find it.

The a/c relay is located behind the dask pockett in a series of 3 on a metal brackett, unpulg each, one one at a time, till the lights in the control unit goes off and then plug it back in,If this doesnt work then disconect the ground cable on your battery for 15 sec and reconect . After this your light will not flash and you can turn on your a/c and it will work,thats is if your freon pressures are correct so as to give the low pressure switch enough pressure to send 12.50 volts to the compressor so the clutch will kick in.I hope this helps you out..
