There are several ways to verify the compressor is good. One is to activated with 12V and the other is to take coill resistance which should be about 3-5 ohms. If you activare the compressor verify that the pressures should read about 35 low and 150 high + or -

That Toyota also has an A/C amplifier controller which have been known to go bad. It is a black box about the size of a big cigarette pack and is located in a slot in the evaporator housing behind the glove compartment.

The A/C circuit for you truck is a bit complicated. I will be glad to send a schematic if you want.

All A/C relays and fuses are located behind the glove compartment. There is a 10A A/C fuse in that fuse block #3 that you might have missed. Good luck and let me know.

Disconnect the compresor and try it. If the fuse doesn't blow you have a bad coil in the compressor
