AC

Ac will not come on. I've tryed passing the high and low switches and fuse and the relay. But if I ground one side of the relay the cluch ingages.

It's a 92 mm.

Ac pressure is good. I've tryed grounding the temperature sending unit. It's a 5 speed.

Got the truck to rev up when Ac is turned on. But still no power to the relay that puts power to at compressor.

40 on low side. Don't know sour the high side. But hard to really check with out the compressor running. But 40 shout make it come on.

Ok. I vacuumed it down and charged it and the low side is at 80psi and still compressor not kicking on.

What's the cluch cycle switch? The cluch will ingage if I put power to it.

Were is it on the high side?
