A/C unit

Quick ? My dads 91t is havin an ac issue. It's getting no power. If we run a wire from the + on the battery to the wire that's connected to the ac unit, it kicks right on and works. Is there a fuse for this?

Somewhere.

You don't suppose the control unit is not engaging the compressor for a reason do you?

if there is not enough freon it wont turn on.. but I assume you check that.

It could be a faulty Pressure sensor then. Just start tracing it back and see where the power stops (or starts depending whree you start)..

theres an easy fix for this.

pull out the a/c and roll down your window =)

it could be that you dont have enough freon to keep the low pressure switch on.

there is also a 25 amp fuse for the compressor in the right side kick panel. Yes thats on the passenger side. you have to remove the panel to get to it.

Not exactly, they are circuit breakers and relay over there.

There are fuses also and a one specifically for the a/c clutch. My a/c went out and i noticed the clutch would not engage. i had just had the a/c charged recently so i knew a a/c clutch would have to have a fuse. I could not find it so i looked in the wiring diagram TSRM and found it.
