Air Conditioning not getting power

[knute_gis]

I just took my truck to an AC guy and its fully charged with no leaks. The only way we can get the compressor to kick on is to take the relay out and jump the terminals.

We checked all the switches and they seem to be OK. I took the AC heater controls out to see if I could jump the dash switch but there is 6 pins on it.

Can I run a wire straight to the relay with a switch for now until I get back from the power tour?

Does any body know which wire on the relay to run a hot wire to?

thanks, Kris

Also, I put a new relay in it and it didn't fix it

Check your binary switch. aka pressure switch

I have checked all three switches.

thanks

Not all three of them are "jumpable" as a test.

Did you install a three wire F-Body sensor in the A/C high pressure line, to allow the computer to control & cycle the A/C system?

[knute_gis]

No I'm trying to use the 305 harness to run it.

Please explain in detail I have no idea what I'm doing.
