Well it is finally getting warmer here in the rust belt and I thought I would try my A/C today and no luck. The compressor does not kick on. I have read a some older posts that say if there is no freon in the system the compressor will not kick on.
Is there a way to check to see if the compressor is good or works without putting freon in it?

 

I think you could run a hot wire straight to the clutch and engage it that way. Check your fuses and relay. I just had the same problem, added a can and it's ice cold now...knock on wood (been 2 weeks)

 

What JoePJack1 said. You can jump the clutch with a wire to the battery, if the pressure is too low it will not engage the compressor to prevent damage from not being properly lubricated.

 

Still no a/c compressor and looking for some more input before I replace it.

1) Turned the A/C on ...nothing
2) Checked the horn, it works...nothing
3) Swapped the relay for another...nothing
4) Checked and replaced the fuse...nothing
5) Checked for power going to the clutch and it is good...nothing
6) Jumpered the plug for the sensor by the accumulator...nothing
7) Checked for a charge and it is just ok, right on the line for high (the needle on the guage sits right on the line for normal and high), I did notice when I put the guage on, some green slime came out of the line...nothing.

Any feedback on this is greatly appreciated. Thanks

 

"Normally" that kinda gooey crap is stop leak. My step dad does ac for a living and said he's seen that stuff tear up alot of compressors.

 

Dont ground the switches, you have to jumper them. They are designed to break the circuit if pressure drops too low/too high.

 

I apologize, I did jumper the one switch in the drier. I ran a wire from one side of the plug to the other. I will correct it in earlier post.

You said switches as in plural. Is there more then one I should jumper while checking it?

 

One on the low side at the accumulator, (the one you found.) and another on the high side, I think it's near the compressor.... might even be ON the compressor.
