Where's the AC "Cycle switch" on a 1993 ATX????

[Silver Bullet]

Can someone please explain where it's located, and possibly provide a pic if necessary? I have no AC, and will be doing some electrical troubleshooting to determine where my problem lies..........

Also... How do I jump the cycle switch properly?

ac pressure switch location

How about right there!

You need to remove the black plastic cover on the firewall to see the accumulator/dryer canister, the pressure switch is right on top of it.

To jump the connector, unplug the connector from the switch (just pull it off) and plug a paper clip into the two slots of the wiring harness connector. When you push MAX AC after starting the car your AC compressor should turn on regardless of the system freon pressure if everything else is working ok.

Ok... I checked the #17 fuse (It's fine).

I jumped the "Cycle switch", and turned the MAX AC on hoping for clutch movement... Still got no movement from the clutch!! The AC compressor with clutch was replaced (Brand new) two years ago.

I basically went through all the tests posted in this very informative article from Utah Ford Club http://www.utahfordclub.com/ace.htm

I also had no current on the voltage tester from the #2 or #4 wire

Any suggestions to what may be messed up?

?????? No clue what you are referring to.

Check for power to both wires of the cutout switch. If on only the pink wire, verify your R134 is fully charged. If so, replace the switch.

If power is on both wires, problem is either in the CCRM or the clutch.

* I should have been more specific!! I was talking about the wires on the "IRCM" thing...... I'll try what you said, and see what's up
