2001 ZX2 A/C Problem
I have a 2001 ZX2 and the A/C quit blowing cold. I am not getting any power to the compressor, and both pressure switches have checked out OK.
Are there any relays in this line? Any help will be greatly appreciated.

Re: 2001 ZX2 A/C Problem
The compressor won't engage unless low side pressure is about 55 psi. If that isn't the problem, it's a matter of tracking down where the power is being interrupted, whether it's a fuse, pressure switch, relay, etc. The first step is to locate a wiring diagram and go from there.

The AC problem is due the failure of a small relay inside the CCRM (Constant Control Relay Module). This little module is mounted in the engine compartment underneath the air filter housing. The CCRM relay failure on 98+ Escorts/ZX2s is well documented by thousands of people (like me) who have the same or similar AC problems. With my ZX2 the AC operation was intermittent - sometimes working, sometimes not. You can either have the CCRM replaced (about $200 for the part), or you can attempt to repair your CCRM. I can supply more info if you wish. Email me for more info.

Re: 2001 ZX2 A/C Problem
When I turn the AC to Max or just regular setting, and the temp knob is set to cold, i don't get cold air. I noticed that the AC compressor clutch does not engage. From what I have read on the web, one person replaced the CCRM and this fixed his problem. Appearently, the CCRM ($150.00) controls the signal going to the clutch magnet that causes the compressor to run. But i'm not 100% sure if this is the same problem that I'm having.
I will check the pressure switches to make sure that they are working properly. I don't want to spend over $350.00 worth of parts (reman. AC compressor, accumulator/receiver-drier, orifice tube/thermal expansion valve, couple cans of R134a refrigerant, and some other misc. parts like o-rings), so first I will check out the electrical side of the system. If any one has any ideas... please let me know. Thanks in advance.
