I am having a problem with my A/C and EATC. I cannot get the A/C to
engage. My compressor and clutch at about 2 years old, and the
cycling switch is brand new. I have tried shorting around the cycling
switch to no avail. The other thing I noticed is that the outside
temp shows about 30 degrees below the actual temp. I tried swapping
the ambient air temp sensor from my 92 and had the same results. I
ran the self test on the EATC unit and everything passed. Where
should I look next?

Thanks,

Titus Lloyd

If the outside sensor is reporting too low a temperature (or if the EATC is sensing too low a temperature), the EATC will not try to engage the A/C to cool the car. Shorting around the low pressure switch will not work because there will no be any voltage on the line. The only A/C operation will be intermittant cycling in defrost mode (tried that setting yet?) Since you've already swapped in a known good ambient sensor, the next step would be to swap out the EATC.

Over the weekend I tried swapping out the EATC head unit. I still get
the weird temperature results. Any other ideas?
