So, my wife's Escape, the a/c doesn't work, the clutch isn't pulling in? The system has lots of pressure, the gauges go right over when I put them on, the fuse is good....Is their a low ambient control? If I put the defrost on, should the compressor cycle? It's a 2010 V6 fwd Escape .....I'm glad the a/c works in my van .....
There is a possibility that the evaporator temp sensor is biased low. I have had various pin fit issues with some of the later harnesses as well. Tap on the dash just above and to the right of the instrument cluster. Sometimes just unplugging and plugging component back in corrects the problem. It can be frustrating to say the least. I had an instrument cluster with a bad circuit board cause this problem along with several others. The ac pressure transducer(on the discharge line near the condenser) can also cause the instrument cluster to not allow the compressor to engage. There is a low ambient strategy that won't allow the compressor to engage below 45 deg F but above that, it should operate in MAX, normal, floor/def and def.
Dave, You can go to Autozone's website and get wiring diagrams. Then try jumping the low/high pressure cutouts and see if it works, may just be a bad switch...
Probably not relevant but I used to do some quick tapping and probing and find problems without having to do charts etc.. I can't tell you how many times I found a clutch that was just slightly out of spec on the gap and tapping on it would cause it to engage. Found alot of condensor fans out by tapping on them also..
Thanks, I'll have a look.. I haven't checked to see if the clutch is getting voltage or not, yet...but it's got to be a switch holding it off...
Just an update, for anyone that has an Escape. While driving it the other day, I noticed that the blower motor would only run on numbers 3&4...so that led me to believe that the fan resistor was bad....$20 later, and fifteen minutes ( a little longer since my wife has the glove box jammed with stuff) I swapped out the resistor, now the fan runs on all speeds, and the a/c works!! I don't care how or why it's wired like that, I'm just happy it was a simple fix.
That's nice. My brother-in-law always goes on and on about Honda makes their cars so easy to work on. They put the resistor for the blower motor behind the blower motor in my wifes 92 accord wagon. You have to disassemble the entire passenger section of the dash, and pull the ECU out, and pull almost the entire AC box(and condenser, the manual actually says to empty the refrigerant and then re-fill after, I figured out how to do it without that), the blower motor box, and the blower motor... Just to get at the resistor. I did this last year with junkyard parts... and I'll be doing it again probably this weekend to put in new parts as it went out again. I wish to hell she had an Escape after hearing how easy you have it.
