Hi. My 2012 Ford Escape blower and A/C went out on me. The blower only worked on 3 & 4, not on 2&3. The A/C started blowing warm. I replaced the blower resistor, the blower came back but the A/C is still blowing warm. I replaced the A/C relay, no change. I measured the refrigerant and it measures as being full. The compressor is turning. If I leave the car long enough, a bit of cool air comes out then it fairly quickly warms up to room temp. Any suggestions?

 

What do you mean by AC went out? Blower motor you say 3 & 4 work, but also that 2 & 3 don't work, please correct/clarify. How did you determine the AC is fully charged, you can use guages all day but best way us to have a evacuate & recharge to make sure its truly at special. When you change from cool to heat do you feel a temp change?

 

I replaced the blower resistor, which solved the blower problem. The A/C problem persisted, so I replaced the A/C relay. I then used a gauge to measure the refrigerant and double-checked those values with the maker of the refrigerant, which makes me believe that the refrigerant level is fine. So if it's not the refrigerant, not the blower and not the relay, it could be the recycle pressure switch except when I look down at the compressor, it's turning fine, so I'm assuming that means it can't be the pressure switch or the compressor itself. I'm about ready to take the car in, but am wondering if there is anything an amateur like me can check or replace?

 

Do you have separate pass and driver temp adjustments? If yes does either side work correctly?

 

No separate adjustments. Funny thing is, after I changed the relay, the A/C got FREEZING cold and I thought I had it but it slowly went back to room temperature.

 

I'll look up and post related wiring diagrams tomorrow, honestly it sounds like there's a decent chance a shop will need to look at it though.

 

Thanks, Scott!

 

Ok so after looking over the wiring diagrams theres not much more to do without a higher end scan tool that you can view live data on.
Unless you want to spend a good bit on diag equipment I would recommend bringing it to a shop.

 

Thanks, I appreciate your taking the time to look at this.
