So my sister's car is a 2010 ford escape XLT and her AC was making noises and not turning on all the time, had a mind of it's own. we had it looked at, got it fixed, turned out the AC clutch was going out. ok, no big deal I figured that's what it was from the sounds.

fast forward a few months later AC stops working randomly again same as before stops working whenever it wants, no warning what so ever. Her dad comes down to help us take a look since we had just got it fixed and offers to pay to have it looked at again and fixed if needed. So we take it to the Firestone down the street(not our first choice just what he went with despite us warning him of the scams they get away with) and they say, oh yea it's the blower motor/resistor. We say oh ok cool we go through with the repair, they fix it up and it works again like it should... Right?

Nope does it again, same issue. We take it back to Firestone only for them to say it's the same thing and do the same repair again only to again a few weeks late shave it continue with the same issue. They're telling us we need to come in when it's not working so they can see what's wrong and see a master mechanic but because it's chooses when it wants to work or not, whenever we took it in it would randomly decide to work for them (just our luck).

Ok now we're present day. Still not working all the time. Wasn't working last 2-3 days. But today it decided to kick on. It gets extremely warm here in summer and my sister needs the AC, does anyone have any ideas as to what's going on or what/how to fix this?

One of the Firestone guys said it might be electrical issue and that made me immediately think maybe somewhere in the fuses maybe. But if that's the case why didn't firestone just check that initially as part of the look over the car before doing work? Please help!

When you say it doesn’t work what exactly do you mean? Is air blowing out the vents?

I mean like you can hear the compressor kick in but no air usually and if there is air its very very little like a breath of air through the vents but so little you can hardly tell

Is there air coming out of any place else? Sounds like a problem with the fan, not the compressor.

If it has a cabin filter , check it's not blocked or restricting air flow . Check all flap actuators are operating , for example

What exactly did they replace? If that fixes it I’d lean towards that even if it is temporary. There may be an underlying power or ground issue with that circuit.

No, no air anywhere else, like I said it has a mind of it's own when it doesn't want to work and when it does but when it doesn't it's pretty much completely dead like they never fixed anything in the first place it weird

Just had the filter replaced at an oil change/ tune up and I don't think it's the actuator because on the random chance it decieds to work everything else works fine it just doesn't turn on at all when it acts up

I would confirm all your connections to the motor are tight.
