So last week i was driving with the AC on, was making deliveries for my job so I had been driving with it on for a while, everything was working fine, blowing nice and cold and hard, I stopped and shut the car off but didn't turn the AC off first.... I came back in the car and started it and the AC wasn't blowing... turned AC off/on still nothing....

So I thought maybe it had something to do with me shutting the car off while the AC was on...

Got home and parked and went to drive it a day or two later.... turned AC on and it was working fine again

Then yesterday I was driving with AC on, it stopped blowing for a second but then came back on.... I also shut the car off once while I still had the AC on... turned it back on and it was still working so don't think that's the cause...

Then today, I got in the car and started it and turned AC on, was working fine... made a 2 minute drive to the store.... parked, shut the AC off, turned the car off.... came back to my car and started it and went to turn the AC on and not working

 

Maybe a bad AC clutch?

 

system pressure could be low. Temp changes affect pressure and the system won't work with low pressure.

 

is there anyway to test if the pressure switch is bad?

 

I'd hook a gauge up first. Pretty sure parts places do it for free.

 

So I talked to the previous owner and he said he had the same issue.... he took it to mechanic and they fixed/replaced the motor blower ground cable.....

Does that sound plausible?

 

So is it actually not blowing any air at all when it faults or is the air just not cold? If your problem is you aren't blowing air I would definitely look at the blower/cables.

If your AC is tripping out from a sensor or too low of pressure, your car will still blow air it just won't be cold.

 

it was blowing cold when it was blowing

Before after running for a while it would stop blowing then I would park it and then a day or so later it would work again... blowing nice and cold

But now it stopped working even after waiting a day or two of waiting..... so now it doesn't blow at all

 

If your problem is that the blower isn't even turning on then it has nothing to do with your AC refrigerant system. You should be able to switch the controller over to heat and it won't make a difference. Sounds to me like you might have a dead spot in your blower motor? I would first check to see if you are getting power to the blower. If not figure out why not. If the blower is getting power and still not working then the problem is most likely with the blower itself.

 

Could it be a problem with the knob? Would ANY speed not work?

 

You keep saying either stops blowing or stops blowing cold. Those are two very different things.

 

Check the wiring to the blower motor, my brothers 06 sedan does the same thing. He usually moves the wires a bit and comes back on.

 

I never said it wasn't blowing cold

 

Could you tell me where that is? I'm not a mechanic or very hands-on but I'm not an idiot lol... I just don't really know where things are located under the hood.... and I really don't know anything when it comes to AC systems/electrical stuff

i posted up a few posts that I talked to the previous owner and he had the same problem and had the motor blower ground cable replaced

 

So take it to.a mechanic... It's impossible to diagnose online. Especially when you don't know what you're looking at.
