I have a 2002 Suburban that the AC went out on in 2011 right when we were heading out of town for a family vacation. I live in Arizona so it made the drive out of state and the drive back terrible. I had it fixed at Brake Masters when we got back. It was like $1400 to fix everything. I can't remember all what they did but I think they changed the compressor and the blower.
It worked fine the rest of 2011. In 2012 I started having issues with it now and then. It wouldn't blow cold air unless I turned on the AC for the 2nd row. That was intermittent. Then in 2013 that became in the norm, and I checking under the hood for some other reason and noticed cold air coming from one of the lines into the engine compartment. So I took it back to Brake Masters to have them look at it. They said that wouldn't of been caused by anything they did, but to find out about fixing it I would have to pay to have it looked at. I skipped it. I don't know if it did it before they messed with it, but I doubt it. I bought the Suburban new. Now the AC doesn't work at all and Im trying to decided if I want to put more money into it, or buy something new. It only has 138,000 miles on it.

I have tax money coming so I'm going to at least have the AC checked out and see if it's going to be another $1400 or something more reasonable. if I remember correct, the cold air was leaking from where it right line that's leading into the cab like right above the accumulator. Anyone have that happen before? I would keep the Suburban if the AC doesn't cost too much to fix. If it's over $1000 I'll look for something else, maybe just drive this in the winter.

It's got a few other issues but it runs fine. I had a window regulator go out and I replaced it, then it broke again, along with 2 other regulators. The only window I can use is the driver side, which I can live with cause it was the only window I rolled down anyway. The EBCM board probably needs the solder fix, ABS lights come on after like 5 minutes. Needs an alignment, and maybe the fluids flushed, and new spark plugs. All that stuff isn't too bad, if the AC is reasonable.
 
Not sure what kind of line you are referring to but cold air isn't going to stop an AC system from working, a refrigerant leak will cause the system to stop working. A line passing through the firewall will have a rubber grommet around it to act as a seal. The mileage you have on the vehicle is acceptable providing the engine and transmission are still in good condition.
 
Well I wouldn't take it back to Brake Masters that's for sure. Changing a compressor AND a blower motor is just wrong.
Give a little better description of the problem. Do you have any OBD codes? E.g. door actuators failing?
 
No codes. Right now the AC doesn't work at all, before that it would only blow cold air when I had the back AC on, if I turned off the back AC, it would blow hot air. Cold air was blowing into the engine compartment, I'll try and take a pick from where I could feel the air coming in. It could of been a freon leak maybe, and maybe now it's out of freon. I'm going to get it checked out when I get my tax money. As long as it's not going to be another $1400 I'll probably fix it, cause it doesn't have that many miles.

Here's a pic of where the air was coming out, it doesn't come out cold anymore, could of just been freon.

I haven't tried the AC in awhile cause I knew it didn't work, but I just turned it on and it makes a weird noise. Here's a link to a video. The first half, the ac is on, the second half it is off.
