*Skip this part if you don't want the back story*

Ok, a little back story, my AC hasn't worked right for a long time (almost two years) I've had it in to 7 shops and gotten 7 different answers as to what's wrong with it, basically the AC will get cold, then just shut off and start blowing extremely hot humid air, also water comes out of my bottom vents into the car and onto my feet. One dealership said that it was the thermistor malfunctioning, basically not telling the compressor to stop cooling and freezing up, this was a dealership where my parents live, so they told me what I need and had the dealership down here order the parts, they ordered the parts but said that they wouldn't gaurantee the work at all unless they diagnosed it. So they diagnosed the problem and basically said that they would have to take out the entire A/C and rebuild it because the "clutch" was too far away, total price - $1800 which for a '96 accord is far too much money.

*resume reading*

Anyways, today I was coming back from a trip and I've learned that my AC will work pretty well if I turn it mid way on the dial rather than all the way cold, and I had AC for about 200 miles, then I pulled off for a rest stop and when I started the car back up the air would not blow at all out of the vents. I'd originally thought that maybe the fan had gotten frozen, so I figured that I would leave it on and see if it came back on after thawing in the 100 degree heat. It did, but only after a few minutes and dumping a sizable amount of water inside my car. Then later in my trip the fan started blowing slower and slower then went off, so I'm thinking that maybe my AC drain hose is clogged and has perhaps flooded the unit. Does this sound right? If so, is it something that I can take care of my self? I'm just really tired of getting the run around on this thing at this point. I googled and came across a diagram that just didn't make any sense and I couldn't find the hose that they were referring to. Does anyone have any more specific advice?

Check for low pressure switch trips. May be low on charge.

Thanks for the reply. Sorry I'm a computer guy, cars are kinda foreign to me, do you mean low on coolant? (sorry if I'm butchering the terms heh) Anyways about a month ago when I took it in to the dealer to originally diagnose the problem they claimed that it was simply low on freon and pumped it full again (they also said that a hose was loose, but I think they just made that up because they couldn't find anything. I'd already had it into 5 different shops at that point, I think somone would have noticed a loose hose)

Yes Freon is a trade name but nonetheless it should be an R134a system for a '96. Probably should be gone over with a halide pump (very sensitive leak detector) as those hose fittings and compressor seals can be leaky on an aged system.

The DIY'r can charge it with UV reactive DYTEL and wait a few days and snoop around with a uv source such as a INOVA X5 UV flashlight.

The first time I took it in to the dealer they claimed to have tested for leaks using a dye that shows up under certain (UV if my memory serves me) light. They didn't find any leaks, but the second shop said that the compressor itself was leaking and that he couldn't find any traces of a previous test. No subsequent diagnosis has turned up any leaks. I dunno I'm not as concerned with the AC working intermittently as I am with the fan no longer blowing. Thanks again for the post, I know this is kinda like trying to explain a problem to a doctor over the phone, tough to give an accurate diagnosis without having seen the problem heh.

Find a shop with references for A/C work and you should get an honest answer.

Compressor seal leaks are common points of pain on aging systems.

It's a lot more common with larger systems than you think. Especially when you have lots of people and many want heat and many want cooling. The solution is a dual duct system with mixing boxes. So a chiller and boiler run all the time. Efficient? Sure if comfort index is number one. Anyway we're drifting waaay off the original topic here. :Q
