Hi - I brought my 1990 9000T to a mechanic because I my AC wasn't cooling as well as it should have IMO. They said that there were some codes coming from the ACC, and that they will try to add more refrigirant to the system. They replaced the ACC with another used one which cleared all codes, but in the process of adding more freon (or whatever it is called these days), they ran out, which I think means that the car now has actually less freon than it had before because most of it went into their tank. Anyhow, it appears that now the system is constantly heating. I feel like I'm sitting in front of a fireplace when it's on no matter what temperature I set, so I just keep it off. They checked all the flaps and they are not stuck. Then I had them put the old ACC back in - that didn't do anything. They insist on waiting for more freon to come in and seeing if that helps, and I'm sure it will, but I'm wondering if that has been the problem all along and what I perceived as weak AC was actually the heat and AC working all the same time? I understand that the way heating works in 9000's is that the heater core is always hot, and the temperature is regulated by directing the air through or away from the core. Could it be that because of this the air is always being warmed at least a little, but because of the summer heat it feels to me like it's being warmed a lot? Is this some sort of a weird and complicated wiring problem, is this something that commonly occurs, or is this not a problem at all? Any advice/suggestions would be appreciated, I'd like to have this resolved, and I'd like to be armed with some information when I go to my mechanic next week to get some more freon. P.S. These folks do specialize in saabs and in the past they have done great work for me. Dan Sent via Deja.com http://www.deja.com/ Share what you know. Learn what you don't.
