97 850 t--5 A/C and Vaccum Lines

Guest · Post by **Guest** » 03 Nov 2004, 17:47

My first concern deals with my a/c. After driving the car for about 45 minutes my a/c stops blowing air in the car. You can hear that the blower is still spinning but nothing is coming out. After som rest (usually a day) the a/c will again work, but shuts off after 45 minutes. I was wondering if anyone has had a similar problem and could shed any light?

Secondly, I got my car checked out because the check engine light was on. The code came up as EFI 2-3-2 which I was told that the vaccum lines and hoses were bad.

My final question is that I was wondering if by any stretch that these vaccum lines could have an effect on the a/c not blowing any air? I know it's a long stretch but I just want to know if it is a possibilty because I am having a discussion with the dealer and I basically think they are screwing me out of some money.

So if anyone could respond with some help I would appreciate it.

Thanks in advance

The Volvo AC is severely over engineered. There are multiple things that can go bad in the AC system. This is one area that I will go to my INDY mechanic to get checked out. It can get very expensive throwing parts at the AC and not fixing the problem.

I had a low pressure return line that would collapse when the outside temp hit 95 and above. On a hot day it would work for about 15 minutes and then it would collapse and the freon would stop flowing - hot air. I found that I could turn off the AC and wait 5 seconds and turn it back on and it would work again for a little while. I did this for a year until I had worn out the switch. I replaced the $100 dealer only switch and finally broke down and carried it my mechanic who had it fixed in 45 minutes and $400 later.

I was wondering if you wouldn't mind referencing your mechanic? I'm actually going to school in Bloomington, so it might be of help. If you don't want to post it publicly my e-mail is [email protected]

Thanks again
