The HVAC blower on my wife's Saab died on Friday. The A/C compressor had been squealing for the past few weeks, and the actual cooling capability has been weak for a while, so I took the opportunity to investigate that as well - turns out the tensioner was broken, so I fixed that too. Now the A/C blows colder - but I think it's
too cold - it gets down to -3°! The secondary problem is after a few minutes, the compressor turns off, and then the system just blows warm air. I'm sure these symptoms are related, but I don't where to look for the problem. A couple months ago, I added a little bit of refrigerant hoping that would fix it, but it didn't make any difference. I suspect it may be over-charged, but I don't know if I should bleed some off or what.
