1999 528i here.
Two weeks ago the AC compressor took a dump.
Had my local mechanic replace the compressor, drier and valve.
Now the AC works but not very well.
Took it back and he verified the freon level was good. He tested for
leaks and could not find any.
Before the original compressor went bad, I could keep the temp at 68 and
worked great. Froze me out.
Now, I have to turn it down to like 64 to get any decent cold air coming
through. But it's struggling to cool, and certainly not 64!
In addition, the AUTO function is not working. Using manual settings I
can turn the fans up pretty high. But as soon I select Auto the fans go
to a really low setting and never move from there. Even on the manual
setting the fans don't seem as strong as it used to be.
Do you think this is the final stage resistor?
One other thing, I think the fan clutch might be on it's way out. It's
working but starting to sound like an air-raid siren in the background.
Any suggestions appreciated!
