Hi everyone,

A friend of mine was recently having some problems with her 97 Lumina.
The battery wasn't holding a charge, so a friend of hers replaced the
battery. Then she had some noises when backing up which she couldn't
duplicate at Myers or Midas, so they couldn't fix that either (Though
she's suspicious of CV Shafts). After all this was done, now she's
having a problem with the A/C. When she first starts the A/C it just
doesn't blow the air from the vents, but it does from the defroster and
the floor. However after 10 minutes of highway driving, it finally
starts blowing from the vents.

I'm assuming it must be vacuum lines or the vacuum control unit in the
dash of some sort having problems.I have no experience with Lumina's or
Chevy's for that matter. I figured I'd ask.

Thanks,
Jason
