Another AC problem
To make a long story short, the AC is working, the air coming out is cool; however, the air is barely coming out and is only coming out of the top vent. It worked fine a few days ago, but now I cannot switch vents. I'm not sure what the problem is.
Any help would be greatly appreciated.
vacuum (idle w/ cam) maybe it's too weak to pull the flaps
right. But this would get better at higher RPM, higher vacuum.
If it's just bad altogether look for a loss of source vacuum,
a vacuum leak at the manifold would also follow this (hose
off, cracked fittings, cracked vacuum diaphragm etc. Might
check by ear for a hiss of vacuum under the dash. You could
pull the little control panel and check that it is receiving good
vacuum and whether it is switching vacuum between the
various outlet ports.
Wish I would have found that 2 days ago when I was sweltering in 100+ degree temps.
