Climate Control Problems
Hey everyone,
My grandfather'* '95 bonneville with 120,000 miles started having problems with the ac system. First, air only blows onto the windshield. The switch that controls air flow seems to work fine because it turns the system on and off, and turn the ac compressor on and off on the correct positions. I suspect that the problem lies with the thing that actually sends air into the right place, maybe a motor or something. The second issue is that the ac compressor started making a medium pitch growling noise when its on. No noise when the compressor is off. Could it be the bearings, or is this soemthing normal? Thanks in advance for any help.

Check for a disconnected vacuum line at the vacuum reservior between the master cylinder and maxifuse box under the hood. With no vacuum source, the climate control defaults to defrost.

Awesome, thanks a lot for the vacuum hose idea. I'll check it out on Monday. How hard is it to replace the compressor. I'm sure I can take it off with no problem, but i'm not sure how the 2 hoses come off. It looks like they go into some sort of a round fitting, but there are no nuts or bolts that I could see.
