All the vacuum operated flaps seem to work, the air changes direction when selecting the different options.
Or does it take a really long time before you get cool air or something?
Is there anything I can check? What could be wrong? |
Visually locate the AC compressor on the motor. Have someone turn the AC controls to on and see if the outside hub next to the belt starts spinning with the belt around the
pulley with the belt on it.
If it doesn't engage at all, most likely low freon. Needs recharged.
If it engages and goes on and off quickly rather than staying on 30 seconds or more then off a while then back on, low freon.
