The one problem that may cause poor AC service is that the condenser may not
be properly cooling the high pressure gas and that may not even be an air conditioning
system problem but an engine fan clutch or an electrical fan problem.
Any vehicle will either have a mechanical fan that is attached to the engine
or it will have an electric fan that is controlled by relays and the computer.
So, if the electric fans don't work or the fan clutch is malfunctioning to where
it is not drawing enough air through the condenser you will get poor AC performance.
When this occurs, you are going to have a high side reading of beyond the
specs. Where it will normally be around 300 psi, you may get 400 psi on the
readings on the gages, on the high side. |
