Chrysler Repair: 97 LHS a/c, fuse block, refrigerant pressure

Question
I was wondering if you could tell me why the a/c on my 97 LHS quit suddenly? It was working perfect on our trip until we stopped to eat, when we resumed, all it would do is blow hot air. The control still works, showing the temp and adjusting the blower speed, so I do not believe it to be the resistor block or control head. I have checked the fuse block on left side of car, by drivers door, they are all good. Is there another fuse somewhere I am missing? Also, I am not sure if the cooling fans are kicking in. Thanks for any tips...greg

Answer
Hi Greg,
The things to check are first the belt that power the compressor has to be present and not slipping so take a look at that. Then when you turn on the A/C observe whether the clutch on the compressor engages by watching that the central circular area of the compressor (which normally sits at rest while the pulley carrying the belt rotates freely around it when the A/C is off) is now rotating and that the engine labors a bit at the moment it goes on. At that moment the fans should also come on. Now if none of that happens it means most likely that your level of refrigerant may be too low to safely compress it; there is a pressure switch which will cut off the system to prevent damage. It is also possible that a fuse may be blown which is located in the power distribution center which is the rectangular box under the hood near the battery. Those should also be labelled. There are also relays for the fans and the compressor in that box which could fail but are less likely to do so than fuses or loss of refrigerant.
So try checking the belt, fuses for any blown, and watch the compressor/fans when you ask for A/C at idle. Then if everything seems o.k. except the clutch doesn't engage and the fans don't go on then I would suspect that the refrigerant pressure is too low and needs a filling up.
