I sure hope you don't mean 35 lbs of freon !
When the ac compressor is running, the low side will read 30-45 psi under normal conditions. The high side should be around 250psi.
You need to be able to check both low and high to see if the system is full of freon. It holds around 4 or 5 cans total depending on make and model. Thats about 3 lbs.

What you will be looking for (in your engine compartment) looks almost like a large valve stem that you would see on a tire. It will probably have some kind of plastic cap on it.
It shouldn't be that difficult to find. You may want to search for an engine compartment diagram for your make/model/year vehicle.

I have the same problem with my Durango AC. I called the dealer and they do have clutch for my compressor available. I wonder how big of a job it can be. I got my A/C Charged thinking I am low on compressor gas only to find out after 135 dollars that it is my clutch that is not engaging. Cost of new compressor and labor factor added to it get to be a scary sum of money for 1998 model. Any one knows how to replace this clutch? Is it the front bold that is holding the entire clutch? Help amin

check cooling fan operation while ac on.If fan is working proper,will probably have stuck exspantion valve.

Just went thru this problem. There is probably a small amount of moisture in the system and it is freezing in the expansion valve. If the service hoses weren’t purged of humid air when Freon was add – that’s all it takes. I discharged my system and vacuumed it down for one hour and recharged it. All is well.
