02 Dodge Grand Caravan ES A/C problem

I have a 2002 GC ES with an A/C problem. The temperature here in Iowa got up to 85 and the A/C will not engage. I have checked the fuses, and the relay, all are good. I had no problems with this last summer. Also, there is a terrible knocking in the motor (3.8l V6 with 42k) at idle and crusing speeds. I tried Lucas oil and 10W30, but it only worked for a week.

Thanks in advance for your help.

Assuming the compressor is in good shape and not causing the knocking noise you need to check for a proper charge of freon in the system, if it is low the low pressure cutout switch will not allow the compressor to turn on.

Thanks for the tip. I recharged it with R134A and it works like a charm.
