After an unusually long and snowy winter here in New England, the last thing I expected was a non functioning A/C in mid-April! I've read the leaking evaporator posts and will re-charge it if necessary but I don't think my compressor is working. No "clicking" or apparent electrical draw. What can I check to determine compressor function vs. low/no refrig. My 01 will be 5 years old next month, no warranty and has never been back to the dealer, hate to start now! Thanks, Jim G
