I had A/C purged and recharged, mechanic said car needed a new relay to kick on blower on high. The A/C was blowing cold for a couple of days.
Replaced Fan Control #6 relay (K87). Even though there are 2 other Fan Control relays, #7(K26) & #8(K42). the blower blows on high speed but no longer cools.

check to see if the clutch is engaging on the front of the compressor.If not your coolant might of leaked down and shut off the comp.Check the static pressure of the freon in the system with the car not running and it should be around 50 or so if not you more than likely have low system pressure.
