Need Ac Help

[STALLROMA]

JUST PURCHASED 92 SC 400. A/C WAS BEYOND COLD-I MEAN FRIGID FOR ABOUT 10-DAYS. ALL OF A SUDDEN, HOT AIR. SEEMS LIKE THE COMPRESSOR IS KICKING ON. I DID NOTICE COOLANT IS AT VERY VERY TOP OF RESERVOIR WHEN I SHUT ENGINE. WHEN I START CAR THE COOLANT FROM THE RESERVOIR IS NORMAL(NOT SURE WHAT THAT MEANS) CAN ANYBODY HELP?

ALSO CAR HAS 59,000 MILES ON IT. LOOKS LIKE THEY CHANGED THE A/C SYSTEM IN OCTOBER 2006 ACCORDING TO A STICKER AND SOME MARKINGS UNDER THE HOOD!

Could it possible be that the line(s) is clogged? or maybe when they replaced it they didnt wire it correctly or forgot something..

Are you positive that the compressor clutch is kicking on? Have you seen the clutch engage? What A/C sticker is under the hood? r-12 to r-134a conversion?

the hood markings say 28 oz r134a. how would i see the compressor engage?

When the clutch is energized it locks onto the compressor and the serpentine belt spins the compressor. When the A/C is off the clutch just freewheels on the pulley. You should be able to see a plate on the A/C compressor engage with the pulley and spin, when the A/C button is switched on.
