STALLROMA

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

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!

I'M HAVING THE SAME PROBLEM. WHEN I SHUT THE CAR THE OVERFLOW RISES COMPLETELY TO THE TOP. WHEN I START THE CAR AGAIN, THE OVERFLOW IS BACK TO NORMAL. I JUST NOTICED THIS, AT THE SAME TIME MY A/C IS BLOWING WARM AIR NOW. CAN THIS HAVE ANYTHING TO WITH ONE ANOTHER?
