98 S70 130K.... I turned on A/C and it's blowing warm air.. The clutch or compressor(located under alternator) clicks on and off continuously...

Usually when the compressor goes on and off it means there is not enough freon in the system...

Buy some r-134a and charge it up to 35-ish psi with the compressor running and idle held at 1500. Exact pressures based on ambient temperatures are on the back of most cans of freon. The service port is located near the windshield washer fluid tank.

This gives a good idea of what you need to do. Find a can with a sealer in it also.

Funny how this time of year the AC threads come about 1 a day.

Most of the time the freon with the sealer in it doesn't work for us because our leak is in the evaporator and the sealers work on seals.
