a/c would blow cold for 10 minutes then blow only warm air, a/c would consistently do this for past couple years(car is only driven rarely as it is not my main ride), so i finally I took the 1991 crx si to a reliable honest shop and they thought the ecu was not sending a signal to keep compressor on, so they had ecu rebuilt($400),also the rebuilt ecu did not solve problem so the honda shop did not charge me for labor or parts,now compressor does not come on at all. They sort of gave up on it so does anyone out there have any ideas?

 

sounds like you have a refrigerant leak.

System is probably flat, lo pressure swich is still open.
Pull the cap off the access port and depress the valve. Is there pressure?
