AC still blowing warm after new expansion valve, compressor, pressure switch

Post by drbruno4 »

AC still blowing warm after new expansion valve, compressor, pressure switch. Problem I had was I put in a new ac compressor control valve because ac was hot then cold. I must have not put the o ring clip on right. Was working great then the control valve blew out of compressor. So I put new control valve on again, this time making sure the o ring clip was secured. Vac system, added new R 134a. Still warm air. I did notice that refrigerant was not going in that good, seemed slow using manifold. So I next put in an expansion valve. Vac, put in r134a. Nothing. Still warm air. The clutch was turning but not sure compressor was working? So next I put in new pressure switch. Vac, put in Freon. Still nothing, warm. Checked fuse #32 15a. It was good. I don’t know what else to try except condenser/ dryer? Any help would be great!!!
