I have a 1998 528I that has some issue with A/C. First it does not blow cold air with the system set for A/c, second the auxiliary cooling fan never comes on. So far I have replaced the auxiliary cooling fan with a new one, checked the voltage at the fan connector and found 12 VDC, checked the pressure of 134a on suction(low) side found about 35 psi(normal charge), the compressor is running, the vent inside is blowing normal air (not cold at all), high side refrigerant line is getting hot(as normal operation) when the a/c is on. I dont know what else to do or check. My primary concern is to get the auxiliary cooling fan running! I need help to figure this thing out! Your input is really appreciated.
have the same problem?
