Can someone please tell me if the condenser fan should run whenever the climate control is in auto and set to 65. Mine never seems to run and the blower motor runs on full blast trying to cool the car down but it never gets cool enough. I have checked both relays for the fan and both have voltage to them, disconnected the fan harness and don't see any voltage at any of the 4 contacts on the oval connector. Any common problems it may be?

condenser fan does NOT always run when A/C is on,it only comes on when AC system pressures rise above a certain PSI or engine coolant temps rise above a set temperature.Generally mine is usually "off", but kicks on after sitting at idle with AC on after a few minutes due to the AC pressure rising in system from lack of normal airflow created from driving the car- as soon as car is up to speed,the fan turns off.
