Question about 1999 Oldsmobile 88
My ac & heater does not work. It has worked in the past sporadically. It worked fine up until about 9 months ago. Since then it may have come on a total of 10 times. It acts like it has a short. I've check the fuse. Please help. It is horrible driving in the rain with no defrost.
Disconnect the wire from the fan, turn the car on, test the voltage between the connector to ground (chasis) on all fan speed settings (high,med,low). If you have voltage at all settings (approx. 12.3V on high and less as the speed setting is lower) then replace the fan motor (about $50 at autozone). If there is not voltage on all speed settings you will also need to replace the blower motor resistor (about $12 at autozone). The whole process takes about 20 mins.
