I have a 1997 Oldsmobile 88 the fan won't run I put a meter on it and the fan was good

It could be the fuse, the relay or the fan motor. Start by checking the fuse and if it's good swap the relay with one with the same number if the fan doesn't run unplug it and use a test light to check for current if the test light lights the fan motor is bad. I hope this helps. Take care.

I assume you checked fuses for condition and power to and through the fuse to the fan. Locate the fan motor and check for power and ground with a volt ohm meter. Check for continuity thru the motor t make sure it is not bad.

check for any fuse or relay,or if you ca not do anything just ask a qualified electrician to help.

CHECK THE OTHER COOLING FAN FUSE AND RELAY.IF BOTH GOOD HOT WIRE COOLING FAN TO SEE IF FAN RUNS IF NOT YOU HAVE A BAD FAN MOTOR NEED TO REPLACE FAN MOTOR.IF FAN RUNS WHEN YOU HOT WIRE IT.FAN MOTOR WIRE CONNECTORS HAS A SHORT.

Barring the simple blown fuse every time my fan has quit working on all my cars it was one of the following. 1 the bearings went bad in the fan and the fan became sticky. you can tell this by rapping on the fan motor itself while it is turned on, if it starts then it is sticky and doesnt have long to live. 2 the motor burned out completely you can tell this by applying 12v from the battery directly to the motors contacts in the proper polarity + to + - to - . If you are not sure how to apply power to a motor to test it you might want to have someone that knows how do it for you. if it doesn't run pretty good sign the motors dead. 3 there is a fault in the wiring and you would use the test for #2 to determine the motor is still good then start checking the wiring and switches. I usually check in the following order, glance at the led embedded in the AC switch on the AC console to make sure the unit has power , rap on the fan housing because its out in the open on the firewall under the hood and im lazy, check the fuses just for the heck of it even though the AC unit LOOKED powered, curse a bit, apply power to the motor to test it. I have only had 1 car with mysterious bad intermittent AC wiring and 1 car with a bad switch the rest were all motors that went bad.

REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF STILL OVERHEATING CHECK TO SEE COOLANT COMING ON IF NOT CHECK COOLANT FAN FUSE AND RELAY.IF BOTH GOOD.HOTWIRE COOLANT FAN TO SEE IF IT WORKS IF NO REPLACE FAN MOTOR.IF FAN MOTOR RUNS FAN MOTOR WIRE HAS SHORT OR COOLANT TEMPERATURE SENSOR FAULTY.

blower motor resistor

Most likley your blower motor has a "dead" spot in it when you hit a bump it jars it to work. Replace the blower motor.

Check or have checked the blower motor resistor. This is usually how they act.
