I HOPE TO GOD THAT YOU'VE CHECKED THE FUSE! IF NOT, EITHER THE FAN ITSELF OR THE FAN SPEED CONTROL ON THE DASH. BEST WAY TO TELL IF IT'S THE SWITCH IS WITH A MULTI-METER under the dash on the passenger side there are a couple wires that have to be plugged in or replaced. this is a common problem with escorts I had a similar problem. Check the connections to the blower motor, located under the passenger side dash next to the motor housing. The plugs on my car got corroded from AC condensation and came loose probably by being hit by passengers feet. Try making sure those connections are tight and clean.
underneath the glove box
Not grounded properly.
A blower resistor can be replaced, in your 2002 Oldsmobile, by removing the resistor wiring. Remove the retaining screws. Reverse the process to install the new resistor.
You will only have high speed fan
heater blower resistor has to be replaced. you have to remove glove boxthe resistor is to the right of the heater blower moter
If the blower only works on high the blower resistor is most likely the problem and should be replaced. On rare occasions if the car has blown the resistor more than once the blower motor shouuld be replaced.
blower motor resistor needs to be replaced
replace the blower motor switch
The front blower resistor on a 98 Dodge Caravan is replaced by removing the cover and disconnecting the wiring harness. The resistor can then be pulled and a new one put in its place.
