Having problems with your 1990 Geo Prizm ?

Where is the location of the speed relay for blower motor on a 1990 geo prizm

Answers :

Not a relay but a resistor pack, and it should be mounted in the heater case, close to the blower motor-follow the wires from the blower motor back to the resistor pack. Unplug the connector and remove the screws holding the pack to the case, to remove and replace.
Try the glove box first. take it off.
if the fan fails on all speeds but high the resistor is blown
the resistor gets hot so is fan cooled too.
thus its odd location. off the glove and look.
