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.

Where is the fuse box on a 1997 Oldsmobile 88?


I assume the fuse box locations for a 1997 Olds 88 would be the same as for a 1999 - which are: (1) In the lower cover panel below the instrument cluster just left of the steering column - with a snap-off cover. (2) Passenger side 'kick panel' - side panel under the dashboard just forward of the door - lower cover panel underneath the dashboard and next to the firewall must first be removed. (3) Under the hood on passenger side on the firewall - need to remove black plastic outer cover (1/4 turn finger latches) then two black plastic inner covers (side spring latches).

Fuse box location, heater fan not working, fuse?


Check 30A fuse 3 in the right underhood fuse box but also the blower relay, the blower switch, the blower resistors, the mode switch, or 25A fuse 5D in the I/P fuse block could be at fault.

The heater fan quit working. How do I replace the fan?


Did you check if you are getting voltage to the fan motor? There is a small circuit board located near the fan motor (under the dashboard, passenger side) I have had 2 escorts and both had the circuit boards go bad. you can get one cheap at a junk yard

What's your problem?the fan for the heater quit working


I'm assuming the heat for the inside of your car. Does it work at all? On any of the speed setting? If it doesn't check fuses, check for power and ground at fan. Or if you can see it just bang on it with your fist sometimes that will get it working temp.

Heater only works when it wants to


could possibly be control head for heater/ac system. lots of gm vehicles have this problem.sounds like a loose connection, look under the dash on the right side near blower motor to check wires to blower motor

Ac & heater


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.
