In the 1999 Trooper the relay is sbove the inside fuses. It is above the fuse door, so that the whole panel by bottom of the driver door must be pulled. Don't know if that helps for 1990. Note: My fuse, relay and motor are good, but no power to motor. added 1/22/2008 The blower motor resistor is located on the housing located on the firewall. This housing is were the blower motor is.
there is a resistor that controls the speed and should be near the blower motor its called blower motor resistor
I own a 1994 Isuzu Trooper, the blower moter is located inside the truck under the glove box.
IT turns the heater on and off!
do you need to take the dash off
i do! i do! a used one $100. (910) 300-9286
Coolant leaking from the heater core.
it could be an alternator problem,is it an automatic type heater(no manual levers)
The blower unit is located i the passenger compartment above the right front footwell, ahead of the glovebox. The resistor is located in the housing just to the left of the blower housing.
Isuzu Trooper was created in 1981.
Blower Resistor block for the heater/ac motor on my 1996 TROOPER, is located on the heater/ac unit in the cab, passenger side. Remove the glove box,(2 screws on the bottom hinges, then open the box and it will lift out) You will see an opening on the left side with a wire harness of 5 wires. Unplug the harness, and remove the 2 Phillips screws and the resistor block can now be removed! About 10 minites total labor to do it youeslf. Beats being charged a couple hundred bucks to the dealer for parts and labor. Part is about $55.00 retailer from the dealership, check online and you should be able to order it from a discount parts supplier. From what I've found online, when the heater/ac blower quits, it is usually the restistor block about 90% of the time. Regards, Gary
