D44Runner

I have an 88 4Runner. When I bought the truck, the blower for the heat only went from off to high. None of the selections in between did anything. Now, something happened, and the blower doesn't run on any selection. Any suggestions on what the problem might be.

Blower motor resistor and the possibly the fuse now that it's dead.

If I remember correctly, the #3 speed resistor goes and then all the speeds except for #4 work. It could be something as simple as the fuse, or it could be the switch, relay, heater blower motor, or the wiring. Change the resistor pack after you get the #4 speed working again. Here is a link on changing the resistor pack:
