Toyota heater problems

[Max Power]

So the heater on my 89 pickup will get hot but the fan will only work on the high setting. It used to work all the time then low and med low stopped blowing. Then a year later the medium high setting stopped working. Now I am stuck with high only. i replaced the switch and that did not fix it. Any ideas?

there is a resistor that has small wires like a light bulb filliment that burn out. I was able to just streatch the wire back across and fixed it.

Very common problem in the 84-95 models. 99.9% chance that its is your blower motor relay.

Not sure on the exact location should be behind the glove box somewhere. Its a 1" black cube looking thing that you should be able to get at any parts store. Call around some places want quite a bit for such a small part.
