OK… past frustrated on this one… A good number of years ago, the blower fan that pushes air into the passenger compartment (for A/C and heat) stopped working when the 4-way switch (off, 1, 2, 3, 4) stopped working. Please, understand, I’m not an idiot when it comes to cars, electrical, electronics, etc. Just that I don’t know what it is to look for here. 10 years ago… I started with the obvious… the fuse/relay block in the engine bay. While there are icons for “Fan 1”, 2, and 3, I’ve surmised that these are for the radiator cooling fans. With speeds 1 and 2 not working, while 3 and 4 still do, I have to think it’s a relay/fuse type thing, but with there being 2 distinct “channels” involved. Problem is, I can’t determine how to find those “channels”. From what I’ve read, there’s a fan-speed-control RESISTOR, but when it goes out, it seems the fan speed should simply go to “high” (speed 4) and none of the others. I’ve still got speed 3 working. So, “relay” is the conclusion. Or… is it? The !#^&@* about all this is that I simply like “speed 1”, 2 if it’s like I’ve just gotten in the car and need to cool down quickly. But I’m stuck on 3 right now, and it’s more air movement than I like, as well as the noise. Anyone have any thoughts… preferably from experience? Chip Tredo Dallas

@djtempo ,Chip, Blower motor resistor could be the problem when 1,2 do not work and level 3,4 do work. Also check the plug and wires for the resistor for loose/damage/burnt. The link below may help if you would like to test the resistor plug prior to changing the resistor. 2nd link shows how to replace resistor. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. https://www.2carpros.com/questions/toyothttps://www.youtube.com/watch?v=cHZ2UpcZ
