2000 Camry dash mounted A/C-heater fan speeds 1&2 don't work, 3&4 do.

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?
