At some point I'm doing my blower motor but before I rip it to bits I'm just trying to get it clear in my head just what is happening.
Last year I got a bit of a hot electrical smell then lost 1st and 2nd speeds, on investigation a couple of the wires going to the switch (just at the terminal ends) had slightly melted. I cut and soldered on new terminals and fitted a new switch..... all seemed fine. But after a few weeks I noticed I am still getting a hot electrical smell even though all speeds are working but the smell only occurs on 1st and 2nd speeds.
My thoughts are:
The blower is perhaps partially seized and so the extra load is drawing higher current so creating heat in the wiring.
MORE LIKELY THOUGH.....as it only happens when used on 1st/2nd speeds..the step down RESISTOR is getting hot because of this extra load from a partially seized motor!
So...where is the resistor? do you think it needs replacing at the same time as a new motor OR do you think once the new motor in replaced the load will drop and thus the resistor won't overheat.
Just preparing myself for what parts to buy.

IF I remember correctly (t'was a long time ago) the resistor is located next to the terminations to the motor itself - looks like you're going in there anyways so I'd lube the motor and run it for a while and see how the resistor fares. Resistors shouldn't too cost much anyway.
