The blower motor on my '94 VR Berlina progressively got slower over a few months, started working only on high, then only intermitently on high, and then not at all. Aircon works well, so its a real pain having no blower in the middle of a Qld summer.
I think I have tracked the issue down to the blower motor itself. After stuffing around for ages reading about resistors/amplifers in the CC circuit, I spent 10 mins to take the glove box and kick panel out to measure the voltages at the motor power plug - they are about 5, 8 and 12-14V on low, medium and high settings. On automatic, with ambient temp at 31 deg the voltage is a solid 10V.
These voltages sound sensible to me for a '12V' blower motor, meaning the motor has some issue, like worn brushes, excess dust on the windings or something.
Any opinions before I spend hours trying to get the damn thing out? Please! Any suggestions for replacement/repair of the motor given I doubt I will want to be doing again soon?
