Well here's the latest: Got a working motor and resistor in there, and changed the no. 31 fuse, and what happens, now that I have power to the motor, it comes on for about 1 second - just a quick puff - then shuts off. I even tried my spare ECC, and same thing. Since the generic scanner won't read t...

Thanks J.A., much appreciated. I had the battery off for a good while as I mounted the motor back, and it did sound like it was trying again. Last time this happened, I got a used motor and resistor and that did it. One of the fine retailers who have a banner on MVS - Erie - had them both, so I orde...

Okay, pulled the motor, and got a surprise - a plastic bag had gotten into the motor and was all wound around the spindle. Unfortunately, even after removing all the plastic and resetting the codes (via battery disconnect), still nothing. Going to keep after it, it's COLD here.

Thanks again Jimmy, I really appreciate it, and that gives me a lot to investigate. Like most things Volvo, it's a complex chain. I'll have a go at it, and post the results. Wish me luck!

On ECC the transistor power stage (referred to as resistor) will shut off blower if the starting current is too high. Tight dry bushings in the motor will cause this. Before you spend any real money, disconnect battery and then remove blower and use WD-40 or other spray lube and spray into ends of ...

Thanks DJ, no I didn't. I don't where I would find that (searches come up 0), but I'll dig around the site some more and see if I can figure it out. Thanks again.

Hello all, I've been searching MVS for this exact problem, but haven't seen it addressed. I replaced my blower motor and resistor - with the help and encouragement of other MVS members - with used ones about 1 1/2 yrs. ago, and all was well. Now just when it gets cold here in New York, poof, no blow...

Hello All, I heard the blower motor going (dying) for a couple of days - didn't realize that's what it was - then; no fan at all (though it did seem to sputter back on briefly.) Though a relative car-repair novice, I'd like to give this a shot. I'm assuming ( I know, that's dangerous!) I'll be able ...
