Blower Motor Replacement - 1990 740GL Wagon
Picked up a blower motor today from NAPA (BK 6552407) hoping to replace a recently failed one in my wagon.
When I got the old one off and compared the two they look more than a little different (photos below).
Anyone else have a similar experience, advice or any ideas on where I can pick up the right one?
Thanks,
Ian

The label on the old one reads:
Valeo
A 03/15/02
22137253
12.0V 48293

it appears Volvo no longer sells the originals.
IPDusa.com sells this one,
Heater Blower Fan Motor
fcpeuro sells that one and 2 others, the cheapest of which looks kinda like that one you got
Volvo 740 Blower Motor Parts | FCP Euro
I'd probably get the VDO
oh. it looks like 740 blower motors changed after 1988, per some info on the fcp site, the single wire version might be for 1983-1988, while the two wire versions are for 1989+ 740 and all 940.

you might clean the contacts and connectors on the resistor pack thats stuck on the outside of the air ducting... I'd probably replace it if it looks like its too baked (often old dying motors will overstress the R-pack). the various pins and resistors are used to slow the motor down to different speeds (on my 92 740 there's 5 speeds). I don't use speeds 4 very often, that likely puts the most stress on the resistors (speed 5 bypasses the resistors entirely, speed 4 goes through 1 resistor, speed 1 spreads way less current through all 4 in series)

Just had the new fan delivered. Looks just like the old one. The directions, however, are telling me to use a hacksaw and the provided adaptor ring.
In my opinion, if it fits, you don't cut or modify anything... unless, of course, there's a good reason to.
Is there any reason to not just use the existing housing unmodified?
Deep thoughts.

ummmm, if it fits, use it as-is.
i wonder if those instructions aren't confusing the older version for the newer?
the picture on FCP's website of the VDO fan *looked* just like the original 'new' version, while that other one they had was 'adaptable' and had an adapter ring or whatever.

A funny thing happens when you plug the fan in the wrong way. Since it's DC, it'll spin the wrong way.
I pulled the panel and saw that that's exactly what I did (The coupling on the FCP's VDO fan can be connected either way).
So, now that it's spinning the right direction, it works like a champ.
