From the 7xx/9xx Maintenance FAQ:

Replacement Blower Motors for 7XX pre-1990. [Note: Latest comment: There is no GM part equivalent to the Volvo blower motor for

1990 and later 7xx/9xx. The part may work fine in an earlier Volvo. The Volvo replacement part has been redesigned from the original 1990

part so you can't just get the blower motor assembly - you need the assembly, a new plastic mounting plate, and according to parts person,

a new resistor added to the switch.]

[First comment: GM mid-80's blower motors for AC Chevy Citations are exact replacements. Also: look for an '81 Delta 88 w/ air

conditioning blower motor. Also: The replacement for the 760 series fan motor is a standard GM fan motor. The NAPA part number is

455-1076. Also: fan motor for a '87 760. The clerk responded, $57.94 and we'll have to order it. Then, I said ok, Try a '83 Chevy Impala with

AC. In stock and $17.99 with lifetime warranty.]

The reason the original fan failed became quite apparent in today's rain. Water showed up around the new fan. Apparently the 740 has a

tendency to leak on the passenger's side with the water ending up in the plastic basin that the fan sets in. [Note: See Volvo TSB for a fix for

this problem.]

[Second Comment:] After posting an e-mail question regarding heater blower motors on the Swedishbricks mailing list, I received a

response from Bill Cheb that he rebuilds heater blower motors and adds ball bearings which should add an extra several hundred thousand

miles to their endurance. Bill was easily accessible via e-mail at bill.cheb@ualberta.ca. He promptly responded with information on how to

order. His delivery was prompt and included detailed instructions on how to install the new motor. The total cost including delivery was

$125.00.
