So seeing as weather here in Wisconsin is beginning to get colder the heat problem is becoming more of an issue. Heat works, damn well in fact. Blower settings 1-3 work, 4 does nothing whatsoever. The blower produces a constant clicking sound, not obnoxious, but constant. My question is, is it difficult to replace? And what is the difference really between going with OE vs aftermarket on this part?

Car: 1987 Volvo 740 Turbo 2.3L

OE:
1985-1988 Volvo 740 Turbo Heater Blower Motor | Volvo Heater Parts

Aftermarket:
Everco/A/C Heater Blower Motor (35334) | 1987 Volvo 740 4 Cylinders 8 2.3L FI Turbo | AutoZone.com

 

Both of the blower fans that you have listed are made by Four Seasons so one can't be OE and the other aftermarket. If Four Seasons is OE, which I am not sure, than I would go with the Autozone one since it's cheaper and appears to be identical to the FCP one.

 

Oops I mistook Everco as a different brand. Thanks for pointing that out. & alright, Will do. Car was equipped with A/C but was later removed, therefore I go with the no AC model?

 

The OE would last you longer but of course it costs more, the ones you mention are not OEs... The '87 740 takes a fairly generic motor, shared with many other cars such as Chevy Citation for one... Makes no difference whether you have a/c, (I know, they have to ask)...
