HVAC Blower Motor Part# Needed and where to Buy
Hey, My hvac blower motor is dying. It only had 3rd and 4th speed, so installed a new blower motor resistor and now all 4 speeds work, but you can hear the bearing squealing in all 4. I already cut-out the cover to access it, and now you can really hear it squealing from under the hood. The only name and number on the motor reads "ITTA-Rochester 52477148 S". I'm assuming that is GM's number but I can't seem to find it online anywhere and GM most likely changed the number....
RockAuto has: ACDELCO Part#158746 {#52477152, 52498981} MOTOR,BLO(W/IMPLR) w/A/C MAN CONT(C60); INCLS ACOUSTICAL BARRIER
...I have production code (C60) on my Blazer and the control is manual, but not sure that is the right number, and it's way to expensive to guess at it. I only want to stick with ACDelco because I heard that VDO/Four Seasons/TYC and Continental motors (all available locally) are all somewhat noisy???, so I would rather pay the cost for ACDelco.
Any input on the numbers and where to buy would be appreciated.

So long as it shows the C60 RPO code, it should be a direct swap in. AC Delco's online parts catalog shows PN15-80466. 15-80466 lists as a kit which should include the acoustical barrier. Application range for 15-80466 shows as 99-05 which makes sense as well. When I do a search for 15-8746, it comes up as the blower motor only which contradicts RockAuto's description.

swartlkk, RA's also lists part number 15-80466, but because it didn't include the acoustical barrier in the description I was headed after the 158746 which did, so it looks like RA does have their descriptions crossed...
ACDELCO Part # 1580466 {Click Info Link for Alternate/OEM Part Numbers} replaces 52498982 MOTOR,BLO (W/IMPLR) w/A/C MAN CONT(C60)
...Either way, I just searched for AC Delco's online parts catalog and found it and see exactly what your seeing. Should of thought to do this first. There's a $37 difference for the kit, so it must have the acoustical barrier and the air cooling hose?? Headed after the PN15-80466.
As always, Thanks for your fast response.
