Not sure how relevant this is, but I’ll throw it out there anyway ...
The HVAC blower motor on my ‘99 also got squeaky and annoying, so I replaced it. The OE replacement was really pricey, so I got a Bosch unit that was cheaper.
I figured Bosch should make a quality unit, but it really sucked. It worked fine, but didn’t have all the extra plastic housing and sound deadening material of the original. It was basically just a motor and fan on a metal plate, so was noisy and annoying. I put up with it, but was really pissed every time I turned up the fan. Should definitely have spent the extra on the OE part.
