So, do we have cabin filters from the factory, then? I thought it was something that could be installed later on, but wasn't there when the car was new. If so, how do we access it? Is it from the outside on the passenger side cowl?
If not, then I am planning to take a look at the blower motor, itself. It seems like it's vibrating a lot when turned up past the 4th setting and hardly moves any air, to speak of. If it's not an OEM part, then I'll replace it with an AC Delco while it's out. Does anyone have a P/N for it on a '99 GTP with the dual digital climate control? My cost at the local dealership is $150, but I am betting it can be had for less somewhere else if I can get my hands on the right one.
