So my blower fan went out on my 90 camry. I bought a replacement from the junkyard, and it didn't fit, the lip of the motor left a gap so all the air came out down by the motor, very little out the vents. Thinking the junkyard gave me the wrong part I bought a motor at Checkers, same problem. It seems that the motor doesn't fit flush on the housing, I can't figure out what I'm doing wrong. Does anybody have any experience with replacing blower fan motors? I'm at a dead end....

Thanks!
