I replaced a couple of parts last night. My front license plate bracket was tweaked, so this nOS beauty was installed after it was given a couple of coats of SEM trim black..
I had a blower performance issue, and an annoying rattle under the passengers side of the dash. The culprit was the lower A/C duct, as is typical with many of these 2nd gens..
I used the Parts Place repro duct, which is a very close, good fitting part.
The original part was not a good design to begin with. It is a fragile, thin wall plastic, with not many mounting points.
