I took my 2002 BUICK to the local JiffyLube for an oil/filter change.
After less than 5 minutes under the hood, the guy came back with a very dirty "cabin air filter". ( I had them replace it )
I'm somewhat surprised.... I've looked all over the engine compartment, and I can't find access to the filter.
The BUICK owners manual describes changing the filter, but it must be written in UAW code.... I can't make sense of the directions.
I'd like to do it myself next time. Any hints on where to start ?
