Why do my 2007 chevy impala front speakers partially work?

pop out the center trim piece with a flat head screwdriver. Center dash piece may be brushed aluminum or wood grain depending on trim level. It should pop out easily working all the way around it. Then radio is held in with 7mm screws.

It is not fixed by an aerosol or scent additive to the air in the cabin. It will only mask the smell for a period of time.

Your cause is the air filter for the A/C system. You can buy a new one at local auto stores.

To replace it, you will need to open your hood. On the passenger side of the car, look just under the windshield at the trim panel under the wipers. You will see several tabs holding down this particular side of the trim piece. Using a phillips head screwdriver, gently rotate the screw pieces out of the tab holder (if this doesn't get it, you'll need to use a small flat head in unison to apply pressure to the screw to come out). There are 3. Once these are removes, gently pull the hood rubber gasket seal up and place out of the way. Note: you won't need to remove it from the car, just enough to clear the trim piece. Remove the trim and you will see a filter. Remove the filter and replace. Installation of trim is reverse.

That will fix your mildew smell from the vents. This WILL NOT fix a mildew smell if caused by interior mildew.

Note: The directions to change this filter are also found in your Owner's Manual if you have it. It is a simple procedure and should take about 15 minutes if you are taking your time.

Thanks for the inquiry.

I would start with fuses then look to getting a new stereo only thing ir a n aftermarket harness for that car runs about $150 bucks
