SOURCE: bad smell in air vent chevy impala

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.

SOURCE: 2006 Chevy Impala reduced engine power

best bet is to stop in at a Pep Boys, Autozone, or similar big autoparts seller, and ask for free trouble code scan, which should pinpoint area causing problem. If not obvious by codes, what is necessary to repair the problem code, get back to us with those codes and we will be glad to assist you further. Better this way, takes away the guess work, and saves you money, as well as getting it right the first time.

There's two knock sensor's, and there under the in-take, on top og the engine, when the knock sensor detects a knock on the engine block, it will send a signal to your compute to adjust the engine timing.

I have a 2006 impala. On the highway the dinging wont go off on the oil light. It says oil pressure low turn off engine but I changed oil today. The dinging just wont stop!! What's wrong??


Hi stevie, your Impala probably has a defective sensor, often called a "switch" that senses the oil pressure. The oil light and chime is a result from a false signal from the bad sensor.
But one cannot take a chance. If the sensor is acting properly, and pressure is low, it could really damage your engine to have low oil pressure and oil not pumping properly. Have it checked now. A new sensor should cost about 60 dollars & takes only a few minutes to install.

Good luck. i hope this helps. Please rate me a FixYa.

OK, bank2 is the side where the #2 piston is on. Usually its the pasanger side. To be sure open the hood and see which cylinder head is more forward than the other. the cylinder head set back is the bank 2 side. The knock sensor is located on the bank side of the block. You dont need a special tool. only a wrench. Make sure you clear all codes after installation of sensor.
