Does a 2001 have a cabin air filter, if so where is it? When the AC is on and the fan on high very little air blows out of my vents.

HELP!

 

Not clear what your question is but I'll take a stab at it?

Set the mode to vents and feet or even just vents, set fan on high little output. Even when selecting Auto little air output. I can hear the fan cranking on high and turning down when selecting down to low. The low output is for all dash vents.

 

ALL of your vents positions are VACUUM controlled. When you loose vacuum control the actuators don't have the ability to stay in one particular commanded position (they just flop to the center) and air exits from multiple vents and you loos the ability to control them.

The vacuum supply comes from the back of the intake manifold.

I agree.. NO C5 has any air filtering system.

 

Bill, that's exactly what it now appears to be the cause. When selecting just the feet output or the dash or the defrost all vents blow some amount of air. Bringing the car in Monday evening for a few days of maintenance and repair at our local Chevy dealership, we've added checking/repairing the vacuum for leaks.

On our list already for our 'new to us' 2001 with 48K miles:

• replace brake fluid
• flush radiator/cooling system
• replace both belts
• fix water leak on driver's door
• oil change
• replace air cleaner
• anything else we should have checked?

The brake pads were recently done, once home from the dealership, new tires all the way around.

Thank-you!

 

Clean the udders! 3 drivers side, 1 pass side!

 

And the AC drain on passenger side engine fire wall.

 

 

My dealer found a previous battery leaked and damaged the vacuum hose below the battery box. Hose has now been replaced, the vents work as intended and the idle speed increased from 550rpm at full operating temp back to the factory setting. BUT the leaking acid also damaged the frame coating and we now have surface rust and bare metal, any suggestions?

Thanks, Kevin

 

Pull back/remove everything from the frame and area where the rust exists. Scrub it down with a small wire brush to remove the heavy rust/dirt/paint. Wash the frame with degreaser and rinse well. Spray an acid detector/neutralizer spray onto ALL of the wiring/frame and components! Get rid of all the acid. Rinse well. Spray the frame with a rust converter and let the converter cure as per the can instructions. Prime the area and then paint it with a semigloss black epoxy paint. or enanal paint.

 

I looked for one too but I figured out the C5'S don't have a factory filter.
For about $6.00 you can make one that is better than nothing.
Pop the hood and clean off the grill work on the cowl. I took mine off to repair the windshield washer hose and while there I washed the whole area. After ait drying I used a air compressor blow gun and made sure that the udder's were clear and that no large debris was in the air intake area.
Put everything back together and here's the easy part. I bought a Filtrete room air conditioner filter 15"X24" from Amazon. Now there are a few choices here, filters for removing smells, toxins and the one I got which is for microscopic allergens, dust and smoke particles, mold spores, dander and pollen.
To install the filter you can cut it in the shape of the grill which is a bit like a triangle. I lifted up the weather strip on the cowl, insert the filter edge under the lip and reinstalled the weather strip. I carefully folded the filter in the shape of the grill with it overhanging a inch or so on each end and layered the whole filter covering the grill completely. Press it gently into it's new home and it'll stay by itself and completely filter any air coming in this way. I've noticed no difference in air flow with the exception of it being a little bit quieter
I'm not sure if it's doing as well as a factory filter would but the last one I changed on my daughters Buick it looked very similar to my home made one at a third the price. Time will tell just how much junk it's keeping from going into my lungs.
