Hey guys, new member, Ive been looking for an automotive AC forum for a long while, stumbled on this one. I will have MANY questions down the road, maybe not so many after I read alot of stuff here.
Anyway something Ive been wondering about for a while is... Is there anyone who makes a blower fan motor/ fan assembly that is quieter than the original? Is there anyone brand that is quieter than stock?
My fan blower seems to make alot of noise, especially when its turned up on higher settings. Part of it may be from the sound of air rushing through the plastic vents, but some of it is the fan itself. Its not like its making any horrible noises like its getting ready to fail, I just want as comfortable of a ride as possible and elimating as much noise as I can helps add comfort. Ive got all kinds of sound deadening products that I am preparing to add to the body and interior. If I can do anything about the fan it would make things extra quieter. Ive thought about using some of my second skin audio damplifier sound deadening mats and sticking them on the plastic vents that run throughout the dash to see maybe if it kills some "reverberation" of the fan noise through the plastic.
Anyone ever do anything to make their system quieter?
BTW the car is a 94 chevy caprice

A clean system is much quieter than one coated with all kinds of road debris, the major noise maker is the squirrel cage blower wheel itself. If you motor shaft is bend or worn, the cage can be rubbing on something. Debris builds up on that cage causing a misbalance. On recir, that cage can pickup of gum wrappers and other nasty stuff from the interior of the vehicle. Clean it up first, make sure the motor is in good condition, very typical motor problem is that the shaft rusts to the bronze bearing turning that bearing in the sheet metal housing, that also makes an unpleasant noise.
How much noise is your fan making? I have a '96 Impala, and unless it's on the 3rd or 4th fan setting, there's no noise from the blower.
But, if you are taking about the sound of the air rushing out of the vents on high speeds, there's not much you can do about that. A brand new Cadillac sounds like a hurricane when the a/c comes on with 110* interior temp.
