OK i know this might not get that many looks but................ There is a sound coming from inside my blower. it is kinda like a grinding sound. I have had the S/C on for almost 2 weeks, and i have yet to realy get on it. the car has not gone over 5500RPM. ahhhhhhh it realy pisses me off

 

So it is different than the whine that is supposed to be there?

 

yes it is different then the whine.

 

I don't know how many people here will be able to technically help you with this, its largely uncharted territory. I'd get that car back to the install shop immidiatly for diagnosis!

 

The most common SC noise problem is the idle pulley due to small bearing and high speed. Over tightening the drive belt could also affect the nose cone bearing on the SC and/or the idle pulley. You can pin point the noise by using a stethoscope.

 

Paging Dr. JTso ...

 

No kdding, it's one of these.

 

If the sound is loud enough to hear from inside the passenger cabin, wouldn't listening to it with a stethoscope cause some potentially serious ear damage? Are those stethoscopes somehow muffled or something?

 

The stethoscopes are usually designed to amplify the sound. So it can get pretty loud but it does the job to locate where the noise is coming from.

 

ok well i pulled the blower off and yeah, the fins are rubbing. i called comptech about it. Now i am just waiting for them to call me back. man this sucks that my car is down i hate not having a car

 

Did you install this yourself?

 

i had a shop do it and i helped. my boy owns a shop and he said i could help.

 

ok i got off the phone with comptech and i have to send my blower in to them and they will send me a brand new one. HOLLA!!!
