Heat "ON" = high pitched squeaks

JayGold · 12-08-2003, 09:10 AM

Just recently I started to use the heat on these cold IL mornings, I leave for work at 4:30am and let the car warm for a minute or 2 at idle. After about 2 minutes of driving I can set the heat to #2 and at about 4 minutes I can crank it to #4, the current issue I have is a major squeaking noise emitting from somewhere around the throttle body or stock airbox, but only when the heat is on.
I tested this at #1-#4 heat selection and it always makes noise from a standing start or when I rev match double clutch. When moving from a start in first gear the noise will emit from the beginning of clutch release to about 3 grand, then stop. It will not make noise in any other gear or on any gear change, unless I blip the throttle to rev match double clutch. It will make the noise at the blip.
I checked all my belts, its not them, I recently installed a new OEM starter, the noise is getting unberable, any ideas?

check for any pinhole air leaks? other than the belts, that's about all i could think of. did you try it with the A/C on?

Didn't think of A/C...hehehe

I'll give it a try when I get off of work. I'm going to reinspect the air box to throttle body seal, it could be that.
