I experienced blower speed variations that were caused by an overheating FSR that melted the harness connector. Depending on ambient temperatures and electrical load through the connector, the voltage varied to the motor as the connector resistance changed.

And it's only that subtle turn left that does it. No other turn or spot on the steering wheel (right or left) can I get it to be repeatable. Agree on the gyroscopic forces.

I'll keep an eye on it along with other suggestions. Might change FSR to eliminate that variable.

Getting worse now. Sounds brutal and mechanical (it is definitely the fan). I'll try to remove the intake plenum from the engine side to see if I can lube the bearings. I have it booked at my indy for Aug 15. Book says 6h. We'll see

As noted in the thread, probably not FSR.

For the record though, I'm not sure when the FSR was fixed, but my 2004, 10/03 build, went through two in the first five years of ownership. Still on the third one I got on eBay. Looks like LVP's is a 01/04 build.

"While they're in there" the FRS will get replaced. I'll shoot some grease at the bearings this weekend and see what happens. I'll keep you guys posted.

Thanks!

Update.

Indy did the fan and FSR yesterday. Pretty much spot on to the 6 hours for the entire job. He did remove the steering wheel (which was ok, seeing as when I put it on last I was out by a tooth and it was REALLY annoying me ).

No amount of lube would have fixed the fan. The bushings were worn right down to the holder and wearing it out. Hard to see, but the front of the pics show some bushing material, but at the back there is none.

Works beautifully now.

Cheers.
