[W126 Coupe] Squealing N3 module

[Dick Spellman]

Hi Dan:

I looked into that very item sometime back.  It looks to be an 
unpleasant task where it involves the A pillar cover and headliner up 
under the passenger sunvisor.
I guess if I were to decide to go there I'd considered running a short 
piece of electrician's snake (taping the end loop to avoid hooking any 
low-voltage electrical wires) from the courtesy lamp opening over to the 
A pillar and pulling a new tube up the A pillar (cover off) from under 
the dash opening along side the glove box.

Dan, the big question is, do you believe there is enough of a 
performance gain in the ACC by having a functional draft off the 
aspirator tube/blower to warrant the effort???
