[200q20v] Re: Sheeza HOT, Sheeza COLD cont'd

[Gary Martin]

Well, I think (hope, fingers crossed) the problem is solved. After running
diagnostics and finding no abnormal codes, taking out the servo motor and
looking at it. Looks OK, moves the flap OK, I put some Pro Gold contact
enhancer on the servo motor connection plug. Took the car out for a drive,
and all seems good. As indicated on Chris's web site, this connector seems
to have been the problem. Thanks for all the responses.
