Dashboard Removal / Stepper Motor Linkage Replacement
I have the common knocking sound from the AC stepper motors. This one is in the CD changer area, it's maybe the one by the right vent in the center nozzle.
How many stepper motors are in there? Mine is a 2002.
I tried the resynchronation process but it stays ON...
What are your suggestions? Parts were only $6.37 for the linkage and I'll hate to pay $600 for labor...
Thanks for your input - Carlos
I'm assuming it's the footwell flapper since that seems to be the high failure part. I could live without heat going to the footwell but the noise irritates me. From the diagrams linked by BKLYN C it looks like part #310 is the motor in question as it is attached to the left 'legroom' vent. From this link http://www.kotikone.fi/eerola/auto/d...ash/index.html it doesn't look accessible through the center vent.

my stepper motor is M2/8, most likely will need to take the dash off to get at it from the top. urgh!!
