AC Servo Codes

[Ryan Snellen, CFP, EA]

I've read myself cross-eyed trying to find out how to replace the passenger side servo motor on my 04CTT. The symptom is hot air coming out of the dash vent on PX side, cool on the driver side. When I close the passenger dash vents, the driver side get hotter so the hot air is bleeding into the driver side (LHD).

My AC codes are:
2100 - Footwell flap
2101 - side blower
1810 - drive motor temp valve
710 - defrost flap
1299 - implausible signal

I have an Alpine 507 stero installed which is the cause for a few other implausible signals elsewhere so I'm less concerned there unless I am optimistic in my assessment. All I have been able to locate on the PX side is the bottom most servo; the footwell servo I believe.

I'm looking for direction on how to replace the servo, ideally with pix, and welcome any other feedback. I'm sure there is a link out there detailing this procedure but I have not gotten the correct search query to populate.

Thank you in advance.

Many times the servo is not bad but the foam from the flaps has deteriorated and jammed their movement. I would check that first then rest the codes and test before actually replacing any servos.
