I have a manual that I downloaded but I can't find what I'm looking for on it.
I tried a second A/C control unit but the air only blows out the front vents. I'm guessing it's the vent mode servo motor not opening any dampers. I can't find where it is.
Does anyone have a pic/diagram of it?
And does anyone have a procedure on how to get to it?
Thx

 

For anyone who was interested, it's a FU**ING nightmare to get to! You have to disassemble the damn car to get to this one servo!

 

Just now seeing this. Yes, the servo in that location is a complete PITA to get to as you've found out: total dash-out procedure. One of the worst jobs on these cars.

Since you've got it all disassembled and are looking into getting a replacement, check out his DIY video showing how to clean and service the servo. Regardless of whether or not you clean your original one, find a working used one or manage to find a new one it may come in handy.

The part and guide are based around a servo motor unit in a 90's GS300 but the general cleaning and service principles should be the same and applicable to our SC HVAC servo motor units.
