What's the easiest way to fix the heat 'blend' motor?

Bretb: I didn't pull the dashboard apart--I was able to pull of the blend door actuator from the driver's side of the heater control console--my head was wedged in between the dash and brake pedal. The plastic piece that slides on the actuator shaft (that turns the blend door) was broken. I went to a junkyard and got another piece. It works most of the time but the calibration seems to be off--it works alright if I calibrate it when I start the van. So it's kinda fixed. I'm think that maybe I have the shaft in the incorrect position.

Nice work! Thanks for the update. These door linkages normally can only be installed one way, but anything is possible. I don't have a repair manual to look into this, but there may be a calibration procedure to reset the motors, other then the start up procedure it goes through.
