Anyone have a good photo or diagram of the mode door actuator and the cam and rod assembly on an 02 Dakota, single zone HVAC box? This unit has the mode and blend actuators on the driver's end of the box. There is a round cam wheel with grooves that actuate 2 separate levers for doors. I tool mine apart and now cannot get it back together. Help please!

Not sure if this helps... better than nothing I guess. Note what it says in step 5.

MODE DOOR
There are four mode doors one defrost/demist door, one floor door and two panel doors. All mode doors are driven by one mode actuator that is attached to a mode cam. Each panel door is driven via a linkage to the panel door shaft. The panel door shaft is connected to two panel levers that are interconnected and driven by the mode cam. The floor door is driven by a floor door shaft that is attached to a lever that is driven by the mode cam. The defrost door has a lever that is connected to the mode cam with a linkage. All mode doors are serviced as part of the HVAC housing and are not available as separate components.

Bumping an older thread because i let the mode actuator lever fall loose.....now i'm having trouble putting it back.
Oh well, my ac is working again. Worst case is i set it up for the summer and leave it alone.
and i couldnt get the link to work....i think i found it......
Just had to take out the [blend] on the link.
