Heater problem
1997 Dodge Caravan 6 cyl Front Wheel Drive Automatic

I have a 1997 Dodge Grand Caravan. The heater panel has a driver and passenger setting for the heat to be cool or hot. The driver side is set to hot and works great while the passenger side is also set to hot but blows cool air out. Why does the driver side blow hot air and the passenger side blow cool air? Also how do you get the passenger side rear window to open? Where is the motor for this?

Suspect blend door
run a code check
Heater system is a blend air type. Outside air enters heater system through cowl grille and passes through plenum chamber to heater unit. Blend-air door, located inside heater unit, routes incoming air through or past heater core. Amount of blended air is controlled by temperature control lever. Air distribution is controlled by mode selection and blower speed.
