Question
QUESTION: The vehicle is a 1997 dodge grand caravan. When I go to turn on the heater, the passenger side vents blow warm air, yet the driver side vents and the two above the radio blow cold air. How do i get all the vents to blow heated air?

ANSWER: Hi Raymond

your heater door or actuator are bad.  You must removethe dash to get to them.  Before you remove you must chek to see which is not working properly.

QUESTION: Okay..Thats a start, before I start pulling the dash out, could you help me pinpoint what i'm looking for via a diagram or explination where I can find the door/acuator, what it looks like? I appriciate the help.

Answer
You can clamp the heater hoses and see if the system cools better.  Once you determine that it is cooling then you can go inside and under the dash check your actuator motors.  If when you clamp the hoses you are still cooling bad then get the pressures both high and low and let me know.
