as mentioned before the temperature blend DOOR is not working...this is a step motor that has 5volts dc applied to it and this motor moves this door to allow air to pass thru the heater core....this door can stick,,,maybe is loaded with texas dust....out here where I'm at it would be leaves,and pine crap...

so this means you must open the air box under the dash directly above the center trans hump,,,this is where this motor and then the internal door can be checked out...


you got filters in that air box,,,if not all the greater chance for this to occur..................

whats the best way to access this? do i need to start removing the dash and what not? or can i access it like i did the blower resistor.
