very hard to do. are you sure the door is frozen? maybe the duct is electricaly controled, in which case you have to find out why the control is not working. dodges are famous for the heater control contacts burning up. maybe check that?

Damper/vent doors/actuators difficult and expensive to get to. I have a defroster vent on my 1999 Silverado 1500 that wont open. May be a bad actuator, stuck vent due to filth or an small foreign object that has fallen down inside the exhaust windshield vent. I thought the problem was the temp/fan control panel on the dashboard which I replace for $149.00. I was wrong. Tried looking underneath the dahsboard to see if I could find problem. No way. Went to dealer. They want $180.00 to troubleshoot. Cost could soar up to $900.00 due to removal of instrument panel to correct problem. This cost assured because knowledge of the related problem with my type and year of truck. There is no easy way to see what is wrong due to compactness of components underneath the dash. I checked out other service centers, and basically the same.

If anyone has had experience in removing a dash and correcting my problem, I would like to see there suggestion on this site.

No you can't you must remove the dash.

The dash is held together by screws. Just take out all the screws in the dash, and also the ones in the pads on the window pillars on the side of the dash. You'll need to remove these to get the dash out. You can still get the dash out without removing the pillars, but you may damage your dash trying to squeeze it out.

You can do this without completely removing the dash. Just remove all the screws then remove the support bar underneath the passenger side of the dash. This should give you enough wiggle room to get the core out.

It is under the dash on the passenger side of the car. You can access it without removing any other objects.
