I don't think my problem is the Blender Door. Please help.

I have a 98 Eddie Bauer and last year I started having trouble with the heat and a/c. When I turn it on heat, cold air blows until I hit a bump in the road or come to a quick stop, then it will go to heat. Same thing for a/c. It blows hot air until I hit a bump or come to a quick stop, then it will blow cold air. When this happens I can hear a suction noise, like something is closing off under the dash. Please help. I looked at the blender door fix and this doesn't seem to be my problem. Any suggestions would be appreciated.

thanks

It is your blend door. The door is opening and closing on it's own when you hit a bump. The suction noise occurs when the door is switched from hot to cold. It happens in my 98 Explorer.
