2000 Chevrolet Impala heater direction not working. Control panel is new. Doesnt matter if you put on deforst, floor or face it blows out floor. I was told there is a servo motor that is located in the dash and very difficult to get to. Where can I get instructions on replacing this part?

The 2000 HVAC is actuated by vacuum. Check under the dash for disconnected, damaged, or broken vacuum hoses. I have attached a list of where the vacuum hoses go to help. Let me know what you find.

PS: It isn't real easy to check these. They are up and under the dash. If you are lucky, with the engine running you may hear a hissing sound that would indicate a leak.
