I have another question. The vent control module obviously isn't working. Air comes out from the defrost, the dash vents and the floor. I have the new control module. But I have been unable to find any information on it. Where it is located or how to access it. Can you provide that information?

So, these are a vacuum controlled vent system and what happens is the HVAC system loses vacuum because the small vacuum line under the hood falls apart. Here is a guide to help you fix it and I have included information on the location of the blend door actuators.
