I knew almost none of this. For some reason this car still gets my goat! But I must start. I thought these were completely electrical. My vents do not work right, so that is where I will start I guess. Could I just clamp off the hose to those and go for a drive?
The kick down does not work. That is another on the list.... And it keeps growing. Do not know If I can keep up between this and the f-series truck. But I will try.

I will also do more searches.

Thank you.
Doug
