I have been looking and studying the system that is on the car over the past few days after hurting myself weight lifting and not being able to do much of anything else. When I replaced my vacuum foot pod, I pressed the floor button on my climate control module (and every other button for that matter).
NOTHING HAPPENED!
There was no change in the airflow, it still just came from the side vents and the defrost. So I tried pulling on the footwell flap, because I can just get my fingers into the vent. I have a very strong vacuum holding it in place.
That being said, it may be possible that I may not have a pod problem at all, it may well be my climate control module.
I plan on taking the car to a yard and pulling several of the modules I had found earlier.
Just how common is a failure of the push button console?
