Ok so after the car warms up it blows out great heat.. Except at the feet Getting cold. Air. I would assume that there is some sort of vent sticking open allowing air from out side. But where and and how to fix is unclear
Thanks

It is probably the diverter for the floor vents. You can select the floor only, and determine if heat is coming out of them. It could be the vacuum motor, or the selector valve. Check for vacuum at the valve when floor/lower is selected. If there is vacuum, it is probably the vacuum motor. You can also hook up a vacuum pump to the hoses (tan and blue), and pump the line down to see if the motor works. I do not know which one is "floor/lower", but I would suspect tan.

When you disconnect the battery, the AC reboots, and you need to run the temp up to the top and down to the bottom to calibrate the system.
