Check you heater blower motor.
This sounds more like the common blend door problem on this model. The plastic door is driven by a DC motor that is geared too strong for the application. Over time the motor will overstress the door and break the connector. The same plenum box is used on the F150 and you can find information on the problem by searching for that model also. There is a video available on YouTube showing how to diagnose and repair the system. It is an expensive repair at the dealer, but you can repair it yourself with minimal skills. You can follow links on my bio page for pictures and additional information on how to diagnose and repair the problem.

I am having the same problem. The dealer wants to charge 100.00 to fix the one post which isn't horrible but I would rather have metal parts so that it doesn't happen again. Do you know what the site is for the aftermarket kit?

This could either be due to the age or the materials used to make the water heater or the fact that the water heater has not been installed with vacuum breakers causing the geyser to collapse from the inside-out due to incorrect atmospheric pressure within the water heater
