My drivers seat seems to intermittently will run the heating/cooling mechanism. Sometimes it soundslike the fan kicks on and then shuts off after a few seconds. Sometimes nothing. When I select it, I hear a 'click', not sure where. The passengers seat runs consistently and I compare the two it is noticable heat/cool difference.

1. This shouldn't be battery related. Brand new Interstate AGM in it, and then I keep it on a charger almost all nights.
2. I have filters on order for it, but doubt that would cause the issue.

Any suggestions? Are there any wiring diagrams for it so I can see if it is a power/signal issue? Are the passenger/drivers assemblies interchangeable (if so I would swap them to see if it is the mechanism in the seat).

I have a couple of nasty work reviews this week, so my plan is to try and look into this next weekend.
