Heated seat issue with remote start.

[justbabs]

My 2011 Tahoe has heated seats. The driver's seat doesn't work, consistently, with the remote start any more. It was having issues with manual operation. It would go off when I shut the door. I replaced the switch in the door, and it works fine manually, but still doesn't work with the remote start. The passenger seat works fine with the remote, as well as manually. I have the passenger seat out right now, and the connections don't appear to be burnt, or corroded. I saw somewhere in another post to check that. How would I diagnose, or test, to see where the issue may be?
