As rediculous as your first post was (this is my very first post on here) it did recieve alot of response...
Anyhow I would think the lights have nothing to do with the seat heater not functioning... I just purchased an 03 Yukon Denali and mine does not really work the well either.. The back part of the heat works but the A$$ part doesn't seem to heat up like the passenger side. I would think the element(s) have gone bad, but I really don't know...
Good luck with the problem.
