The heater in our 04 always seems reluctant to work in the early fall. After fiddling with the controls it finally starts to work with out any further problems untill the next fall. Anyone else have this annoying problem?

I was thinking the same but didn't want to say he had crud building up, but that's what it is if that's what it is, eh?

If it's crud then you might be able to remedy it with a lubricant (WD-40 or similar) or cleaner.

It seems to be the pulse motor that moves the damper door. I removed the lower kick panel on the drivers side to get access and hit the back of the motor with my screwdriver to get it to start to work again. If this continues I will replace it.
