02 Tahoe with flickering headlights
We have notice in the last couple of weeks that the Tahoe has devoleped a case of flickering headlights... The best way to discribe it is, they flicker similar to flashing the high beams ( the flickering fluctuates ). We have also noticed the the heater motor speed also fluctuates.
We live in Northern Michigan ( gotta love the Winter ). These problems only happen when the "Hoe" is cold. Once it completely warms up the problems go away.
Anyone have any idea what the problem could be ? Alternator ???
Tx for any & all help
