My heat, when on, fluctuates hot then cool. Anyone know why this may occur? Maybe heater core going bad? I'm not about to take it to the dealership and then they tell me "oh there's nothing wrong" when in fact there is. Yeah I have the extended warranty but if they come to a conclusion that nothings wrong then I pay for the labor fee. "F" that! Been there done that! What do you guys think??????

What temp is it set at ? When it reaches a set temp if not set at max it can blow cool air to maintain like 70 degrees once it reaches that temp. Or if set to max then it blows cool air I'd say check the antifreeze to make sure level if not low the could cause problem your describing also.
Could be one of the vents behind the dash not opening all the way and allowing cool air to mix with the heated air, just a guess.
