PONTIAC GRAND PRIX HEATER PROBLEM

2001 Pontiac Grand Prix

Hey, I just got my balancer fixed the other day and right after I got my car back it started acting weird. It has done it twice now. When I am driving down the road my heater goes from really hot to really cold and my temperature gage starts acting really weird and it will go all the way up to the top and my car will start cutting out so then I shut my car off and turn it back on after a few seconds and my heater works fine and it drives fine then after a while it starts to do it again. Do you know hat the problem could be? I checked the antifreeze and it is fine.
