CHEVROLET IMPALA COOLANT PROBLEM

2008 Chevrolet Impala • 15,200 miles

The heater is warm only when the car is in motion. It does not warm up the car when idling, and the air temperature cools down when I stop at a light.

It could be a few things but I would start by check the coolant level (when engine is COLD).
If it's too low add some and see if that fixes your problem.
