So I commute three night a week with a group of four people. One of these peeps is a female with a 95 up or so Olds Bravada...basically a dressed up Chevy Blazer.

Anyways...her heater has some issues and its really cold here.

When the car is idling in park, not moving, the heater blows out COLD air....when its moving the heater works OK...but not as hot as it used to be. Any thoughts?

I didn't look at it last night b/c it was so cold and we don't get back till midnight...I'm thinking maybe a low coolant level? But the engine temp is around 200-210 all the time...Blower fan works fine.

How about it?

The coolant level is low if you get no heat at low RPM and get some or off/on heat at higher rpms.

It is a restricted heater core. You can flush it with a kit from prestone or replace the core. If you want I can get the numbers tommorrow for the prestone kit that GM calls for.
