cars that are equipped with ac are supposed to run when the heat selection is on : max a/c , a/c , mix or defrost. the ac pump dries the air that flows through it which helps to clear the windshield and also to help to feel cooler in the summer . i have pulled the plug on the compressor before to turn it off during the winter months but it is just fine to run

Also, heat settings keep the compressor running to prevent it from seizing. The number 1 cause of compressor failure was due to lack of use during the long winter months.

The oil pump inside the engine is probably busted. If you start and run it you will probably ruin the engine. Probably $100 to fix now or $7000 to fix if you ruin the engine. Don't drive it or run it any more.

How do you determine what the problem is when the heater for a 99 Chevy Blazer won't heat up but stays barely warm?

Thermostat stuck open or heater core clogged. I had a similar problem in feb.2005 with my 1998 S-10 Blazer and it was due to the Dex-cool had turned to sludge , and that caused lots of problems. The first thing to do is after the engine is warmed up, feel the heater hoses going into the heater . if they are hot then the problem is in the heater, probably just adjustment or fuse. If they are just warm to cool then the answer is in the engine, probably needs a thermostat. answer can also be the temperature control switch in dasboard of car
