Heater problem
1996 Chevy Lumina V6 Front Wheel Drive Automatic 175000 miles
----------------------------------------------------------------
Heater blows hot & then cold alternately. Temp gauge goes to about 1/2 way then returns to about 1/4 fairly rapidly. heat goes back & forth with the guage. Both heater hoses are warm, radiator cap is very cold after 45 mile highway drive.

Yes, this will happen if the engine coolant is low, I would wait until the engine cools down overnight and then open system to check the elven, if low please use this guide to help find the leak.
