What would cause the heat in a 1991 Buick Skylark not to get warm?

Thermostat possibly stuck open. Another possibility is the heater core is clogged. I would recommend you perform a complete cooling system service. Drain and flush the system with the heater set to high. Replace the thermostat, and install a 50/50 mix of coolant and distilled water. Bleed all air from the system.
