89 cadillac sedan deville not blowing heat !!

Yes, that would involve removing the old thermostat, installing a new one, and also a new gasket. What does your temperature gauge indicate when the car has run a while and is warmed up? If the gauge indicates that it is running on the low side, or never seems to warm up, it could indicate a thermostat stuck in the open position, which will prevent it from reaching operating temperature, and would explain little or no heat situation. 1st, tough, check the coolant level. If it's low it could cause the no heat problem.
