Ok you have a bad blower speed controller if you have power to the motor.
It is located under the hood in the heater housing just below the heater core coolant hoses.
You will have to drain coolant.
Remove the nuts holding the Vapor Management valve and set it aside.
Remove coolant hoses to heater core.
Disconnect electrical connector to the blower speed controller,remove screws,pull it out of heater housing.

needs re-gassing because one line should be hot (feed) and the return cold , This is a specialist job do not attempt to do it yourself because its extremely dangerous with very high pressures involved

The blend door is stuck in cold position. That usually happens because the blend door actuator has failed.

You will need to test and replace the blend door actuator.

To replace the actuator you will need to take apart the dash and remove completely the instrument panel,d isconnect the connector, remove the four screws, remove the temperature blend door actuator and replace it.

The replacement is not a job for beginners, since you have to take apart the dash to access the actuator.

Regards.

Hello. The most common cause for no heat is the thermostat. This is a quick and easy repair. Go to any autozone or similar parts store for the part. They may even install it for you.

1998 mercury grand marquis heater doesnt work only cold air comes out the air cond works fine the enginecoolant is new, the engine doesnt overheat.


Either your heater control valve is not properly operating or your heater core is clogged. Locate the heater control valve under the hood, should be close to firewall on heater hose, have someone adjust temperature from hot to cold and see if you can see the heater control valve operating if so replace the heater core, if its not doing anything replace it(heater control valve).
