You have to check all associated fuses and relays then check power at the blower motor resistor located under the hood on the passengers side on the heater a/c plenum against the firewall under the rear coolant hose going into the back of intake. ..do the tap test and see if blower cones on

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.

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).

Heater and airconditioner control on mercery grand marquis


If the fan will not run on ANY speed in your Grand Marquis, the problem is most likely NOT the control switch.

Check for power and ground at the blower motor connector. If power and ground is present, replace the blower motor. Otherwise, the problem is most likely a failed blower speed control module (VERY common). The blower motor speed controller is located in the A/C evaporator housing just below the heater hoses.

Note: It is also common for a bad blower motor to CAUSE the controller to go bad. You MAY have to replace BOTH.

Hello
Before doing anything check the fuse box. If all the fuses are ok - this means you have to fit new heating element.

Blower stopped working on my 2001 Mercury Grand marquis


Check the fuse first. If the fuse is good then either the blower motor or the blower motor resistor pack is defective. Check the blower motor by applying 12 volts directly to the motor. If it runs it is good and most likely the resistor pack is bad and needs replacing. it can also be the blower motor speed control but rarely do they go bad.

Check blower control switch is operating OK,
Check relay controlling fan is operating OK,

Check blower motor ground connection is not missing.

Mercury grand marquis,ls,2001. the ac blower is not working. I jumped the fan direct from the battery and it works. How can I by pass the climate control and install a manual switch. I beleive the climate...


Have you checked the fuse under the dash. You can run power directly from the battery as you did to test the blower just make sure you use a high amp rated switch and make sure you install an inline fuse rated no more than ten amps if you use say 14 guage wire. Let me know how it goes good luck.

Heater and ac not working, nothing blows out


Sounds like the fuse to the blower motor (squirrel cage fan). Check the owner's manual for the location of the FAN fuse.

Heater wont come on


Your EATC control module is bad. 100% all Grand Marquis and Crown Victorias with electronic ac controls.
I rebuild them with lifetime warranty.
