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.

I have poor air circulation for my 2001 Mercury grand marquis. I only get air from one dash vent. the blower goes up and down but even on high it seems like it is medium


well, if nothing was disconnected on the ducts and the selector works fine , my guess will be that you have a nest in the fan it self, take it out and clean the nest so the fan can blow full amount of air. good luck.

2001 Jeep Grand Cherokee Heater


the heater core is removable from the climate control unit. The climate contriol unit has to be removed to replace it. The A/C system must be evacuated and lines removed as well as the dash, to access the climate control unit. The steam is coming from a leaking heater core.

2003 grand marquis climate control fan speed runs only on high


Its probably going to be the fan resistor. Most times it is on top of the fan itself but could be elsewhere behind dash. 90% sure thats your prob though.

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.

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.
