SOURCE: how do you replace the

Hello, these are not too bad. One thing you can try first is to follow the wires from the blower motor to a connector on the Firewall. Tap this connector with the handle of a screwdriver and it may start working again. If it does not you can remove the connector and attach your new Blower Resistor switch to the connector. The Blower should work.

To switch out the part it is best to work on a cool motor. There are 2 screws on the part and about 90% is hidden inside the Firewall or ductwork. There will be a pesky water line coming from the top, back of the motor. Although you can undo the screws on the part without moving this hose, eventually when you get the part to a certain point; you can not clear the opening without smashing the Electronics.

Hence a cold engine will not lose as much antifreeze when this hose is removed because the "Air Lock" in the water system will minimize the mess and lost Antifreeze. You can also minimize the time the hose is off by removing the connector and screws from the old part, having the new part at fingers reach and tighten the new part after you slip the water hose back on.

I hope my solution is helpful to you.

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.

SOURCE: Mercury grand marquis 1997 temperature control

I'm not sure if yours is identical to mine since yours is second gen and mine is third gen, but with mine (1998 MGM), the heat was stuck on all the time. Full heat would practically cook your feet and you couldn't shut it off.

It was a servo/servo arm that controls the hot/cold mix door. The part was $15. The labor was $700. They had to take the entire dash out of the car to get at the part. Required two more visits due to a missed electrical connection to a daylight sensor and a vacuum issue that made the car stall when put into reverse.

My car had 150K on it at the time. Has 165K on it now. Still runs great and looks great. It's now my wife's auto and I drive a 2006 MGM.

I have no control over the ac/heater blower motor. EATC replaced no effect


Have you replaced the blower motor speed control resistor located next to the blower motor? If no that may be the problem.

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.

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.
