2004 grand marquis. Where is the blower control module located? (p/n 19E624)

    Are you asking about the Blower Motor Resistor? This regulates the air speed coming out of the registers in the cabin. It is located in the engine compartment on the passenger side "firewall". It hard to see due to hoses carrying coolant to and from the engine.

SOURCE: air conditioner blower motor resister on dodge grand caravan

in my 2004 grand caravan it's behind the glove box and left of the blower motor. disconnect the wires first then remove the 2 screws to pull out the resistor unit. First make sure you have removed the negative of your batterie. I had the same pm that prevented the blower motor to operate in any speed. I hope this will help

The blower speed controller is located under the hood on the right or passenger side on the heater housing just to the side of the heater hoses near the very back of the right cylinder head.
Yes that would cause the concern you are having.

Your P0700 code needs to be addressed right away. This signifies a problem with the solenoid pack, which is an external part that can be fixed for around $200 if you do it yourself, $300 if you take it somewhere. But a bad solenoid pack can mess up the whole tranny resulting in a total rebuild, which runs anywhere from $1200 to $2000 depending on where you go. 
Your P1770 error is a Clutch Solenoid Circuit Malfunction.  Definitely sounds like you have a solenoid problem.  Let me know if you have any other questions.  Thanks for ranking my response and for using FixYa!

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.

2003 grand marquis gs blower switch is a 4 speed. the first two LOW, and next position are not working. Is the switch module or the fan motor in the engine compartment?


There are resisters that controle the fan speed located in the plenum (its the air movement that cools them). They can be checked and changed out simply by opening the hood and locating the AC evaporatot housing on the firewall (passengers side).

Blower blows all the time. In June I had the part that directs the air replaced. Then the blower blew all the time and now it is doing it again 2008 Grand Marqui


If the blower blows all the time even when the ignition is off I would replace the blower motor control module( could be called the blower motor resister).
