How to replace the rear blower motor - 2005 Mercury Monterey

Fuse for rear air ????? No air coming from rear vent's ? That would be caused by the HVAC blower motor not working . Probably not a fuse issue , if the fuse is blown you have a bigger issue . Fuse's don't just blow for no reason - electrical short circuit, too much current draw etc.. . More then likely it's a problem with the blower motor control module or the blower motor . Located behind the right rear trim panel . But go ahead an check the fuse anyway , fuse # 26 - 25 amp located in the underhood fuse / relay box . marked RR -BLWR/ 110 VAC
Auxiliary Air Speed
The auxiliary blower motor is controlled by the front auxiliary blower motor switch. If the vehicle is equipped with rear DVD (U32), the auxiliary blower motor can be controlled by the overhead console, vehicle entertainment system (VES). The front auxiliary blower switch must be in the AUX position in order to control blower speed from the VES. The VES will send a class 2 message to the HVAC control module requesting a blower motor speed.
The auxiliary blower motor control module is an interface between the HVAC control module and the auxiliary blower motor. The auxiliary blower motor speed control, auxiliary blower motor speed signal, blower motor speed control, and ground circuits enable the control processor to operate. The HVAC control module sends the commanded blower motor speed to the control processor through a 0 to 8-volt linear ramped blower motor speed control circuit. As the blower motor speed control voltage increases, the blower motor speed increases. The control processor sends the actual blower speed to the HVAC control module through a 0 to 12-volt blower motor speed signal circuit. The control processor uses the blower motor ground as a low side control to adjust the blower motor speed. The underhood fuse block supplies 12 volts to the blower motor through the blower motor voltage supply circuit.

possible bad switch... possible loose wires to the switch and or motor...

Hope helps (remember rated this).

The blower motor for the front needs to be replaced since the rear has its own

The rear blower motor on that particular vehicle is ground side switched, meaning there is B+ power to it all the time. A quick and easy test you can perform yourself is to determine which of the two wires to the blower motor is powered up. Supply a ground to the other wire and the fan should blow. If this is the case, I will bet the farm that you need to replace the sliding lever control for the rear fan on the MAIN control unit. In order words, you'll need to replace the main climate control switch assembly to fix the problem. It's a pretty common failure on Villagers, if I remember correctly. Hope this helps.

its not in the headliner. its under the side panel in the rear on drivers side. you half to remove the panel on the inside just above the rear tire. since the moter runs sometime i would replace the blower motor resistor first cause these are known for going bad and its in the same area as the blower motor. this resistor controls the fan speeds and if its gone bad the fan dont run right. plus its alot cheaper than blower motor. once you have replaced the resistor you can turn the fan on and see if its a fixya before putting the panel back in place.
