How to replace 04 ranger mirror switch

How much drain? All vehicles have some drain for the 'keep alive' function. If you are sure that all fuses (cabin And underhood) are ok. One common problem to look at is the plug connection on the firewall. Unplug it and check for water/corrosion on the male and female connectors in the plug. If all ok, time for more comprehensive diag. Instrument displays are controlled through a module. Power windows are completely separate circuit. v This time of year, I would be checking all harnesses for critter damage. Hope this points you in a direction. Have to start with the basics.

Hi Michelle , what make model an year vehicle ? On some vehicles this is function is controlled by a door module .

In order to control outside rearview mirror operations, as well as other door functions, the front door modules must be powered up. For this purpose, battery voltage is supplied from the rear fuse block, through separate circuits, to each front door module. Each front door module is separately grounded through a ground stake. The front door modules also use these power and ground supplies to drive the mirror motors, and to provide power and ground to window and lock switches and door lock actuators. In addition, the driver door module (DDM) uses these power and ground supplies to power the driver door switch assembly (DDSA) and integral mirror control switches.
Could have DTC'S - diagnostic trouble codes stored in BCM - body control module .

If both mirrors in failure mode, then switch fault is a good bet. To check, remove and replace.

Check to see if the mirrors share a fuse with another circuit, if fuse is good, check for 12v at the mirror, if no voltage check for 12v going to the power mirror switch. If no voltage check for 12v at the ignition circuit that feeds 12v to the power mirrors.

It's location is in the fuse/relay box under the hood. It's a 20 amp fuse in position 23.

If the fuse is OK there's a fuel pump shut off switch located under the the glove box just above the carpet. To reset it, turn the ignition switch off, push the button on the switch, then turn the ignition on wait a few seconds then turn the ignition off.

Hope this helps

check wire continuity with multimeter, have had switch go out on ranger as well.

The power windows are controlled by the Generic Electronic Module, also the wipers and interior lights go through this module, the problem is most likely the module itself, the module is behind the radio, but check the fuses , fuse #1 7.5A Power Mirror Switch, fuse #26 10A, power window relay, in the underhood box check the following: Fuse #4 20A** Power Windows

Hi!
