This is indeed a bad mirror switch, both mirror doing it is the dead giveaway. Replace the switch and all will be well.

My power mirrors on my 2012 Chevy Malibu and I found the fuse for it which was blown. I replaced it and went to use the mirrors again and the fuse blew again. What is the problem?


You have a short in the wiring of that fused circuit, or less likely that one of the mirror motors has a short. A short is an unintended path to ground, like an exposed wire touching body metal, or an internal motor failure. If that fuse is only for the mirrors and nothing else, it will be easier to find. A likely place will be in the door openings where the wires can get stretched and chafed. Pull the protective boot away from the wires where they enter the door, and check carefully. You may need to get to the mirror motors and to the switch for them. If everything looks okay, better get a multi-meter to check sections of the wires for continuity. A wiring diagram will be needed to find the right color wires that you will be looking for. I am guessing that each motor will have 4 wires to it, 2 for side to side, and 2 for up and down. These 4 wires will come from the switch on the driver's door that operates them. Power travels from the fuse to the switch, and then to the mirrors, as the switch operates them. The ground wire for the mirrors will originate at the switch, or it may be a shared common ground at the driver's master switch for the mirrors and the power windows. The short may be in any of these wires, or in the switch (evident at the connector to the switch as melted plastic, perhaps), or a short in one of the mirror motors. Good luck and good hunting.

Power Mirror Wiring Schematic 92 Buick Lesabre 1992 thru 1997 & More


Here is a schematic which my dad & I devised over the course of two hours for the power mirror wiring on our 1992 lesabre, as we couldn't find any wiring info to handle this issue.

http://www.iqmetals.com/else/lesabre/

That's our/my website, and that folder will let you see & get all of the pictures & diagrams

The wiring harness for the power mirror switch was acquired through Rock Auto, and the wire lettering scheme was embossed onto the plastic.
Here's a written breakout of the wires & their locations/purposes.

A= Ground
B= Common Left/Right Motion(Splits to both sides)
C= Common Up/Down Motion(Splits to both sides)
D= Left Side - Left/Right Motion
E= Left Side - Up/Down Motion
F= Right Side - Up/Down Motion
G= Right Side - Left/Right Motion
H= Positive 12V

Now Assuming that all of the power mirrors are wired & color coordinated the same, that would connect....
B -- Light Blue wire of Both Mirrors
C -- Green wire of Both Mirrors
D -- Gray wire of Drivers Side Mirror
E -- Dark Blue wire of Drivers Side Mirror
F -- Dark Blue wire of Passengers Side Mirror
G -- Gray wire of Passengers Side Mirror

In our circumstance we hooked up the power and ground inline with the power window Power(Pink) & Ground(Black) wires which are nearby in the door. The fuse/circuit should easily handle the minor load of power mirrors, even if you were using the windows and mirrors at the very same time... a rarity I do suppose.

Dodge 3500 Diesel power mirrors work side to side but not up or down


Check for voltage on the vertical power output at the switch when operated. If no voltage, try lubricating the switch contacts. Still no voltage? Replace the switch.
If there is voltage, open the mirror assembly and check for voltage there. Is there voltage? Do you hear the motor sound when you operate the switch? If you hear a motor sound but the mirror does not move, it is a mechanical problem which can be easily fixed. If there is no motor sound despite the presence of voltage, the vertical axis motor has burned out or seized. Try lubricating the mechanism and, if still a no-go, replace the motor or the entire mirror assembly.

Mirrors aren't working


Could be a bad connection or switch could need replaced or motor that moves mirror needs replaced...I would start by having power going into mirror checked that is not working to make sure it is getting power and if so this would indicate that it is in mirror motor....hope this helps and good luck and please rate my post if you find this info helps..

Power mirrors not working, have tried moving them manually (2001 Ford Crown Victoria). Both sides only goes down, not up.


If the mirrors only move down and not up I would suspect the mirror switch , the mirrors use one motor to move the glass up and down,and another motor to move them in or out , and if the mirrors move down the motors are working.the only other possible problem would be a wiring but highly unlikely due to the fact that the turning the motors in a different direction is done by switching the polarity to the motor which requires both wires to be good to make the motors move in the down direction ..check the mirror switch I am sure you"ll find that"s your problem

Side mirrors don't work


Usually there is a switch issue. The switch that allows you to select right, left or nuetral can go bad or get dirty and not allow power distribution. If you feel comfortable doing so, remove the trim and gain access to the switch. Using a test light or the schematics, find out which wire is the voltage supply and ensure it has power with the key in the on position but the motor need not be running. If no, suspect a fuse issue, if yes then suspect a switch issue. You can use a jumper wire to apply power to the mirror feeds (again a schematic would be greatly reccomended) and if the mirrors move, viola! I hope this helps

Mirrors will not fold in.


It is a stuck motor. Water gives rust inside housing. Remove mirror and clean motor and components. This is a well known error for H2 mirrors.

Power seat and side mirrors not working


hey
it could be a bad switch if they both malfuntion the same way the only thing they have in common is the switch so most likely the switch.bad plug can also cause this.
