2G Power mirror switch wiring harness...

[carvinbassplyr]

Ok, so I know there are plenty of threads on here about power mirrors and the fact that they are basically a prop on DSM's (they never work), but I still refuse to except this. I've read through as many of these threads as I could find and subsequently did the following;
-I checked the stand alone fuse as well as the the fuse shared with the cigarette lighter and both are fine.
-I ordered and installed a new switch and that didn't solve the problem.
-I checked the new and old switches for continuity and found that BOTH were fine
-I checked for voltage at the switch and it is there.
-I ran a jumper ground wire to the switch/harness and still nothing.
-I supplied power to the mirrors independently and they work fine.

My only conclusion is that the harness and subsequent relays have deterioration somewhere that I can't find/see. I know the circuit setup of the switch relies on all wires having the ability to function as positive AND ground wires at any given time. (example: wire X=positive and wire Y=negative the mirror goes up; wire X=negative and wire Y=positive the mirror goes down). So something is hosing up the circuit and not sending/allowing the corresponding polarity when pressing the switch...thus they don't work. I really don't want to do a wiring harness overhaul as the wires for the power mirror switch are spidered into so much other nonsense further down the chain, but I'm honestly baffled as to what else could be causing this problem...Did I miss something? Any help would be SO appreciated!

well I guess im lucky that my mirrors work fine, I encountered a similar problem on my 05 G35 with the power seat switch. I had to replace it due to the previous owner spilling soda on it I assume. but any way, so I finally cam across a used one from a local on the forums so after going through the trouble of switching the plugs because apparently they changed them in 06 ( Thanks Infiniti) I get it all back together and it still doesn't work so I test the motor, it works fine I test the switch and it worked fine, so the only thing I could think of is that the switch wasn't allowing enough current to power the motors so what I did was bridge wires and soder them to the back of the little circuit board and BAM problem solved.

the boards looked perfectly fine to me but somehow they weren't letting enough current pass through them to power the motors. It really racked my brain for about a week while I tried to figure out the problem

so im not sure if this could be your problem but it was mine, and i tested the switch for continuity as well and it checked out perfect just like yours

How would I do this on a power mirror switch, especially with all the polarity switching?

well the switch in the power seat was a revers polarity switch as well.

but you would need to make sure you have enough room to do it without it interfering with anything, then basically i traced the contact points with a wire and sodered it right to the board you just cant touch the main "power in" or it would have constant power. i haven't even see that back of that switch so i dont know what it looks like

can you post a pic of it? and ill see if i can help out

You'd have to really hack up the switch to do that...you'd have to cut hole for the wires to fit through and then the switch would be hard wired and have to be unsoldered every time you need to take the dash apart to replace/repair something. There's gotta be another way.

oh. yeah i have never really checked out that switch in detail so i wasn't sure.

good luck man!

No one else has ever run into this problem or cared to cure the Gremlin in the power mirrors?
