Recently I took a power mirror setup from a 96 silverado donor truck my cousin was sending to the scrapyard and put in my 93 silverado. There was some splicing involved ; but all I did was basicaly relocate the switch and make extensions. Anyway; the original mirror switch all functions work.. but the L/R dial was broken. So i ordered a new one. Well; 4 now.. part number 15009690. I have tried anywhere from the 20$ ebay specials to the 60$ oem switch.

The problem lies when i press the right ; the mirror moves left.. and pressing left moves mirror right. This occurs on driver and passenger side.


Up and down work just fine, and left selection controls driver and right controls passenger. But left/right mirror control is backward. No wiring is backward that i can tell. What is yalls thoughts???

Why not reverse the wiring since you already spliced?

Cant reverse. Throws everything out the loop. Nothing works right then.

Apparently this is a known problem after reading up on it... since it shares a neutral ; not all switches are the same. Only real way to get around it is to go in the mirror and swap direction in those wires.

I have the same parts and was planning on the same install. Do you know what wiring needs to be changed in the mirror or have a link to the information that explains it?

The lense pops right out & the wire harness is there. Havebt done it yet; but find which wire becomes hot behind the mirror for each then swap them where they hook up At. According to a video i saw on youtube i now cant find

My aftermarket set of powered tow mirrors does the exact same thing. Both my '99 & the '95.
I tried swapping the wires around at the plug when installing them (didnt pull the glass out) ... but never got it right. Multiple combinations and it wouldn't fix it... Very frustrating, so I just left it. Not a huge issue, just frustrating that I couldn't figure it out at the plug.

There is a lot of expertise on this site. Hopefully someone with the answer catches this thread.

Just to update this thread. I still haven’t fooled with the backward internal wiring. But now another question. Don’t these come with a light inside of the plug? (Pin G Brown wire); I tied that one to a hot and no light anywhere... do only certain plugs have the light?

There is an internal light. Aftermarket tow mirrors have the same issue on the left vs right. I ended up adding a secondary ground in my tow mirror. Nick the hick on this forum had some good info.
