Option Code For Tow Mirrors

[fajitas21]

I see people referencing Option codes A31 and whatnot to find out which mirrors they have.

 

Here's a link to the mentioned mirrors.

Where do I find those codes?

 

I know my truck doesn't have mirror turn signals, I'm not sure if they are heated, they do NOT auto dim, but they are power, and MAYBE heat, but there is no button for them (perhaps they turn on when I turn of defogger).

DPN is the RPO code. But that is not helpful for replacing yours.

 

I'd just get some aftermarket clones. Plenty on Ebay. Do you want signals or not? Do you you want heat? Both for $250. Power and heat, no signal, for $173

 

Heat should be prewired from the factory to work with your rear defroster. Signal, probably prewired as well.

 

Thread of interest.
