outside rearview mirrors

Unread post by whysaabme » Mon Aug 25, 2014 3:44 pm

I own a 2004 LeSabre that doesn't have heated external mirrors. Besides the mirrors themselves, what else would I need to replace to have heated external mirrors? The car has just under 70K miles, so a little expense would be acceptable. Kevin

well it gets a little complicated. do you have manual AC or do you have automatic AC?

it matters because the heated mirrors work on the defrost circuits

It is a manual heater/AC system.

you probably have most of the wiring in the system but you may have to modify a couple of things. here's a couple of diagrams you can compare

start from the defogger relay and go from there
