Heated Mirrors - BMW Forum

Could some one please let me know how i can tell if i have heated mirrors or not? I have a 1995 325is. I'm pretty sure i don't have the heated mirrors because i haven't seen any option in my car about it, but i'm still finding things out about it since i've only had it for a couple of weeks. Anyways, if you don't have heated mirrors (which i don't think i do) is it possible to wire them up to work if i were to get them? (spend the extra $4 at gs4y.com) Could i wire them up to the defroster or to a toggle or how exactly do they work. Thanx in advanced!

BMw seems to be big on pre-wiring stuff, ie alarm and cd changer. I wouldn't be surprised if the heated mirrors were pre-wired as well.

I don't know how to tell if they are heated though.

yeah if you have heated mirrors, they will always be on when the key is turned to the on position, i guess you could just remove the glass and look for the heating element

It's really easy to tell if you have heated mirrors. After the car has been running for awhile touch the mirror with your finger. If it's warm then you have heated mirrors. Kyle is right they are on all the time.
You could also pop the mirror off (it's just snap fit to the housing). Just be careful because the wires to heat the mirror are actually attached to the mirror (on the reverse side). You don't want to rip those off.

So technically, even if it didn't come prewired, you could replace your stock mirrors with electric/heated mirrors and simply wire the heating part to the key so it comes on with the car? Would this work? if so i'm gonna get the heated mirrors, thanx.

I changed my mirror a little while ago (because it was rusted) but here is what I saw.
There are 4 wires going to the mirror motor. BMW spliced into 2 of those wires (can't remember which colour they were). The 2 wires coming off that splice get plugged into 2 small connecting points on the mirror. So, I think you can convert to heated mirrors but you would need the mirror piece with the connecting points and you would need to do some splicing.
That's just from my observations though, I really don't know if it will work.
