Curiosity question.

I have the standard rear view mirror in my 2002 Roadster with the flip lever for day / night use. There is factory electrical wiring feeding into the mirror's mounting bracket which I can only guess is for a defroster's heating element but I cannot find anything about this on the forum, online or in the manual to support this assumption. Hence, my question: What is this wiring for?

Also, the owner's manual states that the outside mirror defrosters will activate with the ignition switch in the #2 (Run) position but there is an asterisk included. I cannot find in the manual what the asterisk implies. Do they come on regardless of the outside temperature? And if the rear view mirror does have a defroster does it come on with the outside mirrors, too?

Thanks guys!

Some mirrors have a infrared unit in the base of the bracket for the alarm/central locking. Code S875 in the build spec.

The * in the hand book means that the feature may not be fitted to all cars. Down load your build spec and you will be able to see if your car has the outside mirror defroster fitted. Its code S314.

Thank you for your input NZ00Z3. I checked my build sheet and I do not have Code 875 listed but I do have Code 304 for Remote Control Central Locking. The back of the mirror and its bracket both have plastic access covers but they are the same black plastic as the mirror housing so I doubt that there is anything infrared-related going on there.

I do have Code 314 listed but it is attributed to Heated Windshield Washers. For grins I touched the surface of the driver's outside mirror when out was out for a drive yesterday and sure enough it was warm to the touch so I guess they do come on with the ignition switch in the #2 position regardless of temperature. The interior rear view mirror was cold.

Thank you for your time, Bud. Much appreciated!

Build Sheet Info

Samuise,

This site was in another forum. I used it and, BINGO!, there was my build sheet!

Just enter the last 7 digits of your VIN and that's all you'll need to do. Here 'tis:

Hope this helps.

Heated mirros

Yeah I have never found out how the heated mirrors work, seems they are on all the time, not just when defrost or seat heaters are on, if someone knows I would appreciate. As far as the rear view mirror goes I yanked out the RF board and wiring and relocated in the dash, allowing for replace of mirror with a much smaller/appropriate size (got from an old MG), a worthwhile upgrade, RF still works fine within 20 feet or so.

About those mirrors....

mcheeb,

The outside mirrors come on when the ignition is turned on regardless of heater settings.

I know what you mean about the rear view mirror, it is big!

I've been wondering about rear-view mirror swap for a long time.
Should probably get the build sheet on my car. Thanks for the link on that.
