Wiring up the heater elements on the electric door mirrors.
I'm trying to replace my door mirror glass on an MX5 2002 model with the heated door mirror type. I have removed the door panels and checked the wiring to the the door mirrors motor and there are two extra wires leading from the car to a plug connector inside he door panel. There is no live feed. I have checked all the fuses, including the fuses under the bonnet. The car manual refers to operating the door mirror defroster by switching on the rear window defroster. Can you advise if these extra two wires are for the heater elements on the door mirrors, and how do get a live feed.

Hi, I have a Mazda 6 Estate - I've just had the glass out of my mirror this evening, because my mirror heater is not working - there was a bunch of wires into the mirror unit - two of which went to spade connections on the back of the mirror. The glass itself is on a plastic mount. The mount and the glass should just lever/pull out - that's what I did with mine - I was worried it was going to break though, it took substantial force! Once out I could see a plastic rectangle with rounded corners that it had been clipped onto. It clipped back into place with out any difficulty (on mine there is a wire guide behind the glass - just make sure that you haven't bent it upon removal - I had, but the pliers straightened it again).

Hi. If it is a late model VW then you need to pul the mirror out. It is held in by clips, use a large flat plastic lever to pull out. Be careful as they break easily. Test the leads of the heater element with a bulb type test light. If it lights then replace the mirror glass, if not then it is more likely the switch. If only one works, then check the wiring harness at the rubber boot between the door and A pillar for broken wires. Also check that the outside temp sender is working, as in warmer climates the heater circuit switches off above 9 degree Celcius. Kind regards, Neil
There should be a plug for the heater element. I think a new replacement comes with it, I am unsure. But just remove the old glass by using a screwdriver, wrapped in tape if you want, to pry it from the clips. The clips will release it, then unplug the heater element wire that is in the mirror. Plug the new mirror heater element, install mirror, it snaps into place, just give it a little pressure to make sure it is seated in the clips correctly.
Before servicing the vehicle, refer to the Precautions Section.

first obtain a replacement .the cover with tape to prevent shattering the glass then carefully prise of the glass with a screwdriver refitting should be just a case of cleaning any glass away and removing adhesive tape and refitting the glass the heating element is part of the housing and the heat should just transfer through the glass ..not a hard job ..just tricky and time consuming ..if the housing has been damaged .then its a bit more difficult ..first obtain a replacement and then remove the door card then the fixings should be visible remove them and the mirror housing should come loose remove any wiring from the loom then fix the new unit connect any wiring then refit the fixing screws and then replace the door card ..again not the most technical but of work but time taken will show in the end result ..dont loose you temper as it is a bit fiddly ..if in doubt get halford to do it for you or any other similar garage

REMOVAL AND INSTALLATION
Exterior Mirror Glass, 2001 model
Removal NOTE: Exterior mirror glass is serviceable only on vehicles built after July of 2001. NOTE: Passenger side exterior mirror shown, driver side exterior mirror similar. All mirrors
Position the glass in the full up position.
Locate the notch at the bottom of the exterior mirror glass.
Release the exterior mirror glass.
Insert a long flat-bladed screwdriver in the notch.
Push the screwdriver into the notch until the glass is released.
Position aside the exterior mirror glass.
Disconnect the electrical connectors.
Remove the exterior mirror glass (17K707) passenger side or (17T675) driver side.
Installation Heated mirrors
Connect the electrical connectors.
Position the exterior mirror glass on the exterior mirror motor.
Place a hand against the back of the exterior mirror housing and a hand flat against the exterior mirror glass. Press the glass in place until fully seated.
If only the glass is affected, it can be replaced by slipping a new mirror element into place and locking it. Some mirrors press in, others are locked with a screwdriver turning a little gear through a slot under the mirror.
If the mirror plastic body is broken, you can also replace that with a used assembly from Ebay or a junkyard. Replacement requires removal of the door panel, which is more difficult than replacing the mirror. Be sure you have re-connected all the wiring harnesses and checked the mirror operation if it is electrically adjusted before replacing the door panel. Replacement assemblies range from $20-$70 on Ebay. Glass only is much less.
