2nd Gen Non-Engine/Transmission heated mirror

[Tractorat]

The heated side view mirrors in my 02 seem to not be working. The lamp comes on on the dash, but the mirrors dont clear off. It's not jumping out at me in the owners manual where to find the fuse. Anybody point me in the right direction where to look ?

Thanks

T-Rat,

The circuit goes from Battery thru position 2(run) of the ignition switch, then thru Fuse 2 in the Junction Block to Joint Connector #8 where power is distributed to the Heated Mirror Switch, Blower Motor Relay (in PDC), AC Heater Temperature Select, and Blend Door Actuator. Fuse should be good if any of the other circuits are functioning. Inside the Heated Mirror Switch is a Controller Circuit and a Heated Mirror Relay. Do you hear the relay activate and de-activate when pushing the Heated Mirror button? I would venture a guess the relay has ceased to function as designed.

I do hear the relay both on and off. But I guess that doesnt mean the relay is good. Ill take a look at that, thanks.

How do you get to the relay ? Does facia just pry off there ? Or is it a unit that comes out ?

Good questions. I have not had the necessity to pull a heater control panel apart. Anyone out there have some input?

You have to pull the dash basil off first then the mirror/heater/AC module is screwed in place with a lot vacuum tubes and wires on the back side. It is not a serviceable unit. However I was able to clean my switch. Mine was different, as my light was not coming on.

They are not fast, and take quite a few miles to heat up.

Let me study the manual!

OK, first test is to turn on key and then push the mirror heat button while watching the volt meter. You should see a drop in voltage. IN three to four minutes you should feel a temp difference on the mirror surface!

If these test fail then you have a faulty:

* Heated mirror switch, electronic control logic and timer circuity and headed mirror relay.
* Heated mirror wire harness circuits or connectors.
* Outside mirror heating grid (both mirror grids would have to fail)

They should run for 15 minutes! If you push the switch again they run only 5 minutes. To get a 15 minute cycle again the key has to go off and back on.

My guess is you did not leave them on long enough, a wiring issue, or both have failed.

It was on for as long as it normally is when it works.

Deleted for incorrect info.

Did you get your heated mirrors fixed? SNOKING

 

[Tractorat]

Nope, not yet. Got distracted. I thought it could be the relay (I can hear it click). But none of the dealerships I went to showed a relay for the heated mirror.

Relay is part of the pricy module.

Thanks, I figured as such. May just let it go. Dont use it too much anyway.
If I can still get a new one, I might though.
