GTT mirror demister diagram.. fivebob?

[cedwards]

Mirror demister's keep blowing their fuse in 98 GTT, It doesn't happen instantly but within a week she'll stop working.

Wondering if any awesome peron has a wiring diagram for me to browse..

And if possible a even more awesome person could suggest any potential weakpoints I could investigate.

Thankyou

Wiring diagram won't be of much use to you and there's no diagnostic info in the workshop manual that I can find.

Wiring consists of Battery->Fuse->Relay->Mirror Heaters->Earth. The only thing I can suggest is measuring the resistance of the heater elements, wires should be Red-Black (power in) & White Black(earth)

Oooh Fivebob,

Would you have any info on the 110v outlet circuit? Mine's gone dead for some reason and the rear 12v doesn't work either. Fuses are ok thou...

No info in the manual other than a wiring diagram which shows fuse->relay->inverter/Rear socket.

Maybe a problem with the relay?

I'm assuming the switch under the dash in on?

Haha yep

Many thanks fivebob.

Looks like i'll have to have a play,
The only problem with measuring the resistances is that the short is intermittent, which makes me think it may be more a exposed wire that is grounding over bumps etc,

One other question, it doesn't give the location of the relay by any chance does it??
Thanks again always appreciated!
