I have done some searches but no joy.
My friend has a 97 300tdi pick up. It has a heated windscreen switch to the right of the steering wheel, which when switched on lights the heated screen symbol on the dash panel. The vehicle obviously doesn't have any heated screens currently and he therefore plans to use this switch to control the front heated windscreen rather than purchase a rather expensive loom.
We guess that the switch and wiring was fitting when the vehicle was built but we don’t know how much of the loom is there, if it includes a timer, if there is already a space in the fuse box the switch runs to and so on.
Is there anyone that has retrofitted a front heated windscreen and use this existing wiring as he wants to or can provide any info on the wiring that we should expect to find?
