Hi All
After occasional intermittent failure of the electric windows (never long enough to fault find) - they've finally stopped altogether. Better, in a way I suppose ;-)
However, on investigating, have found my wiring isn't following the '81 wiring diagram and is a real mystery! Have tried to find older and later diagrams - those I find still suggest mine's non-standard?
I'm wondering if anyone has come across this in case it is a factory thing as opposed to a later owner modification?
I've attached an image and diagram.
I seem to have a "mystery" red (gone pink?) pair of wires POSSIBLY looping out from the electric window relay's 12VDC output, going off somewhere into the loom and disappearing behind dash and fresh air blower box - before coming back to the input (top) of the correct window fuse 21!
This pink loop is open circuit, so I'm getting no 12VDC at the fuse input despite 12VDC being delivered by the relay correctly!
The pink wires are "odd" - in one respect they don't look quite as old as all other wiring (40-years old). But that said they are laid inside aged-looking black PVC sleaving along with other standard wires through the rear of the dash and elsewhere in the car. There's also many other runs of the same aged-looking black PVC sleaving carrying most of the rest of the cars wiring and I assume this is all "factory"? So I'm 50/50 on them being an ownerpost factory modification....
- Theory is - I could take the pink loop out of circuit, move the window relays 12VDC output to fuse 21 direct (as the manual suggests) and all should work.
- I will see if i get the confidence to do this as a test....
- But clearly I'm wondering what do I risk taking power away from?
Any confirmation if anyone else has come across this - or not - greatly received.
Best regards
Neil
