The front wash does work just not the wipers. Anyone know if controlled by a bcu. Motor works if you put live to it but no permanent live feed, this is according to garage. He insists motor is ok when a live feed added. £181.98 for a new one from landrover which i dont mind if i need it.

Diagnostic is needed.

Swapping things randomly can be an expensive way to fix things

And not practical on a computer controlled vehicle like the FL2

Of course some items have to be programmed in before they will work

Yes the wipers are under CJB (BCU) control.
However I'd be checking the electrical connections under the CJB, which can get disturbed by passenger's feet.

I have plugged in my delphi diagnostic and shows 2 faults i cant clear, B10A2 Crash signal and 92ca unkown.
I have also used it to tell me what the wiper position switches are doing when using wiper stalk. All positions show switch off and as i go through wiper switch positions it say switch on. There is no movement of wipers yet the mechanic told me the wiper motor works if he adds live feed.

The only diagnostic that I know to clear the dreaded CRASH status is JLR SDD, which takes about 5 minutes to run the clear routine.

If the Delphi is showing the wiper switch is working, then the issue is between the CJB software and wiper motor, so either an output FET (unlikely), or a wiring issue.
Presumably you've checked the wiper fuse (F22) and relay (R11) in the engine bay fuse box.

Thanks for your help and advice. Just bought this Jaguar Land Rover JLR SDD 160.04 Diagnostics Dedicated Laptop Mangoose PRO | eBay. Had nanocom and hawkeye plus for my disco, sold so i spent on JLR SDD.
