Thread: Range Rover L322 Electrical Fault

Anthony did you check the wiper relay ? The BCU will cut power to your wipers if the blades become stuck, a relay fault might be tripping the BCU ?

Laurie

Have you had the car scanned for faults?

Thankyou Laurie, I will check with the mechanic

Anthony - I had a similar problem with my 2003 L322 after I replaced the battery. Turns out the bcm had defaulted back to delivery or transport mode which (for some unknown reason) prevents the rear wiper and tailgate from working, as well as the front interior light and a couple of other things I don’t recall.
It was an easy fix with the GAP diagnostic tool if you have one? I’m sure your local dealer could also do it (for a price), but don’t let them tell you you need a new bcm.
Might be worth looking into.
