lost interior lights and rain sensor
Hi Defender lovers,
my L633 has encountered some trouble
.
I have lost the dome lights and these vanity lights (in both sun visors).
Additionally, it looks like the rain sensor got down as well
I've run scanning, and there are 2 codes:
Could the rain sensor code be triggered by a loss of power in the dome lights?
Is there any fuse to be checked or any other simple procedure / solution to fix it?

I've run scanning, and there are 2 codes:
- B10AD-87 Rain sensor; Permanent
- B1D14-11 Interior lamps 2 circuit; Permanent

Hmm. Great start pulling those codes. Sounds like a wire has contacted ground and is shorting out those items -- when the dealer dropped my headliner for an unrelated repair, when they screwed back in the sunvisors they brilliantly screwed right into a wiring harness causing a similar issue. (but I didnt notice the rain sensor being affected, just all my interior lights were “shorted” out). Has any dealer or mechanic been in your headliner recently?
