[2000cr-v]

Hello, I have a 2000 CR-V. My interior lights just stopped working. There is no power going to the map lights or the dome light. Also noticed the rear wiper stopped working but the rear wiper washer still works.
I feel like this a some kind of faulty body control module.
All fuses are good.
Any ideas?
Thanks!!

I'd have to check my manual, but I'm pretty sure these two things don't have any shared circuitry. Have you tried changing light bulbs and fuses? Most circuit failures are from one of those. Also, did you just lose the center dome light, or are all 4 interior lights out?

Just checked my manual, but my car is a 98, and my manual covers 97 and 98 CR-Vs only, so I don't know how much help this will be for you.

According to my FSM, there is no shared circuitry between the interior lights and windshield wipers, except for fuse 41, but fuse 41 (100A) powers everything except the starter, so you'd have nothing working if that fuse blew.

The rear wiper is controlled by an integrated control unit, which mounts to the back of the main dashboard fuse block. This could be to blame for the rear wiper, but it also controls the front wiper intermittent mode, so that would probably be broken too if the integrated control unit is broken.

The interior lights are not connected to the integrated control unit, but the circuits for that are simpler.

Never underestimate the possibility of coincidence. Modern cars have so many parts, that they frequently have simultaneous unrelated failures, either because of unusual vibrations, like speed bumps, or sympathetic voltage changes, or something else.

I'm attaching pics of the wiring diagrams from my FSM, in case that helps you.

Here are some pics of the harness routing. This should help you track down wiring problems if that's where your problem is.

I noticed the wires for the rear (cargo area) dome light, and the wires for the rear wiper are in the same part of a couple of harnesses. If one or both of these harnesses, or the connector between them are damaged, it could cause these two systems to cross-circuit, blowing the fuses or frying wires for both.

I know you said you checked the fuses, but I would suggest replacing the fuses for both systems anyway, because sometimes a fuse can look ok, and still be blown.

Good luck! Please post when you get it fixed!
