Question about 2006 Honda CR-V LX
Dome lights do not come on when doors are opened, but you can manually turn lights on.
All doors there are drivers, and then OTHERS, (wiring)
its wired OR logic, so any switch grounds, it turns them on.
and is programmable on all cars. to have this on or off (features explained in the operators guide, lost that?)
CRV has 3 lamps
all of them are messed up? for all doors.
if yes, ITS programming. is wrong.
the rear light is directly controlled lamp to rear lamp. (hatch glass or gate switches.
and has a slide switch, off,on, auto.
the spots lamps are direct. on, or off
the front however is totally different and wired unique.
as you know the drivers door is unique, as it operates the
keys left in igntion, or head lights left on, mode. so if those work
right then the drivers door switch, is,, working......
the front dome
has 3 modes. again , off , on and auto .
Auto is the MCU , unit, the MCU sees any door open and the front dome gets input to the AUTO pin, and if in auto the lamp glows.
i dont think the MCU is programmable but do read the oper guide for that., i dont have one.

Filament gets fractured, possibly by vibration of the roof lining. I have replaced mine 4 times and while the bulb looks OK it is high resistance, buy a few bulbs and replace them when it occurs.

you have a bad door switch usually located in the door jam if you are sitting in the seat and your door is open look for something that looks like a small button about the size of a pencil eraser it is possible the plunger is broken off so all you may see is a metal object with a hole, replace this if plunger is broken

This sort of problem is most common in vehicles that have been in recent accident.Whats happening is the ground portion of the circuit has poor connection at one of the ground wire clusters.(honda groups several ground wires from seperate circuits into one connector that in turn bolts to the body.)what happens is where that common connector attaches to frame of car gets crushed in collision and or is left loose.One or more of these electrical circuits then continuously searches for its next route to complete a power loop,which is through the first ground in cluster that makes a strong connection to frame. this causes circuits to cross with each other.As in whats happening with your wipers and courtesy light circuits.unfortunately at the moment i dont have electrical schematic in ft of me for your car to be able to tell you exactly where that ground cluster would be located at.Most likely it will be located in the area behind headlights, behind inner fender liners, or along strut towers front or rear.But can promise that this is the culprit behind your problem.Good Luck,Joel

assuming that the light actually works, the problem is probably in the door jamb switch. does the door chime work? if not, there's your problem

Tips for a great answer:
The liftgate lamps
You can't turn them on manually ?
This could be a BCM problem , this best left to a ASE certified repair shop or the dealer .

The liftgate lamps
The courtesy lamp supply voltage circuit of the body control module (BCM) supplies battery positive voltage to the dome lamp, the liftgate lamps, and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps with the switch in the AUTO position. The interior lamps receive a ground at G401 with the switch in the ON position.
Important: If the liftgate is opened after all the modules go to sleep, the dome light will not come on. The liftgate ajar switch input to the BCM will not wake up the BCM once it has gone to sleep, so the dome light will not come on. Once the BCM gets an input to wake it up, from remote keyless entry (RKE) or a door handle, the dome light will turn on when the liftgate is opened.
If the driver inadvertently leaves any interior lamp ON, the BCM will turn it OFF after a 20 minute time-out.
The courtesy lamps will turn OFF immediately if the ignition switch is turned to the ON position or approximately 20 seconds after all doors are closed.
The courtesy lamps are controlled by the body control module (BCM). Inputs from the dome lamp switch and the door ajar switches are monitored by the BCM. When a door ajar switch is closed, or the dome lamp switch is turned to the ON position, the BCM supplies the B+ for the courtesy lamps.
With out a factory Tech2 scan tool or equivalent an knowing how these systems work ,you best bet is to take your vehicle to the dealer or some other ASE certified repair shop !
