Dome lights/key cylinder light do not work.

[acamato]

I just got a 00 Discovery and the dome lights/ign switch light do not light when the door is opened.

The dome lights do not work when they are manually switched on.

The keyless entry works, the vanity lights do work, sunroofs work.

I checked fuse 20 and it was good.

Where is the C0706 ground? The rave shows it by the pass side taillight. Is it inside the passenger compartment? behind the taillight?

I checked the voltage from the light to ground (front door hinge) and got 8 volts on each side of the light socket.

It is inside of the passenger compartment, behind a little plastic louver, aft of the right rear wheel well.

Thanks. I will check the ground tonight and see if that solves the issue. If not, I am thinking it is a BCM issue.

[lowest bidder]

in my case, that grounding point had never been tightened with a nut, it was held in place on the stud by the force of the wires pushing against the connector.

Does anyone know where header 0289 is? It is after fuse 20 and feeds the ign switch light and header 0723 (which feeds the interior lamps).

I want to make sure this is good.

[acamato]

Well the ground was nice and tight. Time to look at the wiring diagrams to see where I should look next.

I was driving around the other day and the interior lights came one. There must be a loose connection somewhere. I also discovered I also have an issue with the drivers door switch (lights don't come on when the door is open). I will swap out the actuator with my DII that doesn't run.

Without confirming with RAVE, I believe that header is in the front passenger (RH) foot-well. Above the carpet line behind the glove-box. Think there are three shrink wrapped connections. I have had to clean corrosion out of one of them for a dome light issue before.

[acamato]

I think that may be the problem. I found the section of the RAVE shortly after I asked where the header was. I removed the cover/trim in the footwell and found the harness. The bracket, on the firewalll, that holds the cover was rusted. I bet I have corrosion on the harness. I didn't remove the shrink wrap that day because it was cold outside and I wimped out. I did wiggle the harness feeling for the connectors. The lights came on about a day or two after that. If it is warmer this weekend I will take a look at it again, this time I will remove the shrink wrap and clean the connectors.

How should i clean them? brush? contact cleaner? Should I disconnect the battery prior to cleaning them to reduce the risk of a short?

[belew]

I use the CRC brand electronic contact cleaner. Couple of sprays and it looks like new. Usually no brushing or scraping required.

It's always recommended to disconnect battery. Although in practice it's seldom done.

Finally got around to looking at the connectors. This is what I found when I removed the harness cover....





All three had corrosion issues. There were a few jumper pins that were completely eaten away. I am very shocked that I did not have more issues.
