Driver side running board... won't light

The running boards on the passenger side of my 2004 4runner limited will not light. I've replaced both bulbs, but still no luck.

Any clues?

Should they turn on with the driver side boards?

Ditto

I had the same issue with my 04 Limited. One of the lights on the drivers side quit working. I also replaced the bulb (hard to get at with my thick fingers) to no avail. The dealer said that there was an issue with the wiring of the running board and quoted me $500 to replace (!).

Needless to say I have been living without that one light for a couple of years now.

Let us know if you obtain any further information.
 
I think the wiring goes into the two kick panels. I would try to remove the socket assembly from the running board open the kick panel and unplug the wiring to the socket. Use a VOM to determine the problem.
 
yes...check and see if there is power coming to the board. There is a little white connector that I remember unplugging when removing the board. It could have been damaged or something.

Sorry... where exactly is the kick panel?

OK... that would make sense. The bulb sockets for the boards are part of the board assembly... so there must be a main power source for the boards. Is it in the front or back?
 
OK... found the problem. There is a white connector under the vehicle (located around the middle of the running board) that powers it.

The wires coming out from under the vehicle have come loose from it's plug/connector. The running board side is fine. I simply need to get that fixed.

Funny the exact same thing happened to me... Lucky rock hit I guess...
 
have SR5 4WD and want limited running boards

i have a SR5 and would like to install Limited running board lights have any idea where can i get that whole piece on the internet?
 
OK so I am resurrecting this because similar issue... but mine I am sure is electrical...... both lights are out on the drivers side. Bulbs are good. Volt meter is showing a -3.6 on one socket end and a -7.6 on the other socket.

The main plug that goes into the rail reads 12 so I would think there is the 12 volts needed -- I am confused why the voltage is wonky on each end socket?
I dont know much about volt meters, but I think I am using it right.

Passenger side works fine. Anyone have some advice on helping me troubleshoot this?

Usually if you get a negative reading as in -3.6 and -7.6 you have the voltage meter test leads reversed, i.e. red lead to ground and black lead to positive/hot, but I do agree that I think you should be getting 12 volts at the sockets, so if you had the test leads reversed you should be reading -12 volt.
 
Ah, good info. I did check the working passenger side to test my meter skills, and a working bulb socket reads 12 (or -12 depending I guess).

So that means something in the driver bad rail is failed from the main socket to the two bulb sockets... Do I need to remove the rail and start tearing it apart? Could it be the female side of the main recepticle since the male power from the car (to the rail) reads 12.

Could dirty contacts cause this 3.6 at one bulb socket and 7.6 at the other?
If I let the lights go out, it does disappear to zero I think.... so they are getting SOME voltage when they are activated on the bad drivers side, they just dont get to 12 volts.
 
Yes a bad connection at the connector to the running board could defintiely give a low reading at the blub sockets, it very well could have some corrsion where the 2 connectors come together or the metal connectors inside the plastic could be spread open too much and not making a good connection, try pushing/pulling/twisiting on the main connection and see if that gets you a better reading.
