2012 expey INTERIOR COURTESY MAP LIGHT

[Maleficent]

need help with a light issue. I changed out my bulbs to LED. my passenger side, 2nd row light does not work at all. any suggestions?

Welcome to the forum. Turn your bulb around they are polarity sensitive.

 

[Hayes Riviere]

Where'd you get the LEDs? Are they generic or made specifically for the Expedition? Thinking of doing an interior LED conversion in mine.

 

[Adieu]

Amazon $12 will do the trick

thanks Andy, but I am aware of the polarity of the bulbs. I am leaning towards it being an issue with the contacts on the assemply

Hayes, I got the LED set from Ebay, let me know if you need the info. The company I deal with is super professional.

Did the incandescent bulb work? Or is this something that occurred after the switch?

 

[Maleficent]

Andy,

yes, the incandescent bulbs worked before the change
the LED bulb works in the other locations, so I know it's not the bulb.
I also tested the wires/connectors
the issue began after the switch.
all other lights work, For this reason I am guessing it's the assembly and the contacts.

thanks for continuing to walk me through

Pull the whole housing out of the headliner and check the wires on the back side to make sure the plug is still connected. In addition use a volt meter to check the voltage at the connections in the socket and on the back side.

You should have a constant 12V source when the key is ON as well as a switched 12V source, such as when a door is opened or key switched to OFF. And a ground.

Swapping the known-working 2nd row drivers side with the now-dead 2nd row passenger side will tell you if the trouble is inside the assembly or not. Proceed from there.

Andy,

it's the housing for sure. the wires/connections are registering as hot, so I am going to toy with the connector in the housing. I have a feeling that the bulb is not connecting flush with the housing. i'll work on it this weekend and share my results (or failures).

 

[Maleficent]

Flexpedition,

great Idea! I didn't think they were interchangeable due to left/right angles of the headliner.
I'll give it a shot.

thanks again.

Once you have it disconnected, look down in the socket area and make sure that the contacts are in the right place and not bent. It is possible when you installed the LED you bent one of the terminals.

The left and right are interchangeable If I remember correctly. They are just stamped aluminum or tin.

Andy,

sorry for the long delay, life crept up on me. The light issue has been resolved, it was the push button switch that was faulty.
ordered a new switch for $1.25, and presto.
Thanks for all of your advice.
