Hi again, You gave me some great advice on my suspension rattle so I'm back with another question. I posted this at Green Hybrid also, with no luck so far.

2007 Escape Hybrid, problem is that the interior lights all stay on until the battery saver kicks them off after 30 minutes. I read that the door switches can stick, so I sprayed the latches with WD40, although I'm not getting a door ajar signal, so I'm thinking it may be a stuck relay somewhere.

Any idea where the interior light relay is located?

Thank you in advance.

Tom

Several Fords I or my company owned had this solution. The F series used some sort of electronic switch on the door lock and striker. When I sprayed electronic parts cleaner on them the lights would go back to normal operation. Some vehicles used a ground on the door switch located on the A piller. Problem went away when the rust was removed.

The 2007 Escape (in fact, every E/M/T) has no relay for the interior lamps. They're controlled by solid-state FETs in the Smart Junction Box, along with most of the other lamps.

Have you looked at the switch positions on the lamps? There's an always-on switch position on both the middle lamp and the cargo lamp.

Thanks for the reply. Yes, I have fiddled with the switch on the light. The overhead light module has a right and left reading lamp and a bar lamp for the rear position. Moving the switch allows me to turn off the bar light, but the reading lamps remain on.

It is under warranty, so I can just ask them to fix it, but I'm worried that they'll mess something up in the diagnosis process.

Here's the wiring diagram for your 2007's interior lamps (the wiring is similar for models without the moonroof):



There is one thing you can check: connector C931, the connector to the main front dome lamp with the map lights. Close the doors, wait for about a minute, then remove the dome lamp and use a high-impedance multimeter to check for continuity between the BLACK wire and the PINK wire in that connector. If there's 0-ohm continuity, that's the reason the lamps are on, and there's a short somewhere between the PINK interior-lamp feed and the ground (or the BLACK wire in that harness). A wire is probably pinched somewhere, or maybe a part of the lamp assembly is touching metal.

You can also check connector C926A, the connector to the cargo area lamp.

Finally, check the center dome lamp and connector C918. This lamp uses the housing to provide the ground for the ON position, so one of the wires may be pinched.

HTH!
