Where is the Front Lighting Control Module located on the 2004 Thunderbird?

Passenger side Low Beam headlight inoperative. Changing bulbs had no effect. Ford dealer says problem is the Front Light Control Module (part # 6w6z13c788aa)

I dont believe that is right! I say it is a wiring problem. The module doesn know right from left on low or high beam. Need to trace the low beam circuit back from the light bulb socket to find the open wire. That's my story.

Honestly PR I have had to change several on Fords because of lighting issues, just a comment.

Me too lots of them but not T-Birds! I still say it's a wiring issue! Low beam on one side only?? Module should be lights on or not.

OK no comment.

Shouldn't be a problem finding a module if that's the case. Just saying.

Currently a Nation wide back order for Ford Dealers and OEMFordPaarts.com. Tried module rebuilder and they say that they can't rebuild the module.

I have ran into that before as well, and had to wait, they have probably checked the circuit to the bulb, if you want to try let us know if we can help.

Maybe that's the reason you cant fnd one is they give a bunch of trouble. I am sticking to the wiring issue though. Let us know when you get it fixed. These modules do give problems but i have never had THAT problem with one! A 'Snap-on modis ultra' scanner sure would be a blessing here! Have you had it tested elsewhere? That part number (6W6Z13C788AA) comes up for the ignition control module. But may be superseded. Be a shame to have to park a car just over a headlight! I would find a way around all of this bs! Hope you get it fixed.

Still chasing down wiring as potential problem. I looked up what I could find in Chilton on-line Manual and found in the Auto Lamps section that the control module applies a ground to pin 1 of the female socket at the lamp for Low Beam and a Ground to pin 3 for high beam. I took the following measurements (pin to chassis ground) at the connector and they have me stumped. Ignition off: Pin 1 15 ohms Pin 3 15 ohms Ignition on: Low Beam pin 1 2 ohms pin 3 13 ohms Ignition on High Beam pin 1 14 ohms pin 3 2 ohms Sure wish I could get a diagram of what's in the control module. Any ideas??

At the bulb connector what is missing, battery voltage or ground, for the low beam circuit with lights on? I don't see how it can be a ground problem since the high beam works. It only has one bulb and one ground per headlamp. If you put battery voltage to that bulb's low beam wire does it come on?

12V power is fed to pin 2 of the connecter (both measured and in the diagram I am using). The diagram (which is becoming suspect) shows ground applied to pin 1 for low beam and 3 for high beam via the control module. I have not tried directly applying ground to pin 1 while maintaining power to pin 2.

PR it's a pwr/switched ground like GM

At this point just want to know IF the bulb will work! If it were mine i would put a universal headlight switch in the dash with a floor dimmer befor spending that much money or parking the car! I wish we could get our hands on some of these vehicles because it's nearly impossible to fix them on the net!! And this person seems to know a bit about cars, so those that don't well.....

Is it the left. Ground the blk/grn wire to the high beam wire. Blk/red to the RH light. Blk/red to low beam LH. Blk/wht to RH

It's the right hand light. Just to be sure are you saying to cross strap Right headlight Pin 3 (BK/RD) to Left Headlight Pin 1 (BK/GN)? Sounds reasonable if the current carrying capability of the control circuit is adequate. Relative to previous comment, if this keeps up, installing a set of old fashioned headlight adapters and new switch may be the last resort vs. parking the car.

RH Low beam blk/wht re read low at the bottom. Sorry was out broken water connector at the well. LH blk/red.
