I have a 2004 Crown Vic -- with a Light Control Module problem. I have access to a used LCM -- that appears to be the same physical size, plug configuration, etc. However, its Part number is:

5W7T13C788AB

I was told it came out of a 2004 Crown Vic.

When I search that part on the Internet -- it seems to relate to the LCM of a 2005 Crown Vic.

Do you know if the two LCM units are interchangeable -- or not?

Could I do any damage in "trying" the replacement unit in the vehicle?

Thanks for any suggestions and advice you can provide

Don't forget that throughout a particular model year the manufacturer may do upgrades and revisions to any and all parts of a vehicle. Depending on the exact date your 2004 was made, it IS possible for it to have a part that was STANDARD on the 2005 models. I have a 1997 CVPI which has parts associated to the 1998 models. Weird, huh?

All I can suggest is to try the LCM and see if it works. If not, go to ebay and have fun!

It's just a SUPER-DUTY Mustang GT Sedan. 198K miles and still rolling HARD.

1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)
STOCK?? I bet it was modified.

13.26 @ 107.24 MPH 1/4 mi w/ me, tools, & full tank of 93 octane

I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings, Kooks headers, 2 1/4inch exhaust, TCI 2200-2400 rpm Stall converter

Many if not all of the LCM's of that generation had the same/similar problems so getting another used one will just "fix" the problem for a time then it too may fail.
What is the problem you are having?
