Electric window issue - TBird 2002 - still searching

Discussion in '2002 - 2005 Ford Thunderbird' started by carlimann, Apr 5, 2018.

  1. We are still searching for the reason, why the electric windows of my 2002 TBird won‘t go up (I’ve posted here before). Over here in Germany nobody knows this car, and every issue means, you‘re in trouble!
    My car electrician has checked about everything possible and finally got to the control unit under the space for the softtop. This unit seems to be in charge of the window management. He says, that it sends no signal (power) to the switches for the windows. He then connected power cords directly to the switches and the windows went up and down.
    Has anybody got an idea, what we can do next? Thanks!

    Well, it sounds like you found the issue, no? Sounds like the rear electronics module. Is there a part no. on the control unit? There are still some genuine Ford parts available for these cars. I use Ford Parts Giant (www.fordpartsgiant.com) or Tasca Parts (www.tascaparts.com). There are others.

    Gus, That link seems to be for a FEM (front electronic module), but it seems like its the REM.
    Carlimann, This link is for a REM:
    https://www.tascaparts.com/oem-parts/ford-lighting-control-module-1w6z13c788ab See if your module part no. matches the one in the link.
    By the way, The FEMs MUST be programmed by a dealer, using your existing FEM for the software download. I don't think the REM requires this software download, but I could be wrong.

    Did you by chance scroll down the page? All three modules are in that page. The REM is the second one
  6. Hi, I`ve described my problem here about a year ago and still have`nt found a solution. The electric windows of my car won`t go up and down. The motors are ok, so is the switch. There is no signal coming from the FEM. If I give 12 volts directly from the battery to the switch, the windows work as they should. The illumination of the instrument cluster and the shifterknob were also without function. On the page of Midwest Tecmart, a company that repairs moduls, I found exactly my issues: no illumination of the cluster and the shifter plus my window issue= FEM problem. I sent my module to the company, they checked and repaired the module and sent it back to me. They were very helpfull, I must say, but told me, that they found no issue in the FEM concerning the windowsignal. I got it back theses days. The illumination of the cluster is ok now, the illumination of the shifter not, the windows still without function. Has anybody got an idea, what I can do next? Thanks a lot!

  7. Hi.
    Interesting problem. I do not have a wiring diagram, so I cannot be specific, but would it be possible to check continuity of the wire between the FEM and the switch? Perhaps there is a break or intermittent connection in the wire or plugs.

  8. Both windows inoperative or just drivers side?
    Passenger window is controlled by REM rear electronic module.
  9. So did this issue ever get resolved?
  10. Both windows are inoperative. As soon as I connect a 12 Volt cable directly from the battery to the main switch, both windows work.
  11. Got to be that computer located in the boot where the top retracts. Just put in a back up camera and had to use one of the out pits from the unit in order to splice into the back up lights. I'm thinking it controls the logic to the windows as well.
    Hell of a system
  12. Hi, you mean the REM? I don`t exactly understand, what to do with a backup camera (sometimes my english is not good enough) and the back up lights.
