Asked by Feb 08, 2015 at 05:39 PM about the 2007 Mercury Grand Marquis GS

Question type: Maintenance & Repair

The window rolls down but when it come to rolling up its a no go. I checked by hand and it seems that the wires are both ruining correctly.  the top part of the motor the wire guide appeared  to be out of socket i placed it back in . The bottom felt to be in the correct position. Is it possible for the wire to have come off of the regulator?  Can that be repaired or am i taking a ride on replacement lane

You can try to run a hot wire to the motor and see if it will go both ways. If so, you know it's a bad switch.

Sounds like a bad switch. I had to replace my driver's window switch on my '08 Grand Marquis when I bought it. HTH. -Jim

Good Morning.. I have checked all things suggested within this forum. The motor and switches are working correctly. It is the regulator that went south. Does anyone here know if this can be fixed or is it something that has to be bought? Also when removing the rivets is it advisable to replace them as well or can screws be used in lieu of ? Thank you

Like most regulators made these days, the gear is probably made of junk plastic. I would see if I could score one at your local salvage yard or Ebay. If no luck, you will probably have to order from the dealer. I would use screws. Just make sure you use a lock washer.

Your local auto parts store should have the regulator in stock or close by at their local warehouse. It's a late model so parts are readily available. Drill out the rivets and use screws when installing the new regulator. Put a dab of threadlocker on the screws before you screw them in. This will prevent them from loosening up over time. HTH. -Jim
