Ford door switches—a known problem

Remember the pin/plunger switches that car makers used to install in the door jamb? Well, you won’t find them in Fords—some brilliant engineer had a “better idea.” They decided to place the switches inside the door right under the latch mechanism. When the door latches, a lever deactivates the switch and the body control module turns off the interior lights. Good so far….. The problem is that the switches gum up with grease from the latch mechanism or corrosion. That’s when interior lights stay on.

Some shops have reported success by saturating the latch mechanism with a rust penetrant and opening and closing the door about 20 or 30 times. That works the penetrant into the mechanism and some of it finds its way to the lever and switch. You really don’t have much to lose by trying this method because the only alternative is to remove the door trim panel and replace the switch.

I’ve tried this on a few Ford vehicles and had success. However, it’s not a long term fix. You will have to do it about twice a year.

Erratic transmission fluid level— Taurus, Windstar, Freestar, Sable, Monterey

You may notice an erratic fluid level reading on the dipstick or possible leaks around the filler tube and grommet on the following vehicles: 2000-07 Taurus • 2000-03 Windstar • 2004-07 Freestar • 2000-05 Sable • 2004-07 Monterey.

The affected transmissions are the F50N, AX4N and AX4S. The problem is caused by a restricted transaxle vent. The fix requires replacing the transaxle vent with a 90° vent on the transaxle back to the cowl area next to the brake master cylinder and tie wrapped in place with the end of the hose facing down.

The new vent is Part # 1C3Z-7034-AA. If you need more information on how to make the repair, see Technical Service Bulletin 06-18-13.
