1997 Cougar warning light

My 1997 Cougar (just purchased) has the "open door" warning light illuminated in the instument cluster all the time. Both doors, trunk lid and sunroof are closed but the light stays on. I checked the door jam light switches and they function normally. Any ideas? Am I missing something here?

Thanks,

Tony

Spray the switches good with WD40 and work them free. They probably stick a bit internally and that's what triggers the light. Fords are bad for this.

OK????

The switches work fine as the interior courtesy lights are going off when the doors are shut. Are there more "contacts" besides the courstesy lights on these switches I don't see? I'm not happy with WD-40 for electrical stuff as it it petroleum based instead of a solvent that has low to no hydrocarbons.

Any help in this area is greatly appreciated!

WD40 is fine for this purpose here. I use it all the time. It's a slightly better penetrant than a lubricant. Not bad overall.

Again, those switches are known for failure and sometimes cleaning doesn't restore proper operation.

Didn't work!

BUT! The Mercury dealer said the real open door warning light is controlled by a switch located next to each door lock tumbler mechanism inside the door itself. I have ordered one switch and will attempt te change on the driver's side first.

The advise you received about cleaning them is correct.

I have a Mark VIII Lincoln that had the same problem. Found out it was the pass door sw, its located inside the door attached to the latch mechanism. It is a real PIA to change , you have to work by feel. I believe the sw is only for door ajar.

When I bought the part my friends at the L&M dealer said to just clean it with the WD-40, spray the latch mechanism with the door open, drown it and open and close the door.

I did a Taurus and went door by door till I got the light to go out, of course it was the last door.

Right cure, wrong switch. Toyotaman had it right. The switch your looking for is in the door latch. The one your spraying only controls the lights.

Thanks!

I assume you are sprying the latch mechanism without removing the door panel? I'm still not clear as to where to spray the WD-40. I guess I'll jut spray it in all places I can get the small plastic straw to reach.

Thanks,

Tony

The door latch assy has sort a slot were the striker meshes into. You need to spray towards the bottom back corner ( back-meaning the part of the slot closest to the outer door skin)

Many thanks!

I gave it a bath in WD-40 and it worked.

Many thanks!

Your Welcome


It sure beats changing the switch. It's faster and dosen't cost any $
