Replacing the door ajar switch on my 1998 Lincoln Mark VIII

one thing you can try is to take out the fuse for the door ajar button . this will take it off for sure. you can even try putting it back to see if it may reset

SAFETY FIRST! FIX DOOR!

I suggest check in the Passenger Compartment position 34 with 15AMP for Heated Seats, Backup Lamps, Speed Control, Daytime Running Lamps, A/C Cycling Switch, Digital Transmission Range Sensor, Intake Manifold Runner Control Module.

Hope helps.

the suspension compressor is located on the front corner, passenger side, under the air filter housing. It can be serviced and removed by taking off the passenger wheel and fender liner to get to it.

one of the door pins that sense when the door is open is probably bad, or maybe sticking

Fuse #14 (light green) 30A Cigar Lighter, Cellular Phone, Power Point located in the passenger compartment fuse box.

Spray WD-40 on the door latches, (do that on both sides.) Sometimes they get really dirty and don't make a connection with the door ajar switch. This should work.

Intermittent door switch. See the door ajar solution.

Pls Check Driver's Door Switch Panel for window lock Switch. First of all you better close your window by removeing door uphosting....

You will first need to remove the plastic piece behind the inner door handle that you use to pull the door shut with and there should be a 10mm bolt inside there behind the insulation. The plastic cover behind the inner door lever handle will need to come out. It's only in with clips. Remove the reflective lens on the end of the panel and you will see a phillips head screw inside. It's a long screw so be ready for many turns to get it out. Next, your power window controls will need to come out and they are only snapped into place but be careful with them because plastic prongs can be broken off if not pried out in the right direction. The same goes for the door lock switch. Unplug both once out. You will also see a triangle plastic piece (can break easily) towards the front top side of the panel. Make sure it clears it's way out when removing the panel. The rest of the panel is held up with downward facing plastic clips. Sounds hard but really it's all pretty simple. Study the back of the panel before putting it back on and take your time.
