I'm not sure what is bad in the driver,s sidedoor. The manual door lock switch doesn't work sometimes (Open the door all the way it does work & when cool), the door ajar light stays on,& the light under the side rearview mirror is dim. I just need to to know what to order so I can replace it. everything else works the dock locks & unlocks with the pass switch and keyless entery button.

First, spray WD40 on the door latch and open and close the door a few times. That will probably take care of the dome light. As for the the door lock switch, try swirching with the passengers side and see if it works. That would tell you the switch is bad. If it doesn't, and as you said the door opened all the way makes it work, theat would indicate a problem with the wires in the hinge area. Flexing them by opening the door makes them reconnect.

I'm more inclined to think it's a wire problem more then anything else. Is there somekind of relay that they all go through. that may be bad? As I open the door the lock works and the light under the side mirror brightens up. All these problems happened within a day so I'm thinking they are more likely linked then seperate issues

The wires run through the hinge area and after flexing they can break. That's where I'd start looking.

Hear another thing it does with the key in the run position the driver's side door look works. the door ajar is intermentent. With the key off and the doors closed the truck makes that dinging noise when the keys are left in the ignition. Could it be the electronic part of the ignition switch?

**Bert** · 06-01-2010, 17:23

No, the dinging is because it thinks the door is open. The problem has to be in that hinge area.

I still working on this but if you turn the interior lights off by the switch everything works great. Another thing I found with the cold weather the rear defroster turns on the interior lights & door ajar on the dash which is making me think I should be looking for a short instead of a broken wire. Turn off the lights also fixes this problem as well.

I had a similar problem with the puddle lamps/interior light staying on (and consequently flattening the battery after a very short time), and used a quick squirt of DWF/WD40 on all the door locks. Worked a treat, but yours certainly sounds like a short somewhere.

Just curious if you did try DW40 or the like to see if that might help with that immediate problem.

sometimes I can grab the harness in the hing area and get it to work

**Bert** · 12-01-2010, 16:08

Sounds like a broken wire in that area.
