Rear tailgate indicator light stays on even though tailgate is closed tight. with this light staying on the doors will not lock. Is there a sensor in the tailgate door that might be obstructed.

Sounds like a bad switch on the tailgate. Open your tailgate and look for a switch. When you find it...press it in completely and see if the sensor light goes off. If so, replace it.

The door lock itself causes the light to stay on. Not cheap to replace.

Even if the tailgate locks properly there may be something blocking the light switch. Happened to me after carting firewood and the trunk had lots of wood chips and sawdust. I cleaned it out with a paint brush and vacuum and the light was fine - but it did take a couple of tries!.

The door sensors will need to be replaced. A screws can be removed and then a wire can be taken of and you then can replace the switch.

Been having a problem with the dome lights on a 99 chevy blazer. Still can't figure out what the problem is. There is a dome light overide button located under the dimmer wheel. When I push the overide button in the dome light goes off, but when I open any of the doors the dome light will not come on. When the overide button is out the dome light stays on all the time and will not turn off even though every door is closed. I checked all the pushbuttons and everything tests good. Has anyone had this problem and know how to fix it?

sound like your fluid sensor may be stuck or bad if light stays on try tapping the washer motor on the resevoir if it goes out faulty sensor as for the door ajar light it might have bad connection with sensor saying the door is closed local dealer should be able to troubleshoot sensor

I just went out and looked at mine and couldn't find the switch either. However I would reccomend going to each door (front back and tailgate and reshutting each one firmly.

This switch is in the lock it self. Push the lock into place with a screw driver (use the screw driver like the bar that the lock comes down onto)and the light should go off it you have all the wires still intacked.

I don't know if this will work, but at least it is worth a try. Spray some WD40 liberally over and into both tailgate latches. Try to get up inside using the straw extension. Open and close multiple times to work it in. I suspect there is an internal latch switch, which controls the display, that might be dirty, corroded, or just not working. Of course other causes are possible. I hope it works.

I had this problem on my 2003 explorer and took WD40 and gave the lock mechanism a good dose where it meets the clasp on the door jam. Then open and close the doors a couple of times to get them working. They get gummed up and sometimes have a tendency to stick.
