Question about 2007 Hummer H3X

1 Answer

Door open sensor

The driver door is indicating that it is "open" even when it is fully closed, thus dome lights stay on. we pulled the plunger switch and tried twisting the wires together to hopefully make a continuous electrical flow, but it still indicates that the door is open. Assuming the plunger part must not be the issue, what is?

You have it backwards, when the wires are put together like you have done that indicates an open door to the module. When the door is closed it breaks the circuit and when open it makes the circuit. Pull the barrel around the plunger as far out as it goes and then close the door, then the switch is adjusted. Also since all doors have this switch how do you know you have the correct door??

When the engine is running the door open indicator on the dash shows a door open, thus when the engine is off the dome light stays on, what could cause this?


On the doors, and in some vehicles the trunk, there is a pushrod style tab similar to a fridge door. When the door is closed, it pushes the tab in, and shuts off the light. Vice versa when one of the tabs is fully extended the light turns on. Check all your doors for the tabs and see if any of them are broken. If they are, then you can solve this by using something to push into the cavity and shutting off the light. Without replacing the broken parts, you could use a small wooden dowel rod in it's place for a temporary fix.

Alternatively, there should be a toggle switch on the dome light that allows you to choose whether the light is on, comes on when the doors are opened, or remain off. It would be just as simple to switch it to 'off' provided you don't rely on it too heavily.

Everytime i lock my van the locks keep unlocking themselves


My Honda did this when the driver's door wasn't fully closed.
Does the inside light (dome light) turn on and off correctly when you open and close the driver's door?

If not, then the door latch might be loose or the door sensor switch might have failed (so it thinks the door is open even when it's closed securely)

Dome lights wont shut off


sounds like there might be 2 feeds coming to where you disconnected the switch, I would co to the reckers & get another one from a similar car. Most of them complete the circuit when they close the switch/door open when the door closes then switch it left hanging open.

Dome lights won't turn off


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?

1998 Ford Windstar fuse problem - dome light stays on etc


you most likely have a bad door ajar switch- the door panel has to be removed to access it, its on the door latch- you can unplug them this will take care of the batt drain prob.as for the locks it may be a switch problem- most ford vehicles will not let you lock the vehicle from the driver's door when it's open to prevent locking the keys in.

Interior Light sometimes will not shut off in Ford Ranger Pick up


If I am not mistaken, the plunger is located in the door with the latch. Most of the time you can just pull the door panel off and adjust the switch. After opening and closing the door, they get knocked out of adjustment. I sincerely hope that this helped you. Take care and best wishes.
