rear lift gate dome light switch

rear lift gate dome light switch

Postby timothy47130 [OP] » October 11th 2015, 7:10pm

Has anyone found a place that sells just the dome light switch that's on the lift gate support strut ? I have disassembled mine and it has one set of brass contacts broken in it . I have also gotten 1 from the salvage yard that has the same problem . and the other 2 I checked at the salvage yard were broken also . Im going to try to take 2 and make one . They have 2 sets of contact sweeps like a fuel pump sender arm in them . Between the 2 I should be able to solder parts in to make one . Oh crap I just gave myself an idea talking about a fuel pump sender . Maybe I can use the brass sweep off my old fuel pump sender to fix it . I guess we will just have to see . 8-)

Or you could replace it with a magnetic type switch.

I have the same issue. Where is the switch and where would you find a magnetic one?

I miss not having the light come on.

Sorry it took so long to post pics. I was off work on vacation for a week. But anyways here is how I used 2 dome light switches and a little soldering to make 1 good one switch. I will try to upload the pics off my phone tonight.

Here is the switch repair tutorial that anyone with just basic soldering skills can do. I suppose if you don't have any soldering skills you could just tightly wrap the wire around were I soldered it on. It wouldn't be any were near as reliable as soldering it on, but I'm sure it would work for a while.

1.jpg
Both switches had one side of the little brass fingers/ contact sweeps corroded off. Every one out of the 5 I pulled at the salvage yard was this way. I suspect this is the constant Hot side of the switch and thats why it corroded off
2.jpg
The o-ring shown is all that hold this assembly into the outer plastic tube. The o-ring is also what hold the contact sweeps in. If you unsnap the little cover were the wires come out of the switch, and spray the inside of the black outer tube with a little wd40. The internal switch assembly shown slides right out with the push of a screwdriver from the wire end of the tube.
3.jpg
Remove the o-ring on the (parts switch) and pull out the little brass contact sweep. Next clean up the contact ends of both contact sweeps that will be on your good switch with a scotch brite pad or fine sand paper. Also clean up the wire end of the contact sweep you going to solder. Then solder your wire back on the salvaged contact sweep, and Reinstall both of them as shown with the o-ring holding them into the good switch. You might have to bend the contact end of them in just a tad to make sure they contact the metal ring thats inside the switch to properly work (sorry no clear pic of the metal ring but you cant miss it)
4.jpg
Push it all back into the outer tube, and snap the cover back on the wire end of the switch. When properly assembled the switch end should stick out as shown. I recommend the next step but its optional. You can hook up your multi-meter and cycle the switch while you test it for continuity ( so you know it works before you reinstall it). Then all thats left is to reinstall the switch on the lift support. And if all went well you can finally see what you are trying to find in the back of your van at night.

It really don't take long to do it either. And while it might seem like a small thing. It is one hell of a help at night. I was playing the run to the front of the van game. Opening a front door to get the dome light to come on. Then running back to the back of the van. And let me tell ya that gets old quick.

I think Lumpy made his own version of that, but every time he ate beans the dome light wouldn't shut off. :confused:

Nice job on the switch repair. When you think about the beating that switch takes from the liftgate, no wonder the ones in the junk yard were all broken.
