Hi guys
Im a bit confused now with my faulty tailgate. It meets all the criteria of a faulty switch (upper tailgate opens from dash lower tailgate opens ok with switch )
After research I went to go change switch & someone had already attempted the repair.
Touched the stripped wires together to check latch unlock functionality without switch - nothing.
Is there a voltage reading I should expect on the two stripped switch cables?
Is there another step before moving onto the lower tailgate solenoid change?
Plus if there is nothing happening at my switch not sure how the lower tailgate solenoid change will alleviate issue upper tailgate switch not functioning?
Hope this explanation of my situation so far with tailgate makes sense and any help of the ideal next step would be greatly appreciated
Thanking in advance
Sean

UPDATE
Measured voltage at the switch cables - 5v
Thought the crimp did not look the best from previous attempted repair so decided to take of crimp , strip back to original copper.
As stripping the cable it just popped off in the tool back to the body. Water ingress in cable id imagine.
Now need to start researching how to strip down the upper tail gate trim to gain access to change the whole harness.
Wish me luck

SORTED UPDATE
Upper tailgate now opening from switch
Using these two videos I was able to change the whole switch/lighting harness
?si=PddisdNVowXcikAE
?si=32wTi_HfPHFq-K3s
Felt it was important to update as through all my trawling of forums and YouTube the tailgate issue was all switch and lower solenoid change information.
Lesson learnt from my experience now is a whole switch/lighting harness change is also a fix.

I've had it twice (on my old D3 and my new D4)and know of 2 others where the wires to the switch itself have corroded where they come out of the main loom where its wrapped in tape.

To change the switch and handle you have to dig out the old one using screw drivers then cut the wires as close to the old switch as you can then connect your new switch using solder or but connectors then while it's out test it.as once you new one goes in you'll need a nother one as digging it out breaks the 2 clips.
Enjoy

This just happened for me. In Australia we don't appear to get that white crap interferring with the switch she was clean as a whistle. Upon investigating the cause was one of the wires had actually corroded completely through in a spot where the wires look to have been rubbing only the shielding was holding it together. I didn't even notice it until I accidently broke the wire and corrosion spewed out i had to take back a good 10mm to get to clean wire. Aidan
