Recently I got the bass and treble 59/09 pickups to upgrade my SE Custom 22 Semi-Hollow. After following many wiring diagrams and double-checking everything was soldered properly, everything worked fine. A couple of minutes after the upgrade while playing the guitar, the neck pickup stopped working. After moving the wires around thinking it maybe had something to do with the wires themselves, I found out that by touching the spot where the pickup's wire was soldered with a pick, the pickup suddenly came back to life, but when switched to bridge and back, it didn't work again. I have tried searching online and doing all sorts of things but still no luck. I can provide pictures of my wiring and a video demonstrating the issue if necessary. Please help.

Seems like a loose solder join. Desolder and redo it.
 
Yep, possibly where the ground wire is soldered to the pot. Those are tricky joints to get right.
I just resoldered the ground and the same thing happens. Could it be an issue with the pickup selector?

I'd add a picture but it doesn't let me yet
 
Also, both pickups are grounded to the same pot (the tone one), can that be an issue?
 
It could be the switch but I agree it's a solder somewhere. Go back and check em. Touching a wire and coming back on is sign of a bad solder.

You're at 3 posts. I think you can post pics now.
 
Had a similar thing happen to me a while ago with a strat, went over all solder joints, and found a bad joint where one of the ground wires connected to one pot.
 
If you're 100% your joints are good, then the switch is bad. Gey a new one and start fresh.
I have one on me that I ordered a couple of days ago, but it is completely different and I don't know how the wiring goes. I tried mirroring what was in the selector I currently have but it didn't work.
Here is a picture of it: https://imgur.com/wKdrgFg
 
I can. Here are the pictures.

No offense, but I wouldn’t trust any of those solder joints. Too much solder in “blobs” that could actually not be making the intended contact (instead of smooth solder joints), melted insulation, and several places where a stray strand of wire could be shorting. Not sure of your experience with electronics soldering, but here’s a good tutorial, with good looking solder joints:

I’ve “soldered” everything from wire chambers (wires thinner than a human hair) to very heavy copper wire carrying 50 Amps (I created some real metal sculptures) it takes some time to heat up the back of those pots for ground connections.

Even with years of experience I mess things up, usually because I’m not being patient/careful.
