Rattle coming from under the dash

[Paparock1]

I have an annoying rattle going on from under the dash.
I have search this site for information but what I have found and tried has not fixed my rattle.

If I add a little pressure in an up or down motion in the steering wheel a lot of it goes away, but there are a few others in different locations behind the dash. I have the lower part of the driver dash panels (at my knees) removed and have been driving around sticking my hands up behind the dash and instrument cluster to feel for vibrations while driving but it really hasn't helped me at all.
I normally just crank up the radio but I am at a point where I just want to fix this annoyance.

Anyone have any ideas or things that have worked for them? Thank you in advance

I've found some wiring that jiggles/rattles on crappy city streets.

Could also be gremlins. They love to piss people off.

Turn signal relay not in its clip? Maybe something that fell into the defroster duct?

Try putting a bit of thin self stick weather strip behind the panel screwholes when you put the panels back on. That should help eliminate rattles one by one as you search them out. Also just try and snug every fastener you see under there. One or two could be a half turn loose causing the issue.
Also let someone else drive around while you reach around and under to locate the noises so you can focus on finding them easier.
