Need assistance with ideas for squeaky dash. Not in instruments. on 1997 Mercury Grand Marquis

Worse at low speeds. Attempts to push on dash here and there to stop have been unsuccessful.

I guess you have already emptied the glove box.?. Passenger side, center or drivers side?
Yes. Sounds like it is higher in the dash. Thanks for asking.
It may actually be comming from under the hood back at the firewall. All we can do here is guess!! Unless it's a known/common problem. These noises can be a pain to find.
