Been trying to figure out where a leak is coming from and I had the chance this evening to start looking.
I pulled the cowl and cowl screen,stuck a hose in there and let it run for a few minutes.

where the floor pan meets the firewall it started coming up thru the seam sealer. Is the firewall double paneled?

if it is then I have to re seam seal the wiper troth and that area inside the cab.

Water is coming thru where the silver sharpie is.

I would remove/pull back the plastic rubberized panel will make for a lot less guess work. Check antenna grommet is pushed into hole in firewall this cable gets pulled during petty much any major dash service. 30 year old truck dash has been out at some point.
