My car leaks water in the front driver and passenger side floor pan everytime in rains. Where would be leaking at? I know my dew strips are in bad shape with some areas missing the outside rubber. Windshield? firewall seal?

most likely the seals on the firewall... check here..

this is a common issue on all of our berettas unfortunately

Ok, I'll try that first.

2nd that, just redid mine for the second time. I swear some of the old seam sealer just falls out. Don't put any trust in the factory stuff and redo everything in the cowl area.

Im removing everything right now so i can seal and paint the engine bay

the seams are really weak once they get old. my 94 was letting water in on the fire wall and it couldnt be traced to the engine bay. i eventually, went under the dash, pulled away all the noise buffering material, did ALOT of , scraping, cleaning and drying. i followed a rusty water stain trail all the way up the wall on the inside of the car. did a thorough silicone job, let it dry, and did plumbers putty over that. yes i know that isnt the proper way to fix the issue but it worked for me. i have since sold the car but as far as i know it still doesnt leak. i put all that down because after all the reading i did when working on it a couple years ago, none of the solutions EXCEPT for breaking everything down and professionally redoing the seals, fit my particular situation. it takes alot of time, trial and error, and investigation to find the source and rectify the leak.

if you have the resources though......break it down and do it right.

Well i have a hint of where the water could be coming from on my passenger side since i found all the rust to be on where the wiring harness for the ecm goes in, however i have still to find my drivers side leak lol and yeah, take everything dash and firewall related out. So i can properly seal all of it!

Typically, you can access the leaky seams from pulling back the carpet and jute-backing and just reaching under the dash. It probably isn't necessary to pull the dash itself out, unless you are too big to fit underneath it. Of the five I've had, only my '90 Yellow Indy has had the dreaded firewall leak yet. Yet. Yet.

I welded mine up in the worst areas, particularly because I actually had a crack or two forming in the sheet-metal, but a good-grade silicon or roof-flashing adhesive like Dap makes is sufficient to seal it up -I personally like the idea of Butyl Tape, because it stays flexible and tacky for decades. I did a small write-up about my repair on here last year...

Good luck people.
