2003 Tacoma; interior leaking into floorpan on drivers side only.

I have an occasional to regular water leak into the interior drivers side of my Tacoma. The water pools up in the floor pan and I get to sop it up with full size towels. And, then I get the occasional horn shorting out for a really long burst, until I'm able to pull over and yank out the fuse. When there's no more heavy rain/snow, no problems.

I've seen some posts in reference to the '05 Tacoma having a similar leak with an associated TSB, but nothing for the '03.

Any ideas for a fix? Or, does anyone have an repeated instance?

 

i have an 03 and my windsheid leaked from the top
lift up the hood and check the area around the windsheild for rust or something might be cloged under where your wipers are

 

Yes, it usually leaks from the windshield area, but for me, it was leaking where there grommet where the wires come through the firewall from the engine compartment, check there too.

 

Thanks all for your input. The leak did turn out to be the firewall gromet; accessory wires run through it (prior owners doing). anyhow, half a tube of black permatex...no more leak. (knock on wood)
