Anyone cut through cowl? Pool in passenger floorboard

anyone cut through cowl above fresh air intake? I have caulked every crack and hole around area of pass. side cowl 03 taco

 

Don't cut through the cowl

 

Why would you it makes no sense.

you have ruled out AC condensation??

 

I spent a long time trying to fix a leak that I thought was coming from that cowl seam, but ended up being from the windshield seal.

Next time you have rain coming, stuff a bunch of paper towels around the A pillar, door panels, and around the firewall on the passenger side. Then check which ones are wet and you might find that the leak isn't coming from the cowl seam.

 

Thanks for posting that pdf. My truck doesn't leak but I didn't know about that.

I usually suspect a leaking windshield or clogged ac drain. Or a sunroof drain if equipped, not sure if 1st gen/best gen had an oem sunroof.

 

I have checked cowl seam & pulled pass. fender sealed all around top of fender at cowl I am at wits end with this f-ing thing water seams to be coming from same damn place a few of my old 90s cherokees leaked.at fresh air seal around plastic stub rising from bottom of cowl canal.I have watched it many times drain down fenderweld kickpanel connection.carpet molded& going to remove.if you have any other ideas love to here them thank you.

 

I ordered a borescope to run it down cowl first

 

Mine was leaking on the driver’s side in multiple places. The a pillar was wet, the windshield and inside in a seam down under the wipers. I used a spray that I could only find at Lawson Products. It’s called leak check and you can get these really long spray tubes that can reach places you can’t see. She’s all sealed up now. I chased that leak for two years. Good luck!

 

Have you looked where the antenna coax goes into the cab ?

Water gets on the Coax surface tension holds it to the coax it gets into the cab.

Does this only happen when parked or only when driving ??

 

thanks.
