i have water leaking inside the dash, i drove in the rain for about 4hrs, and water is getting inside the dash. Does anyone know what i can do? or where is getting in from? maybe the windshield needs to be sealed? i have no idea.

 

Put your car details in your signature line. I don't remember what you have.

Are you losing coolant? There have been incidents of leaking heater hoses inside the dash on the 3.2 TL's.

If you're sure it's rainwater, I would investigate possiblity of sunroof drains becoming blocked and spilling water into the cabin. Usually drains from overhead but might get to the dash.

I have heard of cowl drains blocking and causing leaks into the dash area, but not on Acura TL's. Easy to check. Run water in cowl and make sure it's draing away very rapidly w/o buildup (look down into cowl drain volume).

Only other possibility is corrosion pit allowing leakage into cabin, cracked windshield or leaking seal job. Has it ever been replaced?

good luck

 

I have a 96 2.5 TL

 

My 3.2 was leaking as well. The drains in the cowl had so much mud built up that water would just fill up in there until it leaked into the cabin. I took the wiped arms off, a.d removed the cowl, and shop-vac-ed the crap away from the drains. Took me an hour. No more leaky.

 

ill have to try that. Thanks for the help!!
