after I changed myweaterstripping of My T-topped car, I found out that the new seals leaked everywhere.
now with the help of some sealant I was able close up most of the waterleakage.
yet I still havent found why both sides of the carpet ( passenger and driver ) are wet ( almost soaked ) near the feet.
the water is comming in from somewhere I just cant seem to find how it enters.

I know its not the heater core.

 

Did you bridge the gap from the A pillar to the roof? The yellow "C" is where I'm talking about only on the A pillar. It needs to be bridged with windshield rope caulk. There is one of these on the B pillar also which is shown in this picture.

 

I thought I did, but now I did, I also did the complete A pilar ( even behind the bar where the weaterstripping goes in. and I just redid the same part on the driverside 2.

Just saw that the passangers side is still leaking in somewhere

 

I have the same problem with my 91 z-28. The water is getting in under the hood, where the wheel well meets the firewall. It rusts out in the "valley" and you can prob. stick a long screw driver down through that area and see it from the inside. At least in my car you can

 

nope, passenger side is coming from the roof found it and sealed it. ( I think )

drivers side, looks like there is a hole in my front inner fender ( where you can put 4 fingers in ). the water gets swiped pwarts against that hole, and it flies against my firewall insulation where it and then gets down to the carpet.
