Water on driver's floor

So get in my '98 Jeep Grand Cherokee this morning to go to work. I start it and the radio speakers are nothing but static. I turned the radio off and STILL static. I get to work and find my driver's front floorboard filled with water, about a 1/4 inch above the carpet. I've had no problem with water getting in. I've been through car washes, etc with no leaks. It did rain pretty heavy last night though. I got home tonight and figured out the area under the driver's side rear seat was filled with water too and apparently the amp didnt like it. I unplugged it and all is quiet for now.

Where should I look for leaks? The Jeep was parked on a driveway with about a 45 degree incline facing up. I have a sunroof too. Its been through car washes several times and I've had no signs of leakage anywhere.

If it's the driver's side that's wet, it more than likely isn't the heater core or plugged ac drain line. Those normally cause the whole passenger side to be wet. Your best bet I think is to use a hose on the outside to see what is leaking. Obviously, do this an a day when it's above freezing.

Yeah, Im thinking with the angle to driveway is on water overflowed into something that allowed it inside. Is there any kind of drain on the driver's side that could be clogged?

Did it rain or snow where u are? I had water on my driver side floor the other day due to the snow melting. I think it came in from the lower part of the windshield seal then under my dash and dripped onto the floor. My ac only flooded e passenger and rear floors.

I've got the same problem, luckily for me, winter decided to warm up and rain, then freeze the flowing water to my floor pan. The culprit is my weather stripping for my door, it's torn and there was a little river of ice right down to the floor pan.

On the ZJ there is sealer on the cowl seam a that you can see at the lower corners of the windshield. This seam continues under the black plastic piece that covers the cowl area. This sealer can crack and then you can get water under the carpet on either or both sides. Also the torx bolts that hold the roof rack rails can leak and sometimes need to be resealed. Look up under the instrument panel with a bright LED flashlight, look for dried water stains on the black insulation. Finally the windshield seal can leak too.

I'll have a look see at those when it warms up a bit. No sign of leakage on the headliner so I'm going to count out the roof rack bolts. Thanks!
