Alright guys, it's been almost a year since this problem, but it's back now. Once last winter left, I completely gutted the interior of my car, and had the floorboards and inner seams re-welded and sheetmetaled, so I know the leak isn't coming from the floorboards anywhere, but water is still getting in my car.

As you know, it gets extremely cold in Michigan, and well, all that water has to go somewhere. My windows keep getting frosted over on the INSIDE of the car. Worse so than the outside. I spend about 2 minutes scraping the outside, and about 5 minutes scraping JUST the inside windshield, but all five windows frost over (The worst is the driver and passenger, and worse yet is the windshield). I also noticed around the window trim on both doors, that there is frost starting to develop on the inside too. (This is when it's say all night and gotten extremely cold). My drivers side power door lock also seizes up when this happens, and I have to crawl through the passenger side and force the lock to unlock before it unlocks.

There is also a puddle of water on my drivers side floorboard in the front. It's not very big, but it wasn't there before. We extracted all the water from the car and carpet when we removed it all.

After we fixed the floorboards and etc on the car, we soaked it with water for about 20 minutes from a hose checking the car for leaks, and we couldn't find any place that the water is getting in, but this may help. Even when the car sits, and we get extremely heavy rainfall, the drivers side gets wet. (Which indicates that for the amount of water there is, it's not coming from below)

I was told to check the windshield wiper area as this is a common area for leaks, but does anybody know how to remove the windshield wipers so I can check? Also, does anybody know how to check for door seal and windshield seal leaks? This would help me alot.

Oh, one more thing. My defroster doesn't work worth a damn to defrost the windows either. It takes quite a bit of time to defrost the windows (When they aren't frosted over, just foggy). I've seen most cars do it in a matter of about 3-6 seconds, but mine takes well over 6 minutes.

as you did with the floor boards, try running some water over your windsheild and check for leaks around your pedal/firewall area. this areas drain can become clogged with dirt & leaves. another area may be the firewall itself. water can get into the conduit that covers wires going from the engine bay to the interior, then it just a matter of when/where the water will drain out.

You'll need to check the windshield wiper cowl and all the firewall area too. That is the source of many interior leaks.

As for the defroster... does you AC work? The defrost mode runs the AC compressor to help prevent water vapor from recondensing on the windows. My defroster hasn't been that effective ever since the AC systems is out of order.

actually my ac system isn't hooked up right now, the a/c hose coming from the compressor is missing and i haven't replaced it yet, however I don't recall it ever working very good, even when the a/c was pumping out excellent.

How does one get the cowling off of the windshield wiper area? I heard under there is a major source of leaks all the time, and would like to see about getting it checked.

EDIT: Doing a little dabbling into other problems on here, it appears somebody mentioned the heater core could be out. Ever since I put the new motor in, the low coolant light keeps coming on, and I have to put coolant in the reservoir. (The water problem has happened since before the new motor swap). Anyone know other signs of a bad heating core? There isn't coolant on the ground where I park, or anywhere after i've pulled out of a parking spot, I have NO idea where the coolant is going. It's got probably 6 jugs of coolant in it. The car heats up fine, and doesn't get over 220 before the fan kicks on, and you can't smell coolant. There are also no problems with the heater working. Also, the puddle on the floor is clear (no green tint to it), and it freezes completely like ice, so I don't think it's coolant.
