What's up fellas. Well winter is here. My front windshield gets so humid then freezes cause the weather. But this is on the inside. The other day I was with a scraper on the inside scraping the windshield. I just came from work the car been sitting for 12 hours. The inside of the front windshield was like when you come out the shower and the mirror is fogged up. My heat works but takes a bit to kick in. But this is internal ice. Rear glass gets frozen on the outside. Doors glass ok. Any suggestions?

 

Run AC and high heat for a while with the air on recirculating. You have moisture in the car, just need to dry it out.

 

Thats very strange. I've never heard of anything happening like that before.

 

Either you have water leaking into your cabin area, or you have recently left your window down during a rain storm.<--ask me how i know this one..

To start, check your carpet area for water/moisture.

 

spare well too... i had quite a bit of water in my spare well last year. During the summer it stunk something serious. It never progressed into the winter. so i never got to see it freeze or anything... but it was enough to where the steering wheel felt a bit damp, and really, all the air inside the car felt damp.

 

just had the same problem i just let the car warm up with the defroster on. my floor has been damp for the last couple weeks cant figure out why though. i know my trunk leaks but that does'nt explain why the driver and passenger side of the floor is damp.

 

check youy heater core, it could be leaking causing moisture in the cabin

 

um, no.
put it on defrost. That activates the A/C and the heat for the windshield along with fresh air.

The A/C removes moisture
The heat melts the ICE
The fresh air allows the cold air coming in to absorb more moisture.

 

recirculates broken on my car, but worked fine for me...

 

There's 2 posibilities I'm thinking of - and my floor is damp too under the front mats. The rear got damp in a serious rainstorm when I drove for 4 hrs blasting rain on the highway. But, a rusty wheel well in the rear can create a gap near the rear seatbelt anchor (like in the photos for the Rust recall thread) I'm thinking maybe that gap can lead a slow stream down to the rear floor, 2nd: that seal (sealant) along the top of the rocker panel that runs the length of the side - could that feed directly to the front floor?

It would be nice if we could create a short list then in the spring when I rip the insides apart I can test them all.

True on the dampness Greeny - I think that was the cause last winter that created that icy inside window thing - just like the OP had. My carpets were damp, and the dampness must have clung to the windows when the car cooled down.

 

Caped I wonder if the dampness creates a permanent mold in that foam material under the floor carpet. I was looking at your photos closely when you ripped the carpet out - that foam stuff looks like it could get water logged easily. Do you think it would be better to remove it all together and replace it with a harder pink type foam - like house insulation foam? Also I'm wondering if there are any plastic plugs under that foam that could be cracked open.

I ran my heater on full blast for a couple of hrs a couple of months ago pounded the carpets with towels - and the smell is gone. It dried it out completely in the rear.

 

There's no plugs in the floor of the car, but that doesn't mean you can't use a hole saw and add one the same size as one of the trunk plugs to get any standing water out.

no need though if you'll find and fix the leak. that's what you need to do first.


There are many places to check for leaks.
1. rust problems. if there's a hole rusted in the body, you're going to get water in the car.
2. sunroof drains. they sometimes get clogged with gunk and stop draining properly. check and clean as necessary.
3. weatherstripping. it's getting pretty old on these cars and it's possible that it's leaking around a window or door or something that you don't see easily.
4. A/C fresh air inlet. If you've pulled the heater core, you'll notice one of the boxes connects to the cowl and has some weatherstripping stuff around it. When I replaced my heater core, I didn't get that put back together right and it caused a water leak into the passenger footwell. finally pulled it apart and RTVd the crap out of it and put it back together. gone.

 

There are plugs under the carpet, 4 of them... one in front of each seat.

 

Hmmm..... mine were metal ones welded to the floor.

Maybe your car has a history of flooding itself.

 

Yeah, its something I'd rather not have known. This is strange though, they are both 93's. I wonder which one is the odd duck.

 

Well last night I had put the heat on and recirculatator together. It totally defrost the windshield.This morning no frost. Also when I came from work no frost. Did the same thing tonight with the heat and recirculator. Will see tommorrow morning.

Also my front floor is damp the left more then the right. I do have that rust problem.
I wonder if this is the problem for the humid windshield?

 

If it's snowy where you are, it could simply be sludge from your shoes/boots...

I would bet the rust issue is another/the problem. you get water in the car by splashing through the rust holes while you're driving.. if there's holes in the floorboard, you get splashes into the car through them.

 

Agreed - I think the rust issue is the major factor here. As this GXE got older and the rust got worse, the wetness problem started only in the last 2 yrs or so. By the way, I checked the rear seatbelt anchor like in the recall photos, the drivers side rear anchor is completely gone, I was prying it back and forth, back and forth and it snapped off like paper mache. That seat is out of order now. For some strange reason the other side rear seatbelt anchor (from in the trunk) is completely in tact - no rust at all. Now I better check the lower anchor on that side too. It's very strange why that trunk anchor has no rust on it - yet the other one is completely gone.

Do you know where the structural metal is for safety for the drivers and passengers seatbelt anchors - for a quick check I can do? I know the bolt or whatever it connects to near the floor (between side doors) is rust free for both. I don't see any rust on the metal surrounding it.

This GXE is very weird. Other than that wheel well near the fuel filler tube, there's not that much rust on the car. There's rust on the rocker panels, where the salty slush freezes and hangs during the winter - but other than where I see slush would hang around - there wasn't that much underneath. I don't understand how that seatbelt anchor got killed though - could it be salty slush again, getting thrown up there and just sitting there eating away?

 

you have the odd duck



anyhow... OP, i dunno about re-padding your ENTIRE carpet. seems like a helluva chore. In fact Matt Blehm even boasts his STOCK carpet in his signature haha, despite ALL the other mods on his car . but perhaps you have cracked drainplugs.. i guess it's something to check if you feel like diggin into it that far. Btu what you can do, is invest in a dehumidifier like the one i have. After draining my trunk I ran the dehumidifier overnight for a few nights and it stopped stinking and dried up.

 

1. contact nissan about the recall
2. Kick off the slush whenever you see it.

 

Definitely I know the water on the front floor is coming in from the rusted sides. I remember there was a post here with pics of the rusted sides and the weld job he did with pics. I think he was an Org member from Canada.

Also no frost on the windshield today. Did the defrost and recirculator again.

 

JRS - depending on how much work you want to put into your 'ol max, I may be buying a big bucket of specialty grease used in the mining industry - for the ultimate in corosion resistance - so if you are interested in splitting the cost with me (or anyone else on the board who suffers from the road salt/rust problems up north), send me a PM. The huge pail will be way too much for me to buy, so i'll need people to split it with in fact.

 

is'nt there some type of drainage hose that come fom under the engine compartment. i remember working on a ford thunder chicken the had tube like that and i ended up shootin some up there to free the hose of the obstruction do we have a hose like that?

 

The A/C will help dry things out, but the colder it gets out the less effective it is. To quickly get the moisture out of the interior go to Walmart and buy the little buckets of dessicant that people put in damp areas of their house. Buy a couple and close them up in the car. Keep emptying them and in a couple days all will be good.

And find the leak. If its through the floor pull up the carpet and seal everything as best you can. Rubberized spray undercoating will work on the seams. Not pretty, but it's better than wet.

 

wow great thread and jsut one more reason im glad i park in the garage

 

I had a similar problem.

It started the 1st winter I had it, my windows constantly were frozen on the inside...I couldn't stand it. Then the summer following I started to have damp floors all the time (mainly driver side, but soon the passenger side got it too).

Finally I figured out my problem. I don't know how common this is but apparently some how the drains in the area directly in front of the windshield (where the wiper arm assembly is located) got plugged and rusted out that well on the driver side only.

It was just a couple pin holes but enough water came in to make it bad.

I sealed it once but apparently I didn't do a good enough job because it leaked more and then I found that it was also the cause of my car running terribly. Some moisture made its way to my tranny computer and ECU and fried both.

I replaced them out of my parts car and ground out as much rust as I could and filled the area with gutter seal and it has held since.

Weird huh??

 

Today was like 8 degrees. I let the air circulate and ac on so thats been working since I did this post.Since 12/29 frooze up once but very minor. Not like it use to be all frozen every day that I had to scrape it.

 

That's crazy. The rust here is horrible in Ontario. I wonder if that's what killed my suspension tonight.

 

my 91 leaks ,but only when it rains hard.it drips a little rain water where the ac\heater boxes meet . i thought ive seen a thread here about “A-PILLAR” rust causing this type of RAINLEAK
