No defrost heat/ passenger floor wet?

Not sure if theyre related or Im just piling up issues.

I dont drive the car in the rain, or much at all. But it did rain a bunch recently and my weatherstripping is not complete. I noticed the passenger floor front and rear was wet. It didnt smell like coolant. I folded the carpet back. all 4 sunroof drains ran out the bottom of the car. I sprayed the car down, front windshield, sunroof, and doors. nothing new wet. I turned the heat up and put on defrost with car idling temp got to almost halfway/normal temp. defrost wasnt even warm. I put a hand on the heater hoses near firewall, both were warm.

I bought the car in the fall, havent put a lot of mileage on it to know all of its issues yet. but it made a 4hr trip without overheating. but coolant didnt look great.

Body seams tend to cause impossible to find leaks I've found. I had a hairline crack in the seam under my trunk lid that would fill up my rear quarter panel in a drizzle. Took me forever to find. Unfortunately I don't know any way of finding these leaks besides tearing your interior apart and and spraying down the outside of your car. also sunroofs SUCK

i pulled up all of the passenger carpet, dried it as much as i could. Drove it around at temp with defrost on. its warm at best. but nothing draining from the dash, its supposed to rain tonight so i left it out. i did clean some tree junk from the cowl corners. so maybe it backed up from there.

its the red paint color...attracts moisture...jk lol cleaning out the drains helps a lot...also the moulding just about everywhere rots...if you do find moisture again, feel upwards of where its wet and you should find it...my fc it took me forever as its super dry here...was leaning back in my car to nap and it started raining hard...found leak fast as windshield had (during install who knows how long ago) slipped down just enough to have slight crack, not visible outside the car and let in just about every bit of water it could lol...was fun drive home!

So it did rain a little last night. small puddle behind the seat mount.



I think I know what happened. This little guy used to have a piece of tape covering it. BTW is this missing a piece or did it shrink.



We had a bunch of rain a week or 2 ago, and I didnt even look at the car. I knew it was probably the sunroof but I couldnt explain why it was on the passenger side and not the drivers. Well I was parked in the street and it slopes to the passenger side, so it would leak to the headliner and it would travel one way.

The only thing Im not sure of is how the front floor got soaked with that front seat mount, unless it got through the seams somehow.

The defrosters I guess just suck

That gap in the rear of the seal is there by design. All moonroof equipped S14(s) have that.

Gap is nooo good. The seal shrinks over time and makes it a massive gaping hole... fix it... i glued some round stock in there..then covered that with spilt rubber vacuum hose, some sand paper to get the perfect shape and mint sealage!(sp)

think you would be better just sticking the garden hose into your car and running the water with all those holes lol! but seal those up and for the heat check your heater core operation and your position selector

It sounds like your heater core is clogged. Happens a lot on older cars they get gunked up and the coolant doesnt flow through correctly.

They may be unrelated, if the wetness was not coolant. I would suspect heater core though because your symptoms go hand in hand. Heater core job is not very fun but it is doable even for the novice.

yup...if you cant back flush it with garden hose just remove all bolts from dash and take everything off it as well then you have some more fun stuff to remove under the dash...had to do it on first 240 and took a full weekend...with experience on them I'm sure I could do it a bit faster
