ok so i dont smell any antifreeze or anything but it seems like my truck fogs up really easy, and when its cold out or raining i almost always have to have the defrost on. if i park the truck in the rain of cold and come back in an hour or two its completely fogged up and it seems like my back and side windows are always fogged up but the front one is not cause the defrost. so do u think my heatercore is leaking? also how do u replace one in a 1998 3.0

thanks

 

What are you doing in the truck while it's parked?

 

no if i leave and nothing is in it or anything and i come back to it in like an hour of more its all fogged up......heater in the on position or not

 

since you live in CA maybe the humidity? are you running your ac?

 

I'm guessing this happened when you were getting all that rain the last couple weeks...right?

You have a leak somewhere and water is getting in to the cab, check the back window. Thats where I had a leak coming from.

 

Ya, I think that went right over your head. Moisture is getting inside your truck somewhere.

 

haha i got it but your suppose to crack the windows for that.

 

had the same problem....your heater core is fine

check for leaks in the window seals.
you may be getting water in the cab somehow.....check the floors for leaks

 

i cant crack the windows when its pouring down rain....i dont have a sliding window but il check for leaks.

 

The leaks around the back are normally from the third brake light. mine leaked real bad there and it was the brake light assembly. Happened twice to me and once on my grandfathers B4000.

 

Its part of the cab. It happens to mine. Check this part and run a bead of silicone in it.

 

you still didn't get it. guess you didn't have a lady friend in there with you huh? just fistina?

 

lol.

 

hahahah palmala handerson

 

haha, this thread is great.

 

but seriously window leaks or what adam posted. i would put silicone where he showed in the pic thats where mine was leaking at.

 

Here's a thought....

STOP BREATHING!!!!!!!

 

ROFLMFAO!!!!!

 

ok so i checked my brake light and all dry in there. then a couple of days later i noticed my headliner was wet and it was dripping on my amp/floor. and that it was most wet at the corners where those places showed above. so i siliconed that but only the top half. so days later its leaking again. so i sealed the top and the bottom again really good. than like an hour later it started to rain and it was still getting in there somewhere. i cant see where but my headliner was wet again on both sides. no i noticed on my part thingy that i siliconed it doesnt rap around to the window like his does it ends at the roof and i have just a line where the 2 peices of metal meet and over lap there. i have an xtra cab 2 door.

 

and this my friends is why i probably couldn't stand living on the north coast, rains up there more than oregon

 

it really isnt that bad ....but more rain = more mud

but this water thing is pissing me off

 

bump

 

just because your break light is dry i would take it out put a bead of silicone around it and put it back in

 

98liftedranger that same corner pice is loos on my truck. Should i silicone the crap out of it or what.

 

My 87 was leaking around the bed light a good bead of caulking fixed it though.
