Moisture problems

blajeans · 10-19-2009, 06:56 PM

Hi everybody, I´ve recently bought a S10 Blazer and it all worked nice but the other day I took a drive for about 62miles on a highway and when I was arriving to my destination I turned in to a parking lot and suddenly in about 5-10 seconds all of my windows where covered with moisture.
Okey, it was rainning pretty heavy so I thought this was just temporary, but here the other day it happened again and this after a 60 miles run on a higway and the moisture attack came when I slowed down for an exit on the higway ... hummm even this time it was raining pretty heavy.
Well I didnt payed much attention to it becuase the car worked correctly so I thought that the rain had caused the moisture attack but last night it happened again and now it wasnt raining at all.
It doesnt smells funny like for example glucos could do if there was a leak in the heating package ... it just starts to moistures my windows

I use my car everyday to drive to my job ... I should guess it´s about 6miles to my job and never experienced this problem on my way to the job.

Hope you guys understand what I mean, Im not sure if it´s called glucos (the liqiud you blend with water and pour in the radiator).

That sounds a lot like the problem that I am currently having. My windows always fog up after a few minutes of driving. In my case in happens any time it is cool regardless of whether it is wet or dry out. In my case there is an odour in the truck, but not a strong.

I have been told by several mechanics that I need a new heater core. This is an all day job. Hopefully your problem is something a little cheaper to fix.

+1 for the heater core.

Mine used to have the symptoms you are describing...plus reeking of DEXCOOL after a while.

+2 heater core, suppose to be an 8 hour job, took me two days.

My heater core is just fine, the owner before me changed it about 5 weeks before I bought the Blazer. If the heater core were broken, shouldn´t I discoveres coolant in the coupe?
Is there any way to get the AC working all the time? I figured out that my problems only appears when the temperature drops below 42°F and at this temperature my AC turns off. Tod ay I tried to turn the AC off and then moisture came directly, turn the AC on again and the moisture dissappeared.
