Hi, today I was driving around in the woods for a while and as the sun went down it got chilly so my buddy turned on the heat and all the sudden all the windows and windshield fogged up real bad. We cracked the windows open, turn the heat up and down, wiped the windshield a couple times and wait for a while but nothing worked, it was fogged right up tick.

Any idea what can cause that? I have good heat, not burning heat but good and I noticed a slight coolant smell a couple times before. A/C is not working anymore. Looks like the blower is blowing out humid air to do something like that.

Thanks

 

Your heater core took a dump on you, bummer man. That antifreeze on your windsheild. Dash has to come off to access the core. May as well look at the evap core while your in there, at least inspect.

 

Damn, I was hoping for some stupid to fix but in the back of my head I knew it would come down to this. So the core is leaking internaly and blowing coolant in the windshield?

 

So how do you know if the evap core is no good other than if it's rusted or some like that?

 

I would replace it anyway., They are installed together. If you go through the work to do one, the other will take a dive two weeks down the road....(my luck, the next day...)

 

Yes I plan on replacing it anyways because a/c is not working and it's probably part of the problem.

 

A/c evap will have to wait, too expensive. Any ill effect to not recharge the ac? And how about removing the whole system off the truck?

 

Job is done and it falls in the category of, jobs I don't want to do twice.

Bottom of the HVAC was full of coolant. A/C evap core looked fine to me and the system still had pressure in it so maybe it was just too low to refrigerate enough. We will see next summer when I will recharge it.

Anything I should do to the A/C system because it's empty now?

 

Did you disconnect the AC evap core too and remove the whole HVAC box out of the truck to replace the heater core?

 

Yes I did, is there another way to do it?
