I think I know the answer, but...
A while back, my A/C stopped working. No matter what I got heat. I live in SoCal so heat isn't really a huge issue (except to unfog my windows in the morning). Now anytime I try to use it (heat or cool) only heat comes out and - no other way to describe it but - fog comes out. It's really think like smoke - the first time I thought my truck was on fire!! - but there's no smell and it hands around for a long time and fogs up the windows. There's a plastic housing under my glove compartment that gets HOT anytime I drive, but especially when I gave the A/C a shot.
What does it sound like? Is it a relatively easy or at least a "doable" home repair?

Thanks for any info/input

 

your heater core is clogged/cracked and the antifreeze inside the cabin is fogging your windows. change a heater core is a pain in the ***. good luck

 

pin hole leak will do it as well

 

Thanks - that's kind of what I thought, but wanted to get some expert opinions.

 

the dash aint all that bad 4 bolts at the top drop the steering colum and two bolts on each side and its down takes the techs at work about 45 mins to take out and another 45 to but it back

 

1 1/2 hours for the whole heater core swap out? So, not being a tech but being able to handle myself, maybe 2 1/2 to 3 hours?
Or am I misunderstanding something?

 

Just got my 00 Dodge 1500. I Have the same problem. When I blow the heat smoke comes out just for a few seconds and then it is fine. The AC works great. I wonder if I have the same problem.
