My parents 91 4runner always blew fog. It just made me think the air was alot colder than it really was.

It happened on dry days as well.

 

Mine does this as well. Yes, i had a bad heater core and a cracked line going into the heater core. Bad luck for me, because i had to pay somebody to pull the dash out of my truck. : \ My a/c blows cold enough, but it still fogs at night and early in the morning or after rain. I don't think any of you have to put up with the humidity of South Eastern Arkansas.....eek. Tim

 

my last car did the fog 95 neon and my 90 mpv as well as my runner all did after service all worked great nice n cold
i live in tennessee

 

Mine did the same thing last summer...light fog out of the vents usually in the mornings. Did it for a couple of weeks and then the A/C stopped working. Man do I ever miss it this week. It's been in the mid 90's with high humidity.

 

Agreed. Can turn recirculate on to reduce or eliminate the fog. May take several minutes to recirculate the cabin air.
