Hey guys, got a wierd issue with my 90Iroc. Everytime i go to stat up the camaro to work or after its been parked a few hours i notice all the interior windows are iced up bad. Especially the rear hatch and the drivers window. Oh im up in clagary alberta and its been -20C for the past week, haven't noticed this before.

The heater core works fine, don't seem to have a coolant leak, but the weatherstriping is in kinda crappy shape. Thing is i've driven lots of vehicles over the years up here and at times left a window open but even then they didnt ice up nearly as bad.

Anyone have any idea's what could be causing this, I'll probably repalce the weatherstriping next week hopefully but i doubt it's the problem.

 

just wondering, do you have t-tops?

 

Nope, it's a coupe.

 

They're icing up because there's moisture inside. I know what you mean I live in ND which hasn't been -20 yet but I'm sure it's coming soon. If there's leftover moisture in the air from you being in it or whatever when you get out it freezes. You could vent it out by leaving the door open for a few seconds extra when you get out, but don't know what else to tell ya.

 

Now I remember why I don't miss winters in the midwest.

 

evaporator?

 

must have a leak somewhere. Possibly around the rear hatch.
