Car Heater causing window fogging
Anyone know why a windshield would start fogging up when using the heater in a car? It just started happening on my mothers car a year ago. She also says that there is kind of a fishy smell too.
Any ideas?
I tried using a window cleaner that is supposed to prevent fogging but it didnt work.

As for the fishy smell -- maybe some sort of oil issue?!
Now I guess they should have banned me rather than just shut off posting priviledges, because kickaha and Amorph definitely aren't going to like being called to task when they thought they had it all ignored *cough* *cough* I mean under control. Just a couple o' tools.
Don't worry, as soon as my work resetting my posts is done I'll disappear forever.

To make sure
1. Is there an odor of coolant from the vent.
2. There may be coolant leaking on either the floor mats, or there may be a drain on the engine side of the firewall.
3. A rad shop has equipment to pressurise your coolant system. If there is a leak anywhere this will find it.
Good Luck

Turn the air conditioner on when defogging.
Most AC systems run the compresser during defrost independent of the outside air temperature. This is done to dry the air to make the defrost operation more efficent.

Clean out and dry the defroster ducting. It has some stale funky water in it, so when you turn on the defroster you send hot extra-humid air straight onto a cold windscreen and it condenses instantly and won't go away until you physically heat the glass enough to dry it. You also need to find and seal the leak so the water won't get back in.
I have a similar problem in my old 911 whenever I go thru a deep enough puddle. But that's because of where the heater air intake is. It gets hot enough to dry out the ducts really fast, but it still leaves a couple minutes before the windscreen clears up.
I will try this, thanks

um...ever hear of the defroster? use it
I believe the correct response to this is.............duh
She is blowing the defroster on high, this only started happening last year.
Weather is cold outside, she turns on the heater and the windshield fogs like crazy. I can see a little fogging, but the heater is plenty hot and there shouldnt be that much fogging.

That was my first suggestion to her. Would you believe this car has no way to change this? Its a 1987 Chevy Celebrity and there is no fresh air/recirc switch.

I work in the radiator industry. You probably have a leak in the heater core.

I believe thats what her mechanic suggested to her, but he wasnt sure and she didnt want to pump too much money into such an old car unless this was a sure fix. I will have her go for a second opinion. Thanks

well you said when you put the heater on. not the defroster. sometimes solutions are pretty simple.

Have you mechanic look at your heater-core. I had the exact same problem with my old Bronco II. The heater-core is underneath your dashboard and would be causing this problem. The fogging isn't air, its actually antifreeze, thus explaining your weird smell. My repair bill was around $100. Good luck.

Dave, if the repair comes out to only $100 my mother will be ecstatic!
