There may be a leak in your heater core inside of the care. This would cause moisture to be blown up onto the windshield.
Take the car to a mechanic to verify this.

I have 94' standard Trans mission my defroster blows a fog and I think its a coolant fog what could be the problem?

If the fog is oily, then your heater core is leaking and the blower is blowing coolant onto your windshield

When my car turn on start switch...eng running. I don't turn on a/c switch but compressor pully and clutch are running together Is it ok or problems? Car is BMW e90. 323i 2010 year Thank you

Is the heater control in the defrost position? Most cars will automatically turn the air conditioning compressor on when defrost is selected to dehumidify the air being directed on the windshield. This keeps the windshield from fogging up, and helps defog the windshield more quickly if it is already fogged up.

1998 Nissan sentra ac bypass

Assuming that it is working in frigid conditions, sometimes The
Ac works with the defroster to remove moisture and the fog on the inside windshield. So, turn the defroster of unless you need it when the windshield fogs. You may be able to keep the window clear by opening the outside air vent and increasing the heater temperature.

Fog goes away when i turn on heat. windows fog up from top to bottom. that means it is not a heater core

May I assume you've tried the 'defrost' setting? Front or rear windshield? I'd be looking at control to turn on 'defrost'. As for the in/out, there's an inlet and outlet hose to the core.

I have a 2005 chevy malibu LS, 3.5 eng.when i turn on my defrosters the air cond. comes on with temp control on heat also have a message on the message center {RADIO} how do I clear this message.

It is normal for the A/C compressor to come on during defrost mode. This is done to prevent provide dry air to the windshield to prevent fogging when the defroster is turned on. The blend door is designed to allow heat to the windshield, but also some of the cool air from the evaporator to prevent fogging.

Windows fog up

There is too much moisture inside the cabin. Either something is leaking water into the car, or your fresh air setting is not working on the hvac system. You can not run the system on recirculate and get rid of the moisture.

My car smells like it is overheating but does not and the windows fog. when i put my windshield defroster on, it takes a long time to do anything and sometimes the fog gets worse.

it sounds like you have a heater core leak. If it smells sweet and the floor is wet on the passenger side, it is a leaky heater core. Costly repair.

Front window defroster note working

Was there a smell along with it fogging up the window like antifreeze? If it did the heater core is leaking and needs to be replaced. It will be kind of a sweet smell.
