Hello razzamatazz2: My name is Roger and I will help with your problem. You are smelling a sweet smell and the windows fog over. The fog is slick and hard to wipe off and smears easily. You have a heater core leak. The only way to fix the problem is to replace the heater core. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

When running heat or defrost, the drivers side of the windshield will fog up....no leaking coolant or antifreeze smell.


Many times there will be no smell or leak noticeable . sometimes it is just the difference between the inside and outside air .

I have a 2004 Dodge Dakota inside widows fog up no leak in passenger side floor board but defroster clears the windshield in the center so you can drive and all windows will fog


It does sound as though you have a coolant leak causing the fogging. Do you get a sweet smell from the heater vents? That's a dead giveaway. Often the coolant does not get to the floorboard if the leak makes it to the A/C condensate pan. Then it just goes to the ground thru the firewall. Watch for loss of coolant in the system. If you have an appreciable loss, then you should look at the heater core as the most likely cause.

My 2001 jeep grand cherokee has a dark mist/smoke coming out of the vents, and defroster. But, the heater works fine. What could it be?


DO NOT USE STOP LEAK!!!!!! That stuff has no brain so you cant tell it to plug only specific leaks. It will go for the easiest hole to plug which can be a water port in the cooling jacket for the cyl heads. replace the heater core. Fix it right or bypass but please please please do not use anything that will stop a leak

I first noticed this smell of oder coming from my vents without the air or heat on ..then it started leaking antifreeze mixed with water they think could this be a leak in the hose or another problem ?


Step 1: check to see if there is any leakage of coolant under the car, if so it could be a leaking hose or water pump seal.
If not
Step 2: check to see if there's coolant leaking on the passenger side fire wall (inside the car) and to see if there is any fogging on the windshield when the defroster is running, or if there's smearing on the windshield, this would indicate the heater core is leaking and has gone bad.

Heater immediately fogs all windows and there is a sweet odor in the cab of 2003 Buick Rendezvous, defroster works fine, but will not clear the windows after heat is put on


Sounds like a possible heater core failure(hole in it) the smell indicates to me the coolant(anti-freeze) is leaking into the passenger compartment.
Check the carpet in front of the front passenger seat for moisture, this would confirm heater core leak.
Good luck !

Leaking anifreeze and gets hot but not from radiator causes windshield to fog up smoke coming from passenger side and seems to be leaking from the middle of the truck


Do you have any coolant on the passenger side floor board? Coolant causing the radiator to fog up is a symptom of a leaking heater core.

Leaking water from front passenger side, under dashboard


It is either condensation water from the A/C unit that should go out a drain tube to the outside (only if A/C or Defrost is on) or a leaky heater core. If it is a heater core you can usually smell a coolant smell and the water will be warm and your windows will fog up inside. Heater core is more common. Joe ASE Master Tech
