There is only one possible cause to this easily diagnosed symptom. Any mechanic will tell you: the heater core is leaking. This is why the steam is rising up to the windshield, and why you are smelling coolant. Your heater needs to be replaced. There is not quick fix, just replacement. Hope you can get this done soon. Heater cores are nice to have during winter weather. Steamy windows aren't easy to see through, and are hard to defrost! Thanks for the question. Good luck. TT

it is on the fender near the battery and is also referred to as the starter solenoid (if you follow the large wire from the positive terminal of the battery at the other end will be your relay/solenoid)
hope this helps!

front of engine down low on passenger side (access from under the car), there is no AC delete option so the compressor should be there and not bypassed, what is the question about the AC? it doesn't work?

you could have. Take a look and find out. If the lid/cover of the fusebox does not name the fuses and relay's check owners manual, find the fuse(s) and/or relay and check it out.
Relay can be tested in a few ways,
first, easiest way get a buddy to go in the vehicle and switch your AC on and off, find the relay and get in real close and listen and feel for the relay clicking as he turns it on and off, if the relay is clicking it is most likely working fine.
if you are unsure on relay working you can try this method: theres usually 2 switches one is normally closed one normally open. Using a multimeter and the electrical diagram that should be on the side of the relay itself you should be able to figure out which switch is normally open and which is normally closed. Look carefully sometimes the writing, labels and numbers are hard to see.
Another possible cause is that your temp sensor failed so the computer thinks its -40 degrees and therefor won't run the fan. check the temperature sensor wiring, and the sensor itself after you look at fuses and relay operation.
Hope this helps :)

you may need to top up the coolant,r112,r140or what ever the car is useing. if the car can'nt be topped up then you have a leak that needs to be fixed,usually the drier.
