Question about 2005 Ford F 350 Super Duty
What is causing this smell. If I turn of vent it is fine, but if defroster or heater being used, it smells like the exhaust is pumped into cab.
SOURCE: Burning smell when ac is turn on
well as for the ford man sorry to here that. I am a holden man myself, but it is most likly that your fan switch is on its way out if you have a test light just pop the switch out and see if you have power to your high setting if not replace your switch. And for mgauthier I would suggest you just reroute your overflow pipe so it overflows onto the ground not onto hot metal parts. But you shouldn't have coolant coming out your overflow all the time. As for burning smell it was probably the switch burning out and failing.

the small radiator just inside the cab, where the hoses go to the heater is leaking. You may try using stop leak (many don't recommend this) or take off the heater radiator. it will probably get worse when you turn on the heater and fog up the windshield if not fixed. hope this helps.

I had the same problem in my 98 Dodge Dakota! Replaced the heater core, problem solved. No more funky coolant smell and erie fog coming through my vents. I bought the heater core at rockauto.com online. Have purchased many items now from them. All factory parts so far at half the price of even AutoZone, even with the shipping. Also, you usually have to wait only a couple of days depending on the part and they have EVERYTHING.

This is definitely a heater core issue, but I might also suggest one of the many over the counter cures first before replacing it, the heater core is not a very expensive part but quite a chore to replace.

The block heater is already installed in your 6.0. The cord may not be there as it is an option in some states and standard equipment in others. The best way to see if your cord is there is to crawl under and look up by the # 4 cyl and you will either see 2 prongs sticking out for the cord or you will see the cord. The cord should end in the front bumper behind where the front tag would be. If you dont have the cord Id suggest getting it off ebay as it should be cheaper than the dealer. Hope this helps.

Sounds like an exhaust leak either at manifold or collector pipe. Exhaust is being sucked in through fresh air intake for hvac system. Must scan to determine what code is setting check engine light.
