Im not sure how this works with our vehicles, but if you want to prevent the buildup of moisture on your windows, you need to run the A/C too. The moisture in your vehicle will condense on the A/C heat exchanger in your evaporator.
I dont know...stupid post. Your fan is working fine? Our A/C controls work via vacuum...the woosh you here when you flip the lever, does it go away after a sec? Maybe the "vacuum cup" that lets the coolant flow into your heater core is wasting away.
At this point I should probably delete my post and save face but we'll see how it goes.

I have a 180* thermostat - not a 160* but I never have an issue with heat - generally it is TOO hot. The only time it didn't get hot is when my heater core took a crap. If it has taken a crap your windows will all be fogged up. I don't know what physics apply to the windows being foggy when a heater core dies - but it happens. I would guess that is your issue - but you should also have a very foul smell coming from your interior that smells a little something like anti-freeze :smile: It could be outside the truck in which case you will see anti-freeze on your passengerside fenderwell area. I have driven my Ty in temps below 0 and had to turn the heat down.

Right on. If a vehicle has A/C, it will be used by the defrosting system to help remove moisture. So, just turning on "Defrost" actually turns on the A/C (as needed). My guess is that your A/C system is not functioning and you have a problem with anti-freeze flowing to the heater core. My A/C is blown right now, but the heater is hot enough that moisture doesn't get too bad, unless it is really, really damp out and my girlfriend is talking alot :smile: .
If your heat (when you have the little slider bar pointed to heat or vent) isn't working - meaning COLD/luke warm/chilly/ - it isn't going to have anything to do with the AC compressor. The AC compressor only works on AC and defrost. Which I think was stated - I just don't want to pass that point up and make this more difficult than it really is. I disconnected my AC compressor and my defrost still got hot. I think all the AC compressor does is removes the moisture from the air - it shouldn't keep it from getting hot. Check your coolant level as well. Not only at the over flow - but at the radiator cap as well. Chances are if it is low - it is going to cycle between hot and cold.
Do it yourself - 3 hours with http://www.sytyarchives.com instructions. They aren't as entertaining as Ivan's - but they will get the job done.
Yes - get a 5/8 inch adapter thingy - I have no idea what it is called. I got a brass one and just disconnected the two hoses going into the heater core then attached those hoses using the adapter thing. But in that case you will have NO heat - period, zilch, nada. But you won't have to worry about your windows fogging up.

Aaron,
Thanks man. I just couldn't figure out why my defrost/defog works great all the time except it seemed when my girlfriend is with me....I guess I just never put 2 and 2 together.:smile:
