#1 of 5 Lincoln Navigator Fan Motor by my3blessings Nov 16, 2007 (8:18 pm)
I just purchased an 03 Gator with 60,000 miles. Just noticed that fan blows intermittent when in vent or AC mode. It will be blowing, then stop for a couple of seconds, then blow again for a minute or so, and continue repeating this pattern. It does this at all fan speeds.   Went by the local dealer, and they told me this was normal. When the engine fan turns on it will cause the inside fan to slow or stop, due to the way this system is set up. The rear air does not exhibit this same behavior, it will run constantly with no variable or intermittent blowing.   Anyone have an idea what is causing this or if this is normal?
#4 of 5 Cooling System Issue by pmenendez Nov 16, 2008 (6:59 pm)
I have a 2000 Lincoln Navigator and receintly replaced the upper, lower radiator hoses. I also flushed the system with new coolant and replaced the thermostat. After all that I hoticed that the heater core was leaking, I went ahead and replaced that too.   Now I notice that when I turn on the heater it blows hot air most of the time. Sometimes it blows out cold air. I have no leaks and the temp gauge stays in the middle range. The coolant is full.   Was I supposed to bleed the cooling system? If so how do I do that with this truck. I did not see any bleed valves near the thermostat housing.   CAN SOMEONE PLEASE HELP!!!!

I have a similar problem, for some reason, I can't get any hot air out of my heater. Please help, I'm freezing my rear end off!
