Go to this site. I just fixed mine a few weeks ago. This is great step by step instuctions. The problem is the blend door actuator. I bought mine off ebay for $41. The model is a DORMAN 604-202 (at least that is the one for the 2002, go to the dorman website and look yours up).
Last year I would have to accelerate as fast as possible to get the heater working good enough. This year that doesn't do anything and the temperature gauge never goes above the halfway mark.
Any ideas??
If that's not it, you may have a blockage in the lines somewhere else, crimped heater hose, obstruction in the heater core, but something is blocking your circulation of the hot water. There used to be a valve that was vacuum actuated in the engine compartment, near the firewall, if I recall that cut the water off when cooling was requested, and opened up the hose to the core when heat was needed. Not sure if they still used that in 01. Check the heater lines and see if they are all straight and clear. If so, take them off the nipples at the firewall, so the heater core is opened up, and try blowing through the core. I'll bet it's plugged up.
The bad news is, if that's the case, you may need to replace it - and that's an all day job, for a mechanic!
Failing all of that - the only things left would be a failing thermostat that isn't closing enough to heat up the engine, but you said the heat gauge is mid-range as it should be, right? That leaves the water pump, either being worn out so the impeller isn't impelling the water adequately anymore. Odd, but possible. Or, your belt is slipping enough to not turn the water pump fast enough to circulate your water through the heater system. Another messy job to check, and if I'm right, replace. If you check it, you may as well just replace it, it'll already be out.
Best of luck! It's a good car, even in the golden years.....

The speed malfunction in the front blower switch could be the BCM again, a bad switch, or a bad fan motor. Hoping it's the motor, and very likely could be. But combined with the window issue, I'm liking the BCM more all the time. Has this car ever been flooded?

Any help wold be much appreciated as well as put problem to rest and most of all , (from my wife words) "please help its cold going into work"
To replace the blend door the heater case will have to be removed from the vehicle after the dashboard s removed & after the a/c system has been discharged & disconnected at the firewall. It's about a 6 hour job for a pro.
Don't recommend you do this unless you are very well mechanically inclined.
I have a 2000 Ford Explorer fully loaded. It has the Climate control system, and when I turn on the heat using the AUTOMATIC button, instead of like, the FLOOR button, there is a fairly loud hum noise, and the electric system seems to bog down...if i hit the FLOOR button, it stops.... this all while i have the temp set at 90 degrees....seems to only occur when hitting the AUTOMATIC button.
the sound is kind of a low hum...almost like a soft noise a car horn would make if the battery was about dead....
Let me know what you think or if you need more info.
Thanks!
Is there anything I can do at home myself to pinpoint the issue, or test your theory of the "bellows in one of the engine vacuum operated servomotors"
Just wondering....
Thanks!
Here's my situation: I have a 2003 Explorer. About 4 years ago, the AC wasnt blowing cold. I just kept adding freon every few months and it seemed to work fine. That last for a few years and now it doesnt blow cold at all. I had it diagnosed yesterday and they said it was the ac evaporator which needed to be replaced.
Because they have to remove the dash board, the labor is around $800, the evaporator $225.00, ac dryer $71.00, orifice tube $8.00, ac oil $10.00, ac recharge $ 80.00, plus the doors in the case are broken too. Total: $1200.00.
I am going to get a few more estimates, but here is my question: since the labor is a huge cost, is there anything else I should replace since my truck is 9 years old, as I do not want to have someone tell me next year that they have to replace something under the dash. I figure I should be proactive since they are ripping it apart anyway.
Thanks in advance.
