#68 of 84 2001 Ford F-150XLT heater doesn't work properly by obie100

Nov 08, 2010 (8:51 pm)

I have a 2001 F-150, once the heat gets up to the normal range I turn the heater control switch from off to vent/floor. After about 20 seconds I get warm air and then the airs cools down quickly. I can turn the controls off for a few minutes then back on and it works fine for another 30 seconds. I believe its blowing the heat through the vents from the engine heating up. I have noticed since having the truck that the radiator fluid levels are always the same & I have had this truck for 9 months now. I checked all the mini fuses and only one was blown, it was the fuse for my trailer hook up lights. Can someone please help me with this problem, I have two lil girls riding to school each morning wrapped in a electric blanket... Please and Thanks

#70 of 84 1996 F350 blend door by jgorski

Apr 19, 2011 (6:12 am)

I have the mechanical linkage control (two cables) the door works fine but it will not close all the way. I can push it closed with my hand but upon cycling the switch again it remains partially open. I have removed the control at the dash and at the blend door. I can see nothing wrong with it and see no way to adjust it.
Please help, it's to hot to drive this way.
Thanks.

I start truck, turn air conditioning on and it blows cold. When I accellerate it blows warm. The compressor lines are cold all the time. Is there a vacuum motor controlled flap?

Blend door could be broken at the hinge where it fits in the blend motor. That depends on year of your truck I suppose, though. Look up heatertreater.com.

#74 of 84 Can't control interior temp by alaskaford

Oct 30, 2011 (11:23 am)

I just bought a 2006 F-150 King Ranch. My problem is that I can't control the interior temp., in particular the heat. Since I live in Alaska the air conditioning isn't used. No matter if I use the auto or manual selector, no matter the temp. setting I use the interior temp. seems to have no upper limit - it just gets hotter and hotter. I can stop the heat by selecting an interior temp of 60 deg. which then cools the cab to an uncomfortable level. Any ideas on how to fix this? Is there an internal thermostat that I can replace?
Thanks -

#77 of 84 A/C Odor..FYI by wwest

Oct 11, 2012 (10:43 am)

[quote name= timestamp='1349462036' post='5070'] Not this odor. It's more like a ether smell [/quote]
 
For many years, more than 20, manufacturers have been experimenting with various methods for retarding or even eliminating the growth of the microbe colonies that result in the mould and mildew odor emanating for automotive A/C systems.
 
Some Lexus models currently incorporate a UV light source inside the A/C plenum. Another approach seems to be to lightly coat the evaporator cooling vanes with a fungicide. This latter seems to encounter 2 problems, the fungicide washes away within just a few weeks, or it is found that the fungicide chosen is adverse to human health.
 
It turned out that the evaporator in our new '92 LS400 was first coated with a thin porous nylon film and then dipped in the chosen fungicide to fill those pores. The problem came to be that once the fungicide (shortly) washed out of those pores the evaporator became a huge SPONGE for holding condensate until the exacting conditions arose for sudden, FULL, and virtually INSTANT evaporation.
 
BLAM!
 
The (cool/COLD) interior of the windshield suddenly fogs over to the point that all forward vision is lost. THEN you discover that Lexus relies SOLELY on the A/C for airflow dehumidification and interior windshield defogging in defrost/defog/demist mode...BUT...the A/C is automatically disabled (with NO indication to the driver of same) when the OAT declines to/below freezing.
 
Even were the A/C still enabled it's functionality for airflow dehumidification is significantly degraded as the OAT declines closer and closer to ~33F. Lexus at first admitted, full disclosure of this, but then subsequently discovered that no MSDS had been filed with the proper US agencies and began denying that a coating was/had been used.
 
Since ~'94 my LS400, and now my '01 RX300, and '01 Porsche C4 are all modified such that I can easily and indefinitely disable, FULLY disable, the A/C during the periods wherein it's only use would be for airflow dehumidification. The climate control in my '92 LS400 has an internal DIY electronic control modification that will automatically turn the HEAT to maximum the instant I switch into defrost/defog/demist mode, the blower speed rises to maximum accordingly. In my RX300 I always remember to quickly twist the temperature setpoint knob fully clockwise just prior to switching the system into defrost/defog/demist airflow routing mode. Luckily Porsche has not yet adopted the NipponDenso, Denso US, climate control design IDIOCY so it still automatically goes into HEATING mode whenever the windshield defogging function is activated.
 
During the period between purchasing the new '92 LS400 and coming up with the DIY modification, ~94, I alleviated the propensity for the sudden fogging of the windshield, and to a lesser extent the odor problem, via religiously lowering the windows slightly in the garage each and every night.
 
So, why is this important to you, an F150 owner...
 
ALL Asian models use, have always used, the horribly flawed NipponDenso climate control operation model, and with the establishment of Denso US (via merger/acquisition?) many US models are now subject to this problem.
 
 How to tell...??!!
 
Allow your automatic climate control to fully stabilize at your temperature setpoint comfort level. At this point many [most?] of "these" systems will automatically switch into cooling mode, face and upper body airflow routing. Once the system has stabilized then switch the system to defrost/defog/demist airflow routing, if you then do not get a significant level of HEATED airflow then your system is most likely modeled after the IDIOT Denso US design.
 
In about 2005 I stumbled across the fact that Lexus was secretly addressing the problems, my '01 RX300 had dealer set options that would allow me to turn off the A/C function indefinitely by simply turning it off manually one time. The system would then not activate the A/C compressor clutch, not even in defrost/defog/demist mode, until I switched it on, enabled it, again.
 
RX models newer than my '01 have additional dealer set options that could be used to prevent the automatic switch into cooling mode on the darkest, blackest COLD wintertime night. Plus 1 or 2 other options, differing actions with defrost/defog/demist mode with the OAT below 33F, for instance.
 
So here we are well into 2012 and it may well be that many other models, US especially, have adopted a few of these dealer set options in order to alleviate some of the IDIOCY of the NipponDenso, Denso US, design. Probably worth checking, DRILLING DOWN, with your factory rep about this matter.
 
Why drilling down..?
 
Even to this day Lexus does not allow dealers to willing/openly disclose the existence of these highly desirable A/C operational modification capabilities.
