A/C at your beck and call?

[[email protected]]

is a benefit of a luxury car having the A/C ready to go anytime the
Auto Climate conrol is on and is demanded? so it stays at a constant temperature?

And the fancy blower switch in the evaporator duct must cut it when it gets cold enough to start freezing up or why whould it be in there to begin with

if that is true then the blend door has cold air on one side and hot air on the other side. Blending to my desired temperature. As long as it is above 50
Farenheit Ambient temperature


I noticed that the blend door lever is replaceable. Do the metal hinges for the door rust , freeze up and the motor break a plastic pin off

Any one had to tackle the infamous blend door issue?

Like to know what you saw.

Im thinking that this time of year A/C is really not used that much here in Michigan. And it stays pretty cold in the evaporator duct. with blend door to full heat. Then it gets really cold outside and A/C doesnt come on til late spring except for the occasional winter running. Moisture sits in that duct
and rusts the hinges or suctions like fat to the bath tub and burns out motor
when it tries to open in spring.

Does that sound like it might happen that way?.

Thanks for any Input.

been thinking about changing my screen name to Johnny5 because i am always looking for Input. So my car no dissassemble. (from short curcuit)



Now that I have my A/C comp ground seperated from the PCM I might set up and on off switch so in fall when mornings are brisk i dont have the A/C
cycling on and off. Turn it back on in spring

Also if the A/C compressor is working alot PCM doesnt have to adjust because it is always cycling with climate control on. I might pick up a few more miles a tankfull also

I Never want to take the dash apart. Ever. It scares me. No one will
do it for me. Cant pay to have it done cause it's just some screws and clips.
i can take out screws. getting them back in is my problem

In the first place, you don't need the A/C on automatic. In the second place, the A/C is an important part of your windshield defrost system - it removes moisture from the air INside the vehicle. I wouldn't think of disableing it in the winter time, and I live in Idaho where it gets cold and snowy. The A/C is for much more than just cooling hot summertime air.

I agree with you on not wanting to take the dash apart to work on the A/C. I am a fat, old man on a fixed imcome and unable to do the work myself, have no one to do it for me and totally cannot have the dealership do it. If my heater quits in the winter time I will have to use my truck, which is much more expensive to operate, and if the A/C quits in the summer time I will have to use the 4/60.

I didnt disabble the A/C it disabled it self. Power Control Module cut off the ground to the compressor.

Appreciate the tip on defrosting.

How does the A/C help with defrosting on a balmy 20 degree day when the compressor wont come on at less than 50 degree ambient temperature.

Im sure the A/C would help on a hot day when they steam up but not in the dead of winter. Couldn't.

When it comes to 4/60 at least ya got that ...some only have 3/60
and when they get home a window that wont go up.

Good luck from one OFG to another

below 50 degrees ? easy answer. When the system is set to defrost
the above 50 deg rule is overriden. The compressor cycles enough
to de humidify the air then it is heated and sent to the windshield.
Just let the system do what it was engineered to do. Also most of the
stale captured water problems are caused by those folks who insist on
shutting off their ac completely a block from home and not turning them
on untill they have started down the block in the morning. By doing so
all of the air doors in the system are in the closed position and there
is now moisture or even water trapped in there. Also that stale water
just plain STINKS when you get that first blast when it is opened back up.
Engineers have designed delays such that it will not let the engine start
under a ac load. Just leave it alone and enjoy it. Dont try to out think
it. It will drive you crazy worrying. Phrawg

yes the part about not turning it off is right from the owner's manual.

Was the first thing I read. Didnt order the Blue Prints until Yesterday.

I do enjoy A/C very much even on mid seventy days I run it so i certainly dont want to jepordize that.

Ans now I know that:

If the wife has a hot flash in the dead of winter I can set Climate Control to Defrost 60 and not have to open the windows. Compressor will engage.50 degree rule does not apply. got it.

Thanks ,was wondering how I was going to run A/C compressor a couple times this winter without a garage

I wasnt second guessing the Engineers but just because they design something a certain way doent make it right.

im glad there are people here that are smart as them and willing to answer a question even if it doesnt make a lot of sense.

Thanks and Good Luck

we have a 1996 Lincoln Town car our air does not work. We took it to the
garage to get it checked, they said it was the Head Control. We went to the salvage yard and tried two of them. No air, so we thought we would have it checked again by another man . He said we needed a new compressor. We bought everything we needed for the air 320.00. He installed it and could not get compressor to stay on, so he said he could put a switch on it to work. my husband didn't want them to hot wire it . We took it to another garage they worked on it and when they got done they said we needed a head control. So again we went to a salvage yard and tried a head control and when we plugged it in something in the dash started clicking the man at there said it was the blend door and needed to be replaced. He said it is a long labor job six or more hours. the part only cost around 50.00. are there any instructions on how to take apart the dash to get to that part?

Hi and welcome to the forum!

I really hope it´s not too late, here are the instructions to replace the blend door actuator. Another way to know if that´s the culprit is when youre only getting either cool or hot air no matter what you select.

Be prepared as it´s a long tedious job to replace the BDA.
