Problems with EATC

I live in Europe. I've got a problem with the electronic automatic climate control. The problem is the bigger as you can't find any good service that could help me. You know there are not meny US cars here.
Back to my qeustion. The problem is that the EATC holds the inside temperature too high. Also when the outside temp. is high and so inside the EATC firstly bigins to cool it down but after when it should maintain the set temperature it begins to blow out of the upper blover hot (not warm) really hot air, then after a while it turns back to cooling. When I want instant cooling only in the max a/c mode. When it worked correct it blowed hot air only to feet. Have anybody any idea how to restore the EATC?

Just a thought for you.....My wife once put a towel over the dash just before our "Dashmat" and our climate control went haywire. What happened was that she covered up the tempature sensor to the climate control. The sensor for the climate control should be between the radio and the passenger airbag on the dash. Its a little vent about the size of a quarter. If that is blocked the climate control will not work properly.

Greengoose is correct. There is a sensor in the dash that measures the temperature of the air inside for the climate control. I had a grand Marquis with that system and had to replace the darn thing twice. I just dont know where it is located in an Exploder though, but my best description wou be to look for something that looks like an airhorn with a tube attached to it and a thin wire inside of the horn. Mine was mechanical so it had a lever on it that was attached to the wire. The newer ones may be electrical.

Thanks for your replys. I think either that it is the climate control sensor but I don't know the part number and I'm afraid that anyone here who never did such a work should open the whole dashboard to replace the sensor. I found it and tried to cleanse it but it didn't help me. One more time thanks for your replys.

Just an idea. Set the climate for 70F then take a hair dryer and blow hot air on the sensor and see if the AC kicks on.

The sensor works some how. But it changes the airflow only between hot and cold. It seems to me that it changes the temperature only when it is too hot or too could and it don't maintein the set temp.

Hi
I'm living here in Europe too and i posted the same question this month (without any answer yet).
(Dead Link Removed)

my 95' X Eddie Bauer has exact the same problem. i found a pneumatic valve under the hook, which controlles the heating. it switches only on or off. maybe this thing must have continous moving ?

i#ve read in other posts, that there must be an "regulator" under the dash, who mixes hot and cold air, but i have found no such thing.

Have you solved your problem until yet?

No, I didn't solve the problem jet, and I'm still looking for someone who have an idea about it. I thouht that if somebody near me would repair US cars and had an computer on which I could connect my car that an answer would come out, but every person I tried here in Slowak republic, in Austria don't have the right equipment.

Blend door

I've found the following post



Now i have following question:
is our "problem" normal, can the X auto clim.contr. blow hot and cold air, or is the blend door for "regulate" a mixed temperature.
How can i test or repair the blending door ?

thanks for all helps
