Title: ACC Hot n Cold :)
Post by Xeen on Oct 1^st, 2009, 3:35pm

My acc is unstable.. it heatens the car fast,but after a while it gets colder and colder... and after approx 15min it gets warm again.
It does this all the time in cycles. must set the temp to 27 C to have a ok temperature in the car..

The heater matrix is new and the enginetemp is stable.(new tempsensor and termostat.)

Can it be one of the tempsensors in the acc system? how do i check? have done the acc procedures reset osv..

Cannot help you I am afraid but I have the same problem for some while now, changed various parts without success I am advised that the problem is most likely to do with the SATC Module , even this I have changed albeit second hand also de icer switch, Pressure switch , Regas and compressor, if you should happen to get it solved let me know what the solution was mine will not even reset and I am very reluctant to go down the path of professionals, can be very costly, good luck.

Have you had your A/C serviced recently ?
May just need the gas topping up ???

my problem has nothing to do with the A/C.. have same problem with AC off.
Its the heat-flaps inside the heaterbox that is beeing wrongly adjusted by the ACC.. i wonder why.
No faults in acc memory either...

Do you have enough cooling fluid?

Have you read this page.....http://www.fordscorpio.co.uk/aircon.htm :)

Climate control in the Scorp isn't like a conventional vehicle heater. It does blow hot & cold to try & maintain the temperature set on the display panel.

If it is obviously not working correctly & you've tried a different SATC etc, then it may a sensor problem.
If there are any problems with sensors then it should show up when doing a reset....http://www.fordscorpio.co.uk/ccreset.htm

Hope this helps :)
