(T) Climate Control

Looks like i have some problems starting with the climate control, the button which activates the compressor isnt activating it all the time, Happened first thing this afternoon when i tried it, turned off ignition then restarted car and pressed the button again then it worked.
Parked up a little while ago having been for a drive, thought i would try it again, nothing at all now, passenger side door electric window played up a few times in the past week or two as well, went to close window,got to the top and wound itself down,tried again and the same thing.
Checked the manual and done what it said about keeping the window button down for 5 seconds and it worked.
Been ok until yesterday and same thing happening again,done the same thing and cured it touch wood, now i am wondering if there is an electrical fault connected with these things starting to happen, unless of course the airconditioning compressor has packed up.
Oh well back to Fiat tomorrow.

make them look for a too much voltage falling when engage the starter. The current intensity shouldn't be more then 180 amper. If more, the body computer looses some setings.

Many thanks for that, i will ask them about that, that might explain the memory setting on the electric windows, i will contact fiat first thing tomorrow.
