I've got a 2003 Mondeo . For those that don't know it has a comprehensive electronically controlled climate control.
It's stuck on and none of the controls will work.
It comes on when you turn the key and I can't turn it off or change any of the settings. I'm stuck with the setting the last time that I used it..
Any ideas anyone?

No but I'll take the opportunity to whinge about the relay Ford have specified to control the cooling/aircon fan on our Fiesta. Basically it ain't man enough for the job and has now twice welded closed.
This has the effect of potentially flattening the battery. On the last occasion, after a mobile phone talk through, my wife fixed it by bashing the relay with a metal sweet tin she found in the glove box!
You first need to know whether the problem is electronic (the climate control end) or electromechanical (the heater control valve). The valve is well-known to fail on the Fiesta and the Mondeo may well use the same part.
The control system sends variable-width pulses to the valve so you can't just measure the DC voltage going to the valve. Fortunately the valve is quite cheap (£25 or so) and relatively easy to replace - on the Fiesta anyway.
Could the control panel have got unplugged?
Don't think so.
The integral display and "on" LEDs still work (FSVO work)

My Volvo V50 did this when the cable harness in the passenger door connecting to the temperature sensor in the door mirror broke. Then the climate control did not know what was going on so became wildly erratic - stuck on heat for quite sometime.
Adopt the system used on my Land Rover. To turn the heat on or off I open the bonnet and turn the tap that controls the hot water flowing rom the engine cooling system to the heater!

stuck relay or bust electronics. Ouch.
I think the fact none of the settings can be changed (rather than the system not responding correctly to settings) if fairly obvious clue.

Sounds like you need to upgrade it to one that works, or a lower current fan. Brian
I had one of those. Used to turn it on and off while stopped at traffic lights. Got a few strange looks - especially from unwitting passengers.
I took the OP to mean that moving the controls didn't affect the heat output, not that the readouts or whatever didn't change on the console.
You had passengers who didn't know they were passengers?
Well, some of them soon wished they weren't. Especially the ones in the open back when I went over the St Stephens level crossing rather fast.
I've read this about three times, and I still don't get it. There's a family fault in my car where the electric windows die because of a mangled harness into the door. But why on earth does the climate control need to know anything about the temperature of the door mirror?
I used to have a car with climate control, and AFAIK it was the temperature of the _cabin_ that mattered...

clever ones sense outside air temps too.
when its very cold outside inside air is drier and you need to add a couople of degrees..
it is measuring the outside temperature - I think. Certainly that it what the Volvo main dealer repaired - under warranty.
It's a "comprehensive electronically controlled" climate control.

a somewhat obvious comment methinks
The fan works (as I think, does the heating element)
What doesn't work is I can't turn them off.
There's no "controls" to move.
There are buttons to push, and pushing them does nothing. (In as far as I can tell ATM).
I'm stuck with moderately warm air coming out of the top and middle vents, which of course means that I have freezing cold air coming out of the front and top vents until the engine warms up.
