Hi my heater unit has gone on the blink the heater fan works the position of where the air comes out works but that's it is there anything that can be repaired or is it a new unit thanks

I don't understand your post mate as you've little punctuation, no commas or full stops. I got the first few words but what do you mean by 'the heater fan works the position of where the air comes out works'?
The Scudo heaters do give problems but usually stop working altogether but if you can be a bit more specific, you may not have to replace it.

Hi sorry my 06 standard diesel,has aircon via a switch on the dash.the fan itself works perfect , and the slider switch to decide where you want the air to come out from works perfect , the problem happens when it comes to setting the temperature , the sliding switch doesn't seem to work and only gives a medium temp in the cabin. I have taken the facia front off the dash and it seems to be an electronic unit not the manual type ,is there any serviceable parts in it or would it be a new control unit .thanks in advance

If air not coming out cold Suggest having the refrigerant gas/liquid checked and perhaps topped up, especially if you are uncertain when it was last done. There are cheap and cheerful DIY kits...I always paid a bit extra at a garage to have all the old liquid sucked out before new was pumped in.

Thanks for the reply, I don't think it's the referegents side , it's like something is wrong with the control mechanism that it won't adjust the temperature
