Sounds like you external temp sensor has gone, it's located in the passenger mirror, do a search on here, it's quite common.

Oh and welcome to SCN.

would that effect the iside heating system of the car i thought that sensor was only to tell you the outside temp

yeh it does - mine was temporarily cut off as it was stopping the aircon from working! Seat will try and charge you silly money for the sensor IIRC, Maplins do the same thing for a couple of quid.

where is this sensor located and how doi remove it

 

[pdcupra]

just underneath the passenger side mirror, it looks like a black plastic nipple.

but it is your sensor by the sounds of things

 

[delboy21]

have heard there is an internal temp sensor would this not control the heating

Someone smashed my wing mirror causing the care to report -30 outside temperature.

So - the aircon wouldn't come on. This was easily solved by disconnecting the temperature sensor but you have to remove the passenger side door card to do this.

I just bought a new mirror including sensor for £77 from www.wingmirrorman.co.uk - seems like the original part too! Easy enough to fit and my aircon now comes on okay.

I think my internal sensor might be a bit iffy though - so that's the next job!
