Before I start ripping everything to bit's Can anyone point me in the right direction first.
The car's a T plate Disco 2 TD5 with electronic climate control rather than the standard rotary heating controls.
Everything was working ok until yesterday when the car felt cold so I turned the temperature up and it didn't get any warmer on either side of the car.
The water level in the expansion tank is ok, and it hadn't been using any. I bled it and back fed the system through the top bleeder hole just to make sure it hadn't developed an air lock, but no change.
The temperature guage sits where it should in the middle and I ran from Stirling to Dunfermline and back to Larbert without any sign of over heating, but the inside of the car was absolutely freezing. At one point I got some lukewarm air through but not enough to make the car comfortable. I can also reduce the temperature down to freezing and get it back up to lukewarm.
The air con's never worked (that Ive noticed).
Any pointers in the right direction would be appreciated before I start going down the wrong direction and replacing sensors etc.
As yet I haven't had time to do the manual diagnostic as detailed in the Workshop manual
