When I try to increase the cabin temperature, no change is made.
It will not work on auto or manual. When I press the defrost button, it shows that it's on but no air comes out of the vents at the bottom of the windshield.
Rear defrost does the same, the heated mirrors light comes on as well.
Fan controls work.

Anyone have any thoughts?
Thanks

Have you checked the fuses

sorry for the late reply.
I checked all the fuses under neath the dash.
All are good.
Do you think that it's the control panel? All the lights have burnt out of it.
all the buttons still function though.
