i have a 1999 range rover 4.6 how do i turn the heater or a/c completely off. i can't tell if its off there is no indication. i would think it should say off but it doesnt there's always a temp reading on the display.

 

I have the same problem I can't figure out how to turn the HVAC competely off????

 

turn the fan down to one, then hit the ac off switch, then turn the fan down one more time
