The A/C (and heater) fan on my Disco has been acting up for some months now. Often will just shut off for a few seconds, then reactivate.
The fan control slide switch finally became non functioning...fan would not come on, hence the A/C will not come on.
I replaced the dash mounted switch, (complete unit with rotary controls etc, $200.!!)
Still no fan action.
Where should I look next?
Thank you
