Evening all. Having purchased my terracan a month ago, I’ve managed to sort most of the problems but am stuck scratching my head at the last one! I’ve changed the actuator which controls the heat from hot to cold and vice versa but it still doesn’t work. I have self tested the heater module as per the instructions previously listed on here and it come up with 20. The motor works and drives when connected straight to a battery so I’m guessing it’s what sends the signal for the change which is at fault?
