i can't use auto because at 90 degrees it keeps the fan on high.
if I leave it at 90 on manual and adjust fan speed to comfortable level the heat works fine, equal temp on both sides.
i had the control rebuilt because the digital display failed, the control still functioned but you couldn't see what it was doing.
it is reading the outside temp properly and does not flash for any errors.
all of the zones work when selected and setting fan speed manually does function properly.
the passenger door controls function as they should when they are activated.
have the same problem?
