2008 Ford F-350 Super Duty Q&A

2008 Ford F-350 Super Duty Question: I have dual heating heat only on the drivers side and cold air on passenger side

What could cause this and how would I fix this problem ? -
Answer 1
We can offer a guess but this really needs to be tested by a qualified mechanic with the proper scanner. It is possible the heater blend door or it's actuator is having a problem but that is a guess. Scan test should show where the trouble is or at least the right direction to take. -
