2006 Ford F150
The AC on my truck is not working and blows HOT air. Back in the winter, the
heat was not working but I took it to a local repair shop and they manually
shifted the blend door actuator to allow warm air to blow. This summer it
became hot and they tried to manually switch it back to allow cold air, but we
are getting no cold air. Please advise as to what might be the issue. Thank
you!
