Is it extremely cold in your area? Does the vehicle reach operating temp? Are the heater hoses hot?

Yes its cold! And yes my hoses are getting hot and cold air is coming out of the vents. So far everything is registering good just no heat from vents all cold air. Have 2 mechanics scratching their heads they dont know.

Usually there are doors that open and close, depending on whether your using ac or heater. Maybe one of those isn't letting air go across the heater core, only.

The last mechanic thought it was the doors also but apparently it checked out fine 2 mechanics looked at my car and did the same exact things to my car and found nothing someone told me it may be a relay swith. But one of the mechanics said it wouldnt have anything to do with the heat. Also asked him if it could be a fuse ihave bad fuses he said no.

If the blower motor works ok, I don't think it is a fuse.

There is a temp control cable that goes to an actuator, that's where I'd start looking. The database I was looking at doesn't show enough about that actuator?
