Heater
I have a 2003 F350 7.3L and my heater has stopped working. I checked the fuses they are all fine. I think it can be two possiblities the vaccuum booster is failing or the heater switch behind the glove box. Has anyone had any problems with either? or had their heater not work?
thanks

It just blows cold air. This is the second time its done it the first time it just started working again on its own. One thing i did before was i played with the vac lines on the vac pump and the pump vibrated with the key off and then the heater worked when i started the truck back up. I don't really count that as fixing the problem cause i really didn't do anything so i am hoping someone has had this issue and can help me out with what to do...

Works again this morning, didn't do anything but looked all the vac lines over and didn't see anything wrong. Anyone have some ideas?

I took the valve out of the heater line yesterday, seems to blow hotter. Not sure if this will fix it but i don't think it needs that thing in there anyway.
