Ok guys I need some help, my compressor is working but my truck is not blowing out air at all. I hear it working but no air is coming out of the vents or defroster. I thought it was my blend door but I checked it out and it was fine. Not sure if it is my control head or what. Any suggestions would be great!

 

Would help to know model and year of your truck. Have you check all fuses both in dash and under hood? Can you hear the fan motor running?

 

sorry 2007 ford ranger, yes the fan is running, everything is working it is just not blowing out.

 

I believe the system will default to the defrost/floor outlets if you lose vacuum. If the fan motor is working you should have some air flow through those outlets. Are you sure the fan motor is working and if so through all speeds?

 

everything is working, all speeds, the fan, all the actuators but the air is just not coming out anywhere

 

Only way that is possible is if the inlet duct is clogged, or the fan is really dirty/broken.

Pull the fan and check it.

 

Are the vent dampers closed?
