I'm driving back to school last night and noticed that my windows started fogging up, but the defroster was still on. So I messed with the controls and it still would only push out a little air on no matter what option. I turned the speed dial and it didn't do anything? So would that be the blower motor? Just wanna make sure before I go diving in head first.

 

Check fuse first. Try tapping on motor, should be under hood on passenger firewall. This might get motor to run, if it does, motor is bad. There should be a resistor in the heater box by the motor, it could be bad.

 

Okay, I checked the fuse and it was fine so I went ahead and replaced the blower motor. It works now, but it wont shift off of defrost? At least I have defrost for now in the mornings, but do you have and ideas why it won't switch off defrost?

 

Vac leak. Defrost is the default.

Any idea on how to find where its at? Could it be from the cooling line not sealing all the way from the new blower?

 

Listen for hissing from behind HVAC switch in dash. This would indicate a leak.
Maybe just the vac harness plug is loose, or leaking from switch.
