Front Air not working.... rear is working —-help please

[ClintR2]

I have a 1998 LC. The Front Air is not working.
No heat and no ac come out of the vents. However the defroster is working.
The rear air works.
Just the front AC and Heat do not come out of the vents.

I can hear some noises and sounds when it is going from auto to fan speed and alsonfrom AC amen heat.

Thinking it might be the front Blower.

Any ideas on what it might be?

Have you tried putting it in diagnostic mode and checking for codes?

 

[ClintR2]

Yes, no codes are coming up except 13– knock sensor.

If you have air blowing out of the defrost vents it is not the blower. Will the defrost vents blow harder when fan speed is turned up?

 

[ClintR2]

Yes, the deforested will blow dofferent speeds.

Sounds like the outlet servometer
