Heater fan woes....
 

Hey guys, whattya think?

on my '85, when I turn the fan for the heater on, you can hear the blower going at full speed, but only a whisper of air to comes out of the vents... possible blockage? Do these things have finicky blend doors?

Dan

does it have push button controls or slide controls?

Mine is the same and I have the slider controls, and knobs for the heat and fan.

Are the blend doors on the RX7's controlled by Vacuum Acuators, Electric Acuators or are they Cable operated?

That would make a huge difference on diagnosis.

I have a ALL Data system and i could pull up some tests if you like. What year is it??

the car is an 85... dunno how they're actuated... I'd imagine electric...

Mine is an 84 GS if it makes a difference.

There were two versions of the control for the blend doors on these cars...

One had a Sliding knob for the Vent, Floor, Defrost selection... Those were obviously cable actuated.

The other version has push buttons. These are electrically actuated.
