Early 944 heater blower non-function

Heater dial - I'm guessing you are referring to the rotary knob. If the switch can't pass current the blower can't work so this is the first problem to eliminate. This is an electrical switch so the fact that is jammed is odd indeed. The control panel is removable so I would take that switch out for disassembly and lubrication or replacement as required. Image below found on ebay...looks like access to the switch is best achieved by removing the control panel. As a byproduct you get to lube up the rest of the mechanism :)

Hello everyone

My 1983 model 944 has a problem whereby my heater/air blower on the car dash is not functioning and the dial is also jammed on 3. Cannot move that dial to 2,1 or off.
Have checked and replaced relevant 16a fuse.

Would appreciate any comments on what to do next...

Thanks in advance.

Baz ??

 
Apologies about the post above...I pasted in an image and didn't use the preview button as all looked good but once posted it obviously isn't. I can't access the edit button to correct it.
