Air conditioning fan switch

[Dan Williams]

Is there a source for the fan switch? Either the  oem reostat resistor type fan switch or the current 3 speed switch would be ok.

Trying to convert my 63 switches to these newer switches and all the wiring is gone from the car so I a recreating this from scratch.  Do you know which terminal on each switch goes to which wire?  I believe for the fan switch the B terminal is Power In (from the battery), the M terminal is Power Out (to the fan motor) and the O terminal is ground.  The temperature switch terminals are labeled O and L.  I believe one of these goes to the compressor and the other goes to the fan switch but I don't know which is which.  

Thanks,

Tom

I received part no.3004c but it does not have a shaft on it to put the knob so the coolant flow can be adjusted.  What is the correct part no.

Oreilly Auto Parts sells the 3 speed Murray switch which works like a champ.

Sorry abt that..  I guess that's why they don't show the front..

That's okay I got a fan switch that works great from O'Reilly and it seems as though The air conditioner now works great so maybe it was just the fan switch that was a problem. But I did receive a link previously in this discussion of the correct switch to get for the temperature gauge if I need it
