1973 FJ55 with Denso A/C Fan Switch Question (1 Viewer)

[GLSisk]

We are working on an FJ55 w/what looks to be factory air.

The fan and compressor controller switch is a wheel, not a knob and doesn't work. By passing it makes everything work fine.

First, anyone have experience with this? My '79 FJ55 had factory A/C but I don't remember what the switch looked like.

All comments/suggestions are welcome, except any regarding what kind of dog to get. I like Chesapeake Bay Retrievers, haha.

Thanks,

GS

That looks like it could be a potentiometer that works with an ac amplifier circuit located near the evaporator. When you bypassed the control, what exactly did you do?

That plug on the end looks like it might fit the ac amplifier

Looks like the a/c in my 77 FJ55.

The only fan switch is on the dash, 3 speeds.

The dial in the a/c unit is for setting the a/c from lest to very cold.

It also turns the condenser on.

Not sure if this helps much.
