Is tha fan controlled by the ECM on the 84 at all or it is just the fan switch that controls it?

There is no ECM involvement on the fan operation on the '84. The temp switch in the right head and the pressure switch on the A/C compressor are the only controls.

RACE ON!!!

Only the 1984, but since so much of the '84 carries over, I get a royalty on all the C4 manuals.

RACE ON!!!
