try the a/c control unit first.

When you say fan control unit are you referring to the fan/blower motor switch on the dash that you use to turn the blower on HI, MED or LOW?

It's kind of weird that the fans and the a/c control united stop working at the same time and when the a/c control panel start working again the fan a work to

the a/c control unit also controls the fans when the a/c is on. if the control unit doesn't work the fans can't either (in most cases, unless threr's a short).

that is why I suggested replacing the control unit.
