Thanks RonD and EricB.
I ran the car for 2 weeks without the AC on, using just the fan.
So with the mode selector switch on the VENT position, 1 click counter clock wise.
Fuse 27 did not blew.
If i put the mode selector switch in any other position and thus activating the AC,
the fuse blows. And he does do that now basically immediately while previously after days or weeks.
And he does it with a hard pitch.
If i run the car without AC so just with the AC the same loud pitch sometimes occurs interruppting the sound of the radio
but without any fuse blowing.
So if I interpret the info you so generously provided correctly,
the short should be in the mode selector switch or in the cable GRY/YEL running from
that switch to the connector C2280B in the SJB and to the blend door actuator.
The actuator which I as advised have disconnected since to rule out that factor.
The other wire BLK/LT GRN could not be the problem as the VENT position is also connected to that
wire and i have no short when running just the fan without the AC.
I know how to measure resistance in the cable.
How to measure the model selector switch itself?
