Reading an old thread, trying to learn about my klima. Why does the kickdown switch cause the klima to open and thus the compressor clutch to disengage? What's the relationship betwen kickdown and the compressor?
Is it that the AC would sap power from the acceleration that you want at that moment?

It takes signals from the following:
1) Signal from the CCU going through the Evap. temp switch and the low pressure cutout switch. This signal tells the Klima to close.
2) Signal from the kickdown switch. This signal tells the Klima to open.
3) Signal from a temperature switch. This signal tells the Klima to open if the temperature it above the setpoint.
4) Signal from the tach. I can't figure what the Klima does with this on the '85.
So, if the signal is present from the CCU and there is no kickdown signal and no overtemp signal, the Klima should close the relay and the clutch should engage.
