Removing the 30A relay stops the fan. Removing the 15A relay does not affect the fan. I have not located where to unplug the A/C push button control. Can you help me locate it?

Removing 30A fuse means the auxiliary fans are working at high speed and the circuit should be controlled by the A/C compressor pressure switch. Test the Brown/Blue wire from relay to A/C pressure switch for shorting to ground. Unplug both relay and pressure switch to test.

Here are a description of the Push Button and auxiliary fans.
