Had an EAS FAILURE on the way home.
Turned out to be COMPRESSOR FAILURE.
On reaching home I turned off the ignition and heard a hissing as the car visibly sagged.
The compressor dues actually run, but the system won't repressurise with a short open.
I'll leak check with washing up liquid in daylight but that hiss and sag has me thinking a valve is stuck open...
Need the car tomorrow night (Monday).
Accelerated diagnostic steps would be much appreciated.
