Engine cut out when a/c switched on/off

[bertman]

Blooming a/c is driving me nuts
When a/c button pushed in or out sometimes it completely kills the engine.
there is no blip when switched on.
Had engineer come out to look,gas in system,checked hp switch etc.
Discovered there is no power going to compresser,ran an inderpendent feed to it and clutch functioning normally.
Waiting to vagcom at weekend to see if anything else is up.
Worked fine before,car not used for a few days and then probs arose
What else should I check?

Are you 100% sure the A/C compressor is not seized? I had a Jetta that my wife drove that kept calving alternator belts until we finally realised that the A/C compressor had seized. When the defroster system called for the A/C, it would almost stall the engine while the belts screamed like a banshee.

All I am saying is check the compressor to see if spins freely.

The original question seems to mirror the symptoms on my 1994 aby avant.
It was fine for ages after buying the car, then after a period of dissuse won't work.
Anyone any suggestions on this one.
There is deffinetely no belt slip / schreeching taking place.

Checked movement on the compresser and it turned by hand,no sreeming of belts or anything
