VT stalling and misses when air con on

[HSVVP]

Hi I am totally lost for ideas on this problem.

I have recently bought an S pack vt and up till now have been very happy with it.

This problem started the other day when it suddenly lost all electrical power while I was driving. I put the clutch in and stopped it from stalling.

Since then it has got more frequent, the car misses at high revs, stalls/loses electrical power at any rpm, but only when the air con is on.....

When the air con is switched off, the car runs perfectly.

I have checked the fault codes and nothing comes up (just flashes 12 over and over).

I've looked everywhere for ideas as to what this could be and I cant find anything. Any help would be appreciated.

Thanks Jack.

aircond clutch is buggered. it allows the pulley to slip when you need the power to keep the engine running
