heating system odd fault

[Piggy]

Had a squeaky fan for a while so was prepared for failure...just hoping it would hold till I removed dash for flocking and ripped out the AC properly.

Well it seemed to die the other day, unless you went over a bump and it would come back to life. Then it died completely.

Next day I realised that the A/C button/light and air recirc button/light didnt work and had no effect and neither did the heat control. No flaps movement.

Checked fuses, nothing blown.

So got a fan off Ozone. Fitted today and no difference.

I know fan works, thats been tested.

Any ideas??
