i think they use it to move flaps

Finally had time to have a look at the problem and found out it was a electric vacuum valve on the firewall that controls the engine throttle control when the Aircon compressor engages the engine revs up. So it was the electric valve on the firewall squeeling, need a new one I think might burrow one to see if it stops it.
