This is the second instance of the Air Conditioning fault in about a month - same symptoms. The light on the switch comes on but no cool air, no click from the electric clutch, no change in engine speed to compensate for the AC Compressor loading up.
Booked in to Lookers Macclesfield again for another go - they got it working again last time and attributed it to the setting up of a replacement UCH Module about 6 weeks previous - i was suspicious that this was not the case as the AC worked for a while after the UCH Module was changed.
Checked on the forum and it sounds like there is a problem with the AC System pressure sensor and this would inhibit the operation.
At first i found a section in the handbook which says the AC is disabled when the outside air temperature is 'low' (don't know if this is 5 degrees C or 15 degrees C or what!). Anyway, the air temp today is about 8 degrees C in Buxton - bit chilly but would have thought it should operate at this anyway.
I explained to the nice lady at Lookers that i had looked on the 'net and was trying to be helpful in doing so but got the impression that they were not going to take this source of information seriously as it is run by Renault people.
As i said, booked in tomorrow hopefully they will resolve and not sting me for regassing etc that may help them recoup some of there costs.
I'll let you know how i go on.
Great forum anyway and lots of good info! Thanks
