I presume this a 2.3 Petrol. Mk1 Galaxy? If so, if I recall correctly the CC ECU is down to the left of the centre console, near the passenger footwell. These units are designed fail-safe so any hint of a problem and they will default to off (in my experience). I once had an intermittent problem on a W124Merc, solved by removing all the conformal coating on the ECU circuitboard (with Nitromors!) and re-soldering every joint. To my amazement it worked. hi mashbury,thank you for your reply...no its the 2.8 v6 4x4,your info is a great help,the cc failing on the galaxy seems to be quite a common thing,your method of resoldering the circuit board is what i would do..i intend to get to the bottom of this cc not working.. :) so thank you again..all the best..den.
