Removal of glove box and ECU for aircon

I am trying to replace the ECU for the aircon hot/cold mixer it is attached to the left hand side of the centre console,I have taken the side panel off but need to remove the glove box to get access to the top part of the ECU retaining bracket,(the glove box has 4 bolts at the front and a single screw attachment at the rear underneath that I have removed) but it does not move,are there more fixings I have missed ,I do not want to break anything or set the airbag off
