Just did the same operation myself in recent days.
Gently pull out the ashtray and coin holder units until they are free, there is a small metal clip I think that needs to be depressed
Then unscrew the cup holder - there are 5 screws holding it in place
Then reach up through the available spaces and push in the tabs on either side of the Climate Control unit and it should pop out.
Disconnect the three (I think) cable looms to the unit
There are 4 (I think) screws holding the rear of the of the unit onto the front, remove the rear cover and you can see the screw in bulbs
Hope that helps
