If none of them work then maybe the appropriate fuse or relay has failed. Try that first and report back.

You dont tell us the year / variant of your vehicle , nor where you are located. This info can be useful.

Neil,  other than guiding you to check the fuses/relay I really cant help. I havent and dont own a Lacetti and unfortunately my stored database doesnt include this model so I cant look up wiring diagrams or any other data.  Best I can offer is that you read through your Handbook for fuse locations applicable. 
If you dont have an owners manual they are available on the internet. 
Possibly a knowledgeable Lacetti owner may read your post and offer some solution.

If you put your vehicle details in your footer (like mine below) they will automatically appear under your future posts to assist readers.

Neilo,
 Like Ed, I don't have experience with the Lacetti. However, his advice is sound, check all the fuses first.
 I cannot help but notice that the Lacetti has a row of knobs (heat level, air direction, fan) and switches (A/C, recirc, HRS) that are suspiciously similar to the Aveo. In fact it looks as though this bank of controls was lifted directly from an LHD Aveo, and dropped in the RHD Lacetti.
 What's the relevance of this?
Well, these switches do have a reputation for being a bit crap. One of my  posts actually asks for help with mis-functioning A/C . After reading how poor these switches are, I disconnected them, wiggled the connectors, and function was restored. Same goes for the light bulbs that live in this area.
 If the Lacetti was my car, I would:

(1) Watch this video, it deals with the panel removal (ignore the radio stuff).



(Take pictures of how the knob cables are connected and then disconnect them).
(2) Get the panel out of the car and spray all the connectors and switches with contact cleaner.
(3) Remove the light bulbs and test them.
(4) Use a multimeter to test the function of the actual switches.
(5) Reconnect and wiggle at the same time. Turn car on and wiggle more.
(6) Remember that the A/C and the light, will not function unless the fan is at 1 or above.

Good luck, and please put the spec in the footer. I have no idea if you have the version I have described, or the one with the digital temperature display.

Good constructive contribution Metro1000.    Hopefully there may be a solution from this.

Neil, Generally between various members 'heads' we try and resolve as many posts as we can.
The sad thing is a huge number of forum members dont post the outcome (we simply dont hear from them again) so we never know for sure if our solutions worked.  We have to assume possibly they did otherwise we would have had more 'no that didnt work' posts.
We would like you to post the outcome - good or bad, for our learning curve.

Just a tip: if you enter your vehicle details in your 'footer' (like mine below) on your future posts your vehicle will always be identifiable to Forum readers which assists in the replies.

Hi a sort of update we got the car today so had a go at the switch problem,all the fuses and relays work,strangely the A/C switch lights up before you start the car (with the fan in position 1) when you start the car the light goes really dim as if it's not on ,the other 2 switches are not working (illuminating) the heated rear screen does not click in and hold,trying to get the panal off is a real game got it so far and then stopped due fear off snapping,looked at more you tube videos so I will have another go now I have more ideas.

As in the last post on this subject I found that mine worked when I held the wiring plug over to one side, showing that there must've been an internal break somewhere in the switch unit. I used a small nylon cable zip tie to permanently hold the plug over to the 'working' side, sorted!
