But seeing as the switch isn't lighting up it may indicate a power fault. Either at the climate control unit itself or somewhere along the circuit - before the climate control unit.

You can check power and earthing at the plug connection at the a/c compressor plug. If there is no power there, work your way back (checking power) along the wiring loom. Check at the relay/fuses. If everything else is in order, you may be up for a climate control unit.
hmmm thanks for the suggestion. I recently checked with the mechanic, i think it was yesterday and he said everything seems fine. Just the switch doesnt work. WOuld there be any places i can get the climate unit?
