Now, the switch is connected to a Bosch relay (12V 20/30A # 0 332 209 150- http://www.tessco.com/products/displayProductInfo.do?sku=66032&eventGroup=4&event Page=1). Everytime I turn the switch on that small relay (small black box) goes crazy with a funny sound coming out of it ???? and of course the roof lights do not work ??
Any idea what it could be - replacing that $ 3 box does not work - I did that already 
Many thanks for helping out.

BTW: I live in Costa Rica so going back to the dealer is not the first option I want to hear  |
relay is right under the dash under the steering wheel? that's where they normally put them.
I'm guessing it's wired incorrectly.
look at page 14 of this wiring diagram pdf from Bosch to see how it should be wired correctly.
