On my 2000 XKR convertible there are four vent holes under the rear window. I have not been able to find any information about them anywhere. It's like they don't exist. Can't get a good look at them without removing the fuel tank. Only thing I can think of would be for heat or a defroster. I don't see any way for them to be connected to the HVAC and there is an electric defroster grid on the glass. Does anyone know all the what's and how's of these 4 holes?

 

Well I answered my question. Those holes are just holes. They come out above the fuel tank.
