Hey folks, im a smart fanatic & used car lot owner. I buy them every chance i get. BUT, this last 2009 cabriolet/brabus pkg i just purchased has stumped me completely. The top is not functioning when the switch is pressed, ONLY makes a clicking noise coming from the driver side, under the dash. i have checked all fuses/relays which seem to be fine. WHAT AM I MISSING?

I am pretty sure the motors for the top are behind the driver, only thing forward of the driver would be the latching mechanism at the top of the windshield, for latching the top in the closed position.
It may possibly be a relay under the dash, faulty maybe?

Thanks for your reply! any idea which specific relay/fuse may be for the top?

I would look for something to do with the motor for the top... but I have never researched it.
