2010 W212 Power Boot Closure

[JimC007]

Hello all, I have searched everywhere for a solution to this problem but recon you guys will point me in the right direction. My E350 CDI has Power boot Closure with switch in drivers door and the usual red illuminated switch in the boot lid. The boot opens manually or with the fob button or the door button but will not power close. It did operate but has stopped working at some stage. I have had the battery renewed and am not sure if this could be an issue. I have checked the 20 amp fuse in the boot and its ok. The illuminated switch in the boot lid appears to be getting power but wont operate the lid. Is there a relay for the motor and if so where is it. Wiring diagrams I can find are not detailed with this. I would appreciate your help if anyone has any ideas. Cheers!
