I have a 2007 Jaguar Xj 8. My front master switch will let the right rear window up but, will not let it down. I have to go to the right rear window switch to let it down. I can hear a click when I attempt to let it down from the master switch. The back switch works just fine. Can someone tell me how to fix this problem?

 

Quickest way probably is to replace the whole master switch with a used one IMO.
