so this is the situation and it's driving me mad

Discovery 4, 2013
NS Rear window not working (not working from master switch too OSF) All other windows function
replaced NSR Switch - not working
replaced NSR module - worked for 5 minutes
replaced OSF Master switch - no difference
replaced OSF module - no difference
removed & reconnected NSR module - works for 5 minutes again, and continues to work for 5 minutes every time you remove & refit module
All other windows work fine

 

As with seat controls, do you need SDD to reset the module?

 

You shouldn't do because it's a module not a control unit
