Windows Not Working

[Stewie2k7]

2006 Polo 9n3 1.2 3cyl

My Windows Have Been Working Intermediately The Last 8 Months and Fully The Last 3

I've Gone Through Many Similar Topics and Tried Their Solutions But To No Avail

• I've Changed The Window Switch
  I've Soldered New Capacitor And Relay To Window Reg MOBO
  I've Changed The Window Motor
  I've Cleaned, Repaired and Repined Both Female and Male Connectors for A-Pillar to Door Loom Connectors

The Strange Thing Is if i Disconnect and Reconnect The Battery, The Window Will Work For 5 Minutes Before It seems absolutely dead (No sound of the motor or response)

Is the something to do with the ECU or a Control Module that I'm not aware of ? do i need to plug it into a pc or something?

I'm Really at my wits end and any help would be greatly appreciated

Many Thanks

Stewie
