Land Rover Repair: rear windows, inhibitor switch, volt supply

Question
I have a 96 disco and the rear windows do not operate.I have checked the fuse and cleaned  the lock out switch in the middle console and did not help.should i jump the plug going to that switch to completely rule it out?or is that not a good idea?what else should i check?

thank you

Answer
The two rear switch are energised by the White-pink coloured wires. Check the 12 volt supply at those switches' cables.
The 12 volts supply provided by the window lift control unit's 4th pin (white-pink).
If it is allright, than check the ground at the gray-green coloured cables. If there isn't ground than the rear window inhibitor switch faulty, or that's ground wrong.

Good luck...
