Leckie Windows not working

[B4Bishop]

Hi,

Got a B4 with only the drivers window working on the swtich, all other 3 windows will not work when using swiches. But will go up and down when using the drivers door key in the lock.

Is it really as simple as new switches and all will be good, or does the drivers side window motor control the other windows somehow?

Could i easily enough just test the switch by bridging it?

cheers
