I recently replaced the power window switch block on the drivers door with
one from a salvage yard, becuase I was unable to lower the drivers window.
After doing so the window worked great. The only problem was that none of
the other windows could be operated from the switch on their respective
doors, only from the switch on the drivers door. Thinking that the switch
block that I installed perhaps had a short on the 'lock switch', I acquired
another one and replaced it again. I am still having the same problem.
Any suggestions on what to check next?
