I bought a new driver's side switch with lockout and replaced the old switch, but the windows still don't operate (front and back) Here's what I've done to test it:
1. Plug the driver's plug into the passenger's side switch - the window works.
2. Plug the passenger's side plug into the new driver's side switch - it doesn't work.
I'm almost certain the new swich is good. Is there something I'm missing?
Thanks in advance for your help,
