Hi,

This is odd because the driver's side windows work together and the passenger side work together. The power for the right rear is from the right front switch. The front works and the rear doesn't on that side. The same thing with the left side (driver's side). Note both the left and right sides door modules power from the same source.

Did both fail at the same time?

Do me a favor. I attached a pic below showing the two window circuits. I noticed three of the 4 grounds are at the same place, but at this point, that is the only thing making sense to me as far as the problem.

At the driver's switch on the driver's front and passenger's rear will be a black wire that is ground. Check to see if that has continuity to ground.

Let me know.
