I am having an issue with my power windows. From the driver side and I can lower all of them no issue, raising them there seems to be a delay when I pull the level back up, however at each window individually they work no problem.

I am going to take all of the control pannels off today and look them over in each door to verify that there are no issues that are visible in that area. The fuse box is a little more complicated to me. There are a couple of fuses or relays I think that could possibly be the source of the issue. But before I spring for relays or motors I want to make sure I am looking in the right spot.

I am trying to determine if it's a relay problem that is starting to show for the driver side master window controls. If so I dont know which relay or fuse that would be since in the User Manuals there is not one clearly designated that I can tell.

Any assistance or ideas are appreciated.

How does each window react from its own respective switch? If they're all fine from each switch, but the problem remains when using the driver's window switch, I'd think the problem is isolated to the driver's window switch.

 

They all work fine from their own switches.

 

Then I would lean towards the issue being at the master window switch. What that tells me is it isn't a power flow issue, because each of those switches gets its power through the master window switch (the driver's switch) and if they all work fine, the relay is ok, the motors are ok, and all the associated wiring is ok.

I'd try a new master switch.

 

Alright will give that a shot. Gotta call the dealer see what that costs.
