Hi, folks,

Need your inputs desperately. All four windows on my regal quit working at the same time. But the power door lock works fine.
I have checked the fuse and I am sure it is fine since my sunroof still works which is using the same fuse as power windows.
I am going to check the relays this evening.
Someone also suggest that I should look at power window switch on the driver side. My question is, will a bad window switch also disrupt power door lock?
Anything else I should look at?

Thanks.

Check your ground bus. I believe it'* in the floor next to the front seats.

Hiya fellow Regal owner. Check your drivers door main switches. I noticed there is a switch issue in these cars because each and every one from the JY is gone. Experiencing a little myself with power mirrors etc on mine, this seems to be a common area.

I'm working to check the switches, the wiring where it goes through the door boot and then to the doors themselves.
