Recently both front windows have failed to work intermittently. The last time was a cold snowy day and my first thought was that they were frozen but I don't believe that to be the case. There was no noise or movement or any indication of any current draw.
They are fused separately so I have ruled that out...any ideas. It's too much of a coincidence for two swithes to be bad at the same time. When they fail, they fail together and when they work, they work together.
Thanks in advance......

What year car?? In 1990 & later the windows are controlled by ECU.

It's an '89.

Did you spill any drinks/food near your center console? That would be my first guess. Clean the switches with contact cleaner and see what happens. Good luck!

The only other thing that all windows share is power supply(relay) & the ground. Relay powers both fuses!! Do any of the windows work? Relays are under plactic cover behind fuses. Pwr. window relay has the "letter" F beneath it. Most of the relays there are the same.

The rear windows work fine when the front windows fail which would rule out power supplies and relays. Nothing has been spilled on the switches. I will probably check the switches and clean them just to cover my butt however they fail at exactly the same time and commence working at exactly the same time which doesn't sound like dirty switches either.
Thanks for the replies.....

Windows are fused in pairs ie, right front and left rear and left front and right rear. If both of the rears are working and when you trey to actuate the front switches nad get no indication of current draw, then it's gotta be the power feed to the front window switches. I would pull them and check the sockets with a test light or volt meter. If you get no 12 volt source, then it's got to be wiring or soemthing either in the feed relay or the fuses. There aren't too many other choices. The probability of both motors failing at the same time is rather low, although the connectors in the doors could be at fault, but that will be a better proposition if the switch sockets show 12 volts with the test equipment. Good luck.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
