Hi -- I have a 2010 Extended cab F-150. Recently all 4 windows would not work. A day later they worked. Then stopped working again.
When it was acting up, none of the windows would operate, and it did not matter which switches I tried -- none of them would work. Then when they started working again, all switches and all windows worked.
Everything works, or nothing works. So to me, it can't be switch-related or motor-related because whatever the problem is affects everything.
After reading the owners manual I learned that there is a circuit breaker in a panel under the dash (passenger side). I replaced the breaker and it seemed to solve the problem for several days. Then they stopped working again. Most of the time, simply pulling the breaker out of the panel and reinserting it gets it working again. But I still have this intermittent problem.

Any ideas?

Thanks for any help.

 

Follow-up. In this forum I learned about the Delayed Accessory Relay (DAR), which feeds the 30A circuit breaker I already replaced once. So I went to the Ford dealer and bought this DAR and installed it. All is working right now - the test is time.

 

Thanks for the update.
