Hello Ford F150 owners. New member who reads this site and benefits from others experiences. My power windows started acting up and would only work at various times. The windows would work sometimes but once the truck was turned off and back on they would not. It was both drivers and passengers. Ford dealer guy says it doesn't sound like the relay and wanted the truck to come in but I can't afford several hundred bucks so I used this site and others and started breaking it down. I thought it must be the switches so I changed out the drivers side switch set for 28 bucks, nope! Next was the relay number 49 in the drivers compartment fuse panel. I called my favorite dealer, 30 bucks, could buy it online or at one of the local parts shops for about 20 but I called the closest dealer, whom I don't like, and they had it for 20 bucks, a Ford part, good enough for me. That worked! Earlier my windshield wipers had quit working and I replaced the relay to fix that as well but I don't mind replacing the switch set because everyone says they eventually corrode. Side note: a guy on youtube figured out how to take apart his switch set and clean the contacts to fix his problem. Of course I came across it after ordering my set. Good luck! (59,000 miles on my original Hankooks, first time past 36K on dealer tires ever!)
I have the same problem and mine has started getting to the point where it happens almost every time I start my truck.
I looked for relay 49 but only one I could find is the one in the passenger side compartment that's labeled "delayed accessory" . There's also 48 in the same compartment that's labeled "circuit breaker: power windows, power sliding back window", could this be the one?
Really need to get this fixed asap so any help is appreciated.
Got the same problem with 2011 F150 screw; started last week, now nothing goes up or down and drv window partially up. Anyone have directions to get to main switch since none work I expect that that is the problem or harness.
Replaced the relay at #49 (delayed accessory) in fuse box and all's well again.
Had the same issue after fixing my driver door lock switch, happened to be a bad fuse #32. Swapped out and now it’s good. 15 amp fuse #32 passenger fuse box 2011 passenger fuse box diagram
Just checking to see if anyone else is having issue with their power windows not working. Yesterday morning my driver side window would not do anything. Called the dealer and set up an appointment for them to look at it. Well I stopped by the gas station on the way to work and when I got back in the truck I tried the window again. It worked this time.
Didn't think much about it and was about to cancel my appointment, but thought I would ask my buddy if he had any issues with his 2011 F150 power windows. He said yes actually he has had his windows not work a few times, but it was mostly the passenger side window. Said that when he turned his off and then started it back up the windows would always work. Sounds just like mine, but a different window.
So, I go into the dealer this morning and already knew what they were going to say. "If we can't replicate the problem then we have no where to start trying to diagnosis the problem." I understand that and will just take it back when it does it the next time and not turn the truck off.
Just trying to see if anyone else has had this happen to them. There has to be something that is not right, or it wouldn't do the same thing in other trucks.
I have the EXACT same problem. I replaced the switch on the driver's side and it worked but now is not working again. I need help!
