Alright. I've scored the internet for days trying to find an answer to this..
I've got an issue where the power windows on my 2005 F350 Crew cab will work when I have just turned on the key. But after using them for a few seconds, they stop. If I reach down after a while w/ the truck up, the 601 circuit breaker is HOT to the touch. I tried paying $20 for a new one, installed it and I'm having the same issue. I can turn the key off, pull the CB, blow on it for a few seconds, plug it back in, and the windows will work for a few more seconds (this is how I got them to go back up).
That's it. JUST the windows, EVERYTHING else works fine. Radio, instrument panel, power mirrors backup radar etc..
I've also tried swapping the "accessory Delay Relay" w/ the "Upfitter relay" to no avail, issue persists. I have a hard time thinking it's a loose connection somewhere because:
A) The windows just stop working w/ ANY physical movement in the truck
B) I can recreate the issue w/ ALL the power windows in the truck (4 windows, Moon roof, and rear power slider) on multiple switches throughout the truck (even the one on the dash for the rear slider and the one on the ceiling for the moon roof).
Does anyone have any other ideas? I REALLY don't wanna take this thing into Ford for $150 just to have them tell me I missed something.
The circuit breaker gets hot and opens for one reason: Too much current is being pulled through it. Only the power windows (including slider and moon roof) operate off this circuit breaker, so nothing else will be affected.
Does the circuit breaker also get hot when the truck moves regardless of whether the window switches are operated or not?
I'm thinking that you may have a pinched or chafed wire (circuit 400) that is shorting to chassis ground when the truck moves. Less likely might be a beverage was spilled into one of the door-mounted window switches or something else odd.
I am having a similar issue but I think mine is because the previous owner of this truck butchered the wiring somehow. My windows will work fine, radio will work fine also, then the next minute the radio and power windows won't work at all, then out of nowhere radio comes back on and windows work fine. Another oddity is that while the windows and radio aren't working if I turn my headlights on the clock which is on the radio works fine.
So nothing short of testing all the wires for the windows, is going to fix this issue? Ugh..
No, just the power feeds to the window circuits, most likely. That's why it's important to clearly and accurately describe the conditions under which the circuit breaker cycles. See my unanswered question in post # 2.
