Window lock kills upfitter

[KUGSS]

Does anybody else have thw window child lock that shuts off the upfitter switchs? This seems kinda weird to me and my freinds.

[KUGSS]

Anybody there ?

I have upfitter switches. I have the automatic window lockout control on the driver door to prevent passenger and rear seat window control operation. My upfitter switches operate independent of the automatic window lockout control.

If your question is, "Should the window lock feature affect upfitter switch operation?"
The answer is, "No."

I would check the wiring harness for a short or loss of ground.

Or some one installed the upfitter switches later and taped into the Child lock power wire by mistake. You can trace the fitter harness back to its connection point and see if its factory or aftermarket.

I have the factory window sticker so i know they were not added later.

Do you mean you are the original owner and requested the upfitter switches with specific functions like high idle, off-road lights, air compressor, etc.? And these functions have always been disabled by the activation of the automatic window lock feature? Does the "original window sticker" indicate your upfitter switch functions?

I am very confused by the limited information provided for this malfunction. The upfitter switches are not all routed through the same fuse - or even the same size fuse - in the fuse block. Activation of the window lock feature disabling the switches almost exclusively indicates a short (not necessarily at the fuse block of course).

The owner's manual has a fuse block diagram (mine is page 218). Here is what my owner's manual indicates:
Upfitter Switch 1 = 30A fuse, block #108
Upfitter Switch 2 = 30A fuse, block #109
Upfitter Switch 3 = 10A fuse, block #3
Upfitter Switch 4 = 10A fuse, block #5
Door locks = 30A fuse, block #102
Power Windows = 30A fuse, block #601 (this is a larger sized fuse and lies between the upfitter switch fuses and the door lock fuse)

I provide this information to assist you in the tedious process of wire tracing and continuity checks. That is really the only way to determine the source of your electrical malfunction.

There is also a relay in the inside fusebox that is an Upfitter control relay, this would be a good place to check first because it is supposed to get power when the ignition is on.

[howell_jd]

The Upfitter Control with a full ISO relay is #305 while the Upfitter Control at #115 is a plain 20A fuse. These aren't as close in proximity to the upfitter swich fuses (although wiring harness issues only require wire-to-wire proximity to short).

Since there seems to be a connection to the window lock feature I suspect the relay is good - but always good to double check everything when running a problem to ground.

I got it worked out today. I was having a delay when the radio and the windows would work after starting the truck sometimes. I switched the delay relay and the relay for the upfitters andforgot about it. It just so happened that the upfitter switch lite up when i turned the window lock off. This was just a weird thing that happened and that made me think that tey were tied together. Thanks for all the help but i just need a new relay
