Rear Cab lights not working

[crbourret]

I have a 2019 2638 HST w/Cab and my rear cab work lights are not working. The bulbs are good and the switch lights up when I press it and all other functions from the switch work such as the front cab lights & wipers. I've checked the work lamp fuse and it is good. I found a wiring diagram and it looks like there are relays that feed power to the lights. My question is does anyone know where the relays are located before I start tearing the cab apart looking for them?
Any help would be appreciated.
Thanks

i have the same machine. so far so good with the lights... i can send you a link to my PDF service manual if you would like. also easiest access to the roof components is to remove the 4-5 bolts on the out side that hold the red roof cover on. but i don't think it would be in there unless the switch is buggered. there should be fuses up front i think or at the bottom of the steering colum.

Thanks, Someone else sent me the PDF service manual. The fuse under the steering column checked good. There is a relay pack up above the headliner that the dealer told me about. After checking it all out and plugging everything back in they are now working. I'm guessing it was just a loose connector or something like that.
