So for awhile now ive had no Cargo lights in My truck. Its a 07 2500 QC. Ive checked the obvious out. Fuses, bulbs, and even bought a new HL switch. Boy i wish the switches were simple like the older dodges. the new HL has a board in it. but its not that and i have a spare one now. Ok so anyways. Ive tested everything i could easily get to with a multi meter and heres what i get. battery just over twelve volts. wires coming out of fuse 26 same. then i beleive it goes to the dash cluster. couldnt get to that to test any thing back there. the number 6 pin coming out of the HL switch which is for the cargo light only shows 11.4 v when ground to the steel under the dash. But then the wire that runs up the drivers side pillar and the pin outs for the lights at the back only read 8.4v. By looking at the wiring diagrams im not even sure really how the switch tells the lights to come on. it doesnt show where it conects to the cuircit anywhere from what i can see... no cargo lamp light comes on on the dash, they dont come on when you push the button or turn the roller switch all the way up or when you open the door either. anyone got any ideas? any help would be great guys thanks. not the greatest with electrical but its getting way hard the more stuff they throw in there.
