did you have a question?which engine & transmission is in the jeep?2 or*****
.sorry for the delay.............Greetings...... “Hi, I’m Don (akaCustomer and I look forward to helping you!”.The Door Modules activate the Door Locks, Mirrors & WindowsWithout the use of Dealer Scan Tool you are limited to test Voltage, Ground &checking connectionsThe Door Modules are located inside the Front DoorsFuse "12" located in the PDC powers the Door ModuleTest Voltage on "both sides" of Fuse 12 with Key ONHere is Schematics

Still not able to complete the puzzle. So the driver door module is not getting 12v from the bcm
No.......the BCM sends a DATA Signal in the form of a Ground.....Not VoltageAs stated, Fuse "12" powers the Door Module, in which the Door Module is responsible for sending Voltage + & DATA GroundThe circuit to the Windows & Door Locks will be "Reversal Rest at Ground"meaning there are "2" wires that go to the Window Motor & Door LocksOne wire will have Voltage +.....one wire will have Ground - when the Switch is activated (up or down...lock or unlock)When the Switch is moved to the other direction, the wire that had Voltage + now has Ground -.......The wire that had Ground - now has Voltage +Typically it is the Door Module, but use of Dealer Scan Tool is needed to Test & ProgamYou may want to try disconnecting Battery Cables & touch the Battery Cables together "BRIEFLY" then reconnect to see if that RESET the Module
Not sure what you are trying to confirm, as I posted the procedures
That would be the YELLOW / VIOLETClick attachment
will be off line for a bit........thanks
sorry for the misunderstanding, but let me repeat........Fuse 12 powers the Door Module & from there powers the TAN / BLUE, which is the "Main Voltage + wire to operate the Windows, Locks & Mirrors from the Door ModuleThere is NO "low reference" wire, as the components are powered via 11.8 - 13 Volts DC
I need to find the resistance between fuse 12 and door module???
Resistance?.......you either have at least 11.8 Volts or you don't at the Door Module or Door Switch TAN / BLUE wire.,IF you don't, you would "back probe the TAN / BLUE wire to the Fuse Panel "Fuse 12", to locate the issue.Jeep is not very good on diagrams & Fuse 12 only powers the Door Module, Windows, Locks & Mirrors
