Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
If you replaced the module then yes it does require programming. I would call around to a few GM dealers any GMC buick chevy or caddy dealer can reprogram it and what their base charge is can vary a lot. How did you decide the module was bad?
can yous send me your vin and build date as well as the part number you replaced, there are a couple bulletins on part redesigns and application from 07-09 models
ok so your good there. That is just a latch not the module so you wont need to program it. If it is still inop Start by hooking a testlight to the brown wire on the latch connector and to ground then using the interior switch command it open and see if the testlight lights up
ok so above the headliner near the middle there will be a gray 22 pin connector (2 rows of 11) there there is onlyone brown wire in it, unplug it and the latch and ohm the brown wire end to end check for <5 ohms. also towards the passengerside where the harness goes through the roof check the wire there for having rubbed through.
not likely, he probably found too much voltage drop in the cables it can cause some weird anomalies but if they were replaced you should be fine there. make sure to check where the wires go throught the metal from inside because where they come out at the boot to the liftgate is a different layer its usually the inner one they rub on.
