Power door lock help needed.
After the salt bath, my door locks quit working. I have since removed two bad actuators, front passenger and rear hatch, and tested all actuators with a 12v source and they are working. With everything put back in and wired up, I get nothing when I push the door lock/unlock. Windows and power mirrors work fine.
I have checked all of the fuses none of which were blown. I read that the whole power door lock system is controlled by the passenger front control panel on the door panel. There are two relays in the door switch panel.
Is there anyway to test this panel to see if that is my problem?

All of the switches' lights are working also. Meaning the little light in the middle of the window and door lock switches.
I found this, so it should help.

5W30 whatever is fine for most of the lower 48. If you're buying synthetic anyway 0W30 is a great idea. As far as brand goes... whatever your Jeep likes best. 4.0 isn't exactly high tolerance, though if there's only 43k on it you might realize longer oil change intervals if the rings are in good shape and you run a larger filter like M1-301 (unlike a 300,000 mi engine on original rings... not really worth it lol)

Yeah i would say try different brands and see what your engine likes the best. Had RP in mine, changed it to M1 when i couldn't afford Royal Purple and my Happy XJ turned into a pissed XJ. the lifter tick is sooo bad right now, and it was nice n quiet with RP.
