The first thing to do would be to hook up a factory or professional type scan tool an check for DTC'S - diagnostic trouble code's . This vehicle has very complex electronic's. Serial data communication network,class2 data bus . There are electronic modules inside the door's that control the lock's ,power window's , power mirror's . Your best bet ,take it to a qualified repair shop . Not a fuse problem , driver an passenger door module each have thier own power supply. Two circuit breakers ,PWR/WDO circuit breaker 30 amp. You could check DRVMDL 10amp fuse ,located in the rear fuse box , PASSMDL 10amp fuse rear fuse box , RRDR/MDL 10 amp fuse rear fuse box . Rear fuse box is under the back seat . None of the window's , lock's etc.. work from any door switch ?
Sorry, you cannot test the modules unless you have a StarTeck or Launch scanner.
All modules can be replaced as long as it is not the Cluster, EIS or other coded module.
Seat modules have the highest failure rate.
If all fuses check out with a test lamp...( fuse designation usually paper page inside fuse cover ) then it may be a switch problem ie: sticky liquid spilt over switches. . Do all the other features work ?.
Have you checked for fuses under rear seat ?
Also, if there is rain water in the floor area this could cause this.
Windows need memory set by holding or pushing window switches for 5 more seconds after reaching travel limit.
You may have two separate issues here. First as for the brake lights not working I'm guessing they all went out at once. If so there is stop lamp switch located on the arm of the brake pedal. If this switch stopped working then you will not have any brake lights. The panel underneath the dash has to be pulled out in order to see the switch. As for the locks not working the pnuematic pump which supplies vacuum for the central locking to work may have either quit working or shut down due to a vacuum leak in one of the vacuum elements. To check this go to the fuse panel in the trunk and look for the fuse for central locking and remove it for a few seconds and re insert. This will reset the pump and allow it to work again. Try the locks a few times to see if they are working. If they don't work right away then you may have a bad vacuum pump for the central locking. The central locking pump is located under the rear seat cushion on the passenger side. Hope this info helps you out if not let me know and I will try to do what I can to assist you.
okay the dealer may be right,the wiring sometimes breaks from opening and closing trunk,the trunk release operates on the same power as door locks, if door locks work its not a fuse,check the wiring harness in the trunk near hinge, this system is a complex one,so if you dont see a broken wire in the harness,(you will have to untape the wiring to see every wire) have a tech check the system.
If all power devices stopped at the same time you may have a bad fuse link. Since it is rare for all the fuses blowing at once and you already checked them. Start at your fuse links before assuming something expensive.
There are 2 pneumatic pumps in your vehicle. one is vacuum and is for your central locking, located under your rear seat bench. The other is pressure and is called your closing assist pump. It is in the trunk behind the rear liner. It also operates you reverse antennas(optional). Your doors and trunk lid are closed by pressure valves that work like little teeter totters. There is an updated relay called a convenience relay located in the right side of the trunk. It stores all the window paramers(for express up and down) as well as your closing assist parameters. In the right side of the trunk there is a fuse box. If you remove the closing assist fuse( I beleive it is # 15) for 15 seconds and then reinstall it, the parameters for your closing assist will be reset. It is possible that your vehicle already has the updated relay(called a relay but actually a microprocessor) and there is a leak in the system. After reinstalling the fuse you can see what doesn't work( one of the doors or trunk,reverse antenna) and isolate the faulty component. If everything works o.k. let it be because they have always been problematic and when they happen to fail just reset it. hopefully I have been helpful.
