1994 Lexus ls400 replaced powersteering pump and won't shift out of park, no instrument lights no power windows, no power door locks, no power trunk release


Sounds like a major fuse blown.
Any wiring disconnected or stripped near the pump ?
Have you checked the major fuses around the battery and underhood fuse box ?

Trunk release button on 2001 ford focus will not work


So your trunk release button on the dash dpesn't seem to open the trunk.
Does your key fob button open the trunk? yes....then could be problem with switch but read on.
no......are your power door locks not working as well. not working.....check
fuse, on 2001 Focus the fuse is a 20amp number 63 on the back of the fuse panel under the dash. Pop cover off and undue the rwo screws. hold plastic retainers and pull off the fuse panel from metal frame. pull fuse panel down toand turn over so you can see the fuse.check fuse. blown? yes.......replace fuse with good one. test all door locks open/close then check fuse...if its blown the problem is something to do with the door lock circuits. if the fuse is still ok...try pushing the trunk open button. fuse still ok? then I am a loss toas to whats the problem but if the fiuse blew when trying the trunk button your problem is the trunk latch circuit.
Now if the trunk latch button is popping the fuse then disconnect wiring to
trunk latch (in trunk) and try the button again. Still blowing the it is the electrical before the trunk latch unit. If it did now blow the problem is something to do with the part of the circuit you disconnected.
How to go farther and find the problem exactly is not covered in this answer. You have to take it from here. JAG

I have not been able to lock or unlock my car using the key pad. The lights on my mirror does not work and I can't open the trunk. The car does not beep when trying to open the doors, trunk, etc.


you might possibly have an electical short in the drivers side door, look for moisture entering the door panel by taking off the interior panel, and looking for blown fuses in your fusebox

02 VW Jetta locks, remote, lights, windows stopped working


Same problem with an '03 Golf--remote entry, power windows, and interior lights stopped working. This was easily fixed by replacing fuse #14, (10 amp), located in the driver's side fuse block.

Electrical windows & door locks not working


Sounds like a possible BCM body controll module has shorted out partially. I think these are only at dealerships.
