    i actually got this fixed. It hasn't messed up since I had it in the shop anyway. They said it was my lock cylinder. They also replaced my BCM again. They put in a circuit breaker thing where the fuse was and I haven't had any trouble since!

Do not replace a fuse with a bigger one unless posted in a TSB or told by manufac. You could easily fry your systems by attempting to simply putting a bigger fuse in

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 ?

Power Locks dont work and neither does the trunk release


My car has a fuse box near the battery. when you take the cover off there is a map under the cover to show what all the fuses and relays are. I would check the fuses.

Power options not working


Check for a blown fuse, Owners manual should show you the location of the interior fuse block if you are not sure.

Many times the power accesories are all on one fuse.

You should also check to see what caused it to blow initially. Many times it can be the car adapter for the celphone when they fail. Otherwise look for damaged wiring, especially ar the door to body harness bundles.

Electric door locks, trunk release, courtesy lights and rear window defroster have quit all at once


The first thing to check that can affect all of those things at once would be the "BODY" fuse. This is a 15 Amp fuse, located in the rear fuse block. The rear fuse block is located under the rear seat.

If this fuse is blown, you need to have the circuits diagnosed to find out why. Failure to locate and repair the CAUSE of the fuse blowing will only result in the fuse blowing again.

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

Interior wiring in drivers door. Radio, mirror lights, dome light on console, trunk light, power door locks and electric mirror switches don't seem to work. I suspect a fuse, #4 20 amp. under the hood and...


do you have an aftermarket stereo? if you do, unplug it and see how long the fuses last. check your lighter and make sure there are no foreing object in there that can cause a short. when you replace the fuses, take notice of which action causes the fuses to blow... for example, door lock unlock, are they still ok, door lock, lock..check again, mirror left, still ok, so forth and so on. take it one at a time and see which action causes them to blow. when they blow do it again to see if the same action that caused them to blow the first time did it again, then trace those wires. you probably have a bad relay somewhere.

2005 Subaru Legacy electrical repair question?


The #3 fuse does service both windows and door locks and #2 services a control module that affects door locks. Inspect them closely since the fuse element can crack when blowing and this is much harder to see. Pull a least #3 and plug it back in in case the contact blades have stopped comunicating with the mating connector.

To troubleshoot this effectively, you really need a cheap multimeter and the Haynes service manual for your car, #89101.
The manual has very good electrical diagrams in section 12 so you can logically trace the problem. They are available at most every auto parts chain store and cost ~ $20-25 US.

Fuse blowing on contact


find the short circuit, to do this disconnect the systems the fuse supplies power to one at a time until u isolate the one that is shorted to ground, then it is matter of checking the wiring harness until u find the damaged wiring.
