    i replace the burnt fuse a few days ago and it will continue to burn out within a day or so which will not allow any of the doors to open. i have to use the key to enter the car.

    I put the new fuse in its locking fine with the key entry and with the remote entry.with the key it opens and close's fine with the remote same thing, i stared pulling on the boot's in the inside of door and the fuse has not burned out yet. i'm trying all for doors fuse has not burnt out yet. could it be a bad relay? you can hear something clicking after the fuse burns out.

After you replace the fuse try closing the door and put the key in and turn it back and forth locking and unlocking it and see what happens when you use the power lock

You have a short Somewhere. Check inside the Door where the Harness goes into the Doors. It is the Black Flex duct that looks like a Vacuum hose.

    On the Housing that I described earlier. Grab it and move it around, If the Fault is at that Door it Should Blow the Fuse. Get some Extra Fuses for this Process.

Why does the fuse immediately blow on my power door locks? how to fix this?


You have a short somewhere in the system. Maybe one of the lock actuators or a switch. To test disconnect all locks and switch then replace fuse if don't blow start with driver door and reconnect lock check fuse see if it blew if not reconnect switch active lock check fuse see if ok. Continue with each door separate using same steps until fuse no good you will have found short. Replace shorted part.

Jeep keeps blowing fuse


You have a dead short and yes it could be in one of the door lock switches, figure out which one is blowing the fuses and take it out, might just have a wire that came loose in the back and is causing it to short out when you hit the switch button.

M38 fuse keep blowing


the parts are shorted, the FUSE stops the fire. and flames.
we fix this buy isolating the shorted part.
we do that with an ammeter. (there are other ways, ask)
i see the ammeter prove short then
i try each door manually , 1 by one form the local door switch lock
to see if one door blows the fuse when activated.
BINGO, so then unplug that door lock solenoid, still blow the fuse
(i use a fuse substitute device (sold in all good auto-stores) called a fuse, circuit breaker converter)
lock sol, removed, still blows?, yes? then harness shorts, (hard work)
if Sol, pulled cures over-current, its bad. a shorted soleniod.

there are other ways, ill just list them.
no ammeter?
no C-Breaker.?
  1. use a light bulb in place of fuse. (i use a head light in a box)
  2. a current limited power supply in place of fuse. (see over current)
  3. Pul all parts, 1 by one on this bad line and a box of fuses.
there are 4 ways.
I always use an amp clamp meter on the line
and the circuit breaker trick.
then pull parts. and conn. on the bad feed. (lots there are)

that's it, for shorts.

My interior light fuse keeps blowing on my 1983 Lincoln continental mark 6


Your car has quite a few things tied into that circuit. I believe it's a 15 amp fuse you are referring to. that is what that circuit is calling for.
I feeds into the headlight switch where it then runs the dash lights, auto delay exit light. Power door locks, illuminated entry module, LT and RT door switches, door lights, lights under seats, glove box light, engine compartment light, trunk light, lights on warning chime, antitheft system, clock(analogue dash only), radio, cigarette lighter lights and courtesy light switch.
Light bulbs can cause fuses to blow. If the fuse blows imediately you have a dead short somewhere. You can buy a circuit breaker to put in place of the fuse and it will take longer to blow than the fuse unless it is a serious short. I would first suspect a bulb. Start removing them 1 X 1 starting with the dome light. Note: also try putting the dome light switch in different positions, the cigarette lighters, remove them. All the bulbs you have easy access to, remove and reinstall if the problem is still there.
You can only go so far before it is going to take a professional to solve the problem. Electrical problems are among the more difficult for an untrained person to diagnose and fix. You can deal with the obvious and simple things, but you can actually do more harm then help if you start digging without knowing what you are doing. EVEN POOR GROUNDING OF A CIRCUIT CAN CAUSE HIGH RESISTANCE AND CAUSE A FUSE TO BLOW.
I hope I have given you some understanding of what is going on. Your car is one of the more complex ones to works on in certain areas.

Unplug cigarette lighter, check circuit, unplug each door individualy at first, Don't forget the back doors, check circuit. Usualy the door wiring is damaged but there may be more then two cigarette lightes depending on the model.

Problems with Auto Lock Continually Blowing Fuse


Hello Zoeno
Well in my experience it sure sounds like a bad wire in the wiring in the door jam. I have seen that happen before from the door shutting and opening all the time, I think there is a way to check it, if you put a fuse back in it and try using the passenger door to get in and out. If the fuse don't blow again after using the other door (drivers side) you have found your problem. I don't understand why GM would even change your fuse box for that it doesn't make any sense, I have been a shop owner for 11years now and a mechanic for 20 years and have seen many problem with electrical systems and when a fuse blows it is usually a bare wire touching somewhere in the system, also there is a relay for just about everything in that car, and could be a problem too. I know it may be a inconveniance to go thru the other door but it should help figure out if its the wiring in that drivers door or not. I sure hope that helps you out some, Thanks for using FixYa.com Bear001
