I have a 1997 bmw 318i. the central locking system keeps blowing the fuse. i know there is a short somewhere,but where

You have a short somewhere. You'll need to remove the system and test to figure out where the short is. It could be in the unit or in one of the wires leading to the unit.

change the central locking relay.

There is a short somewhere, do you have an after market stereo? Look for a short, or grounding out

try locking and unlocking the car with the key 3 times slowly ,other than that i have no idea ?? another trick is to disconnect battery and join the cables together for a few minutes to discharge any capacitors that may be holding a charge in the computer..Only other thing i can think of is the main dealers who have the right connectors and software to re set it all .sorry i havent been of any help

hi

I had this problem before. There could be several reason.

1-Your air conditionner filter could be soo old and dirty, that you don"t get that good air condition.

2-Your air cond compressor could be giving low pression and so, no cool air.

3- You could be having a leak somewhere and so you're loosing gaz after it's filled.

4- Check also the fuse box. Seee if the AC fuse is not burnt.

thanx and don't hesitate to come back to me

REPLACE THE HEADLIGHT FUSE IN THE FUSE BOX TO ALLOCATE THE RELAY SWITCH ON THE LIGHTS AND WHEN IT IS ON REMOVE THE RELAY ONE BY TO ALLOCATE THE RELAY .REPLACDE THE FAULTY RELAY

you have to figure out where there is a short in your wiring--follow wires, look for broken, missing insulation--if it started in lights, look there first maybe. Also check the connections of plugs. Good luck it may take some searching.

simple your mechanism on the inside of the boot(catch mech) is spring loaded.just spray copious amounts of wd40 deep inside. if that dosent work then your catch/keep is twisted.

Oxygen sensor (Only 1) located in exhaust system, on passenger side, below front seating area. countrycurt0

you can take the fuse out from under ther bonnet and open and close the doors manually(boot may not open though), the fault is with one of the locking mechenisms in any door
