Noisy central locking - any ideas?

[Laurie_vr6 0]

Anyone had this before?

 

Every time i open the car, the central locking pump in the boot carries on hissing (pumping away i assume), for a good 15 seconds before switching itself off.

 

Could it be down to a fault on one of the locks, or could it be a fault in the pump itself?

 

Many thanks

could be

a leak in the pipe to one of the locks (either a split or just blown off connector)

a leaky lock cylinder

worn out vanes in the pump

or a jammed pressure sensor mech or microswitch in the pump

 

try disconnecting the pipe from the pump and block the outlet on the pump, then acticvate the locks if the pump cuts out straight away or after a couple of seconds like they should it points to a leak somewhere, if it still carries on going the problem is with the pump.

I think you must have air in the system, it's a common problem :D

How do you 'bleed' it?

:scratch: It's meant to have air in the system, they are air pressure/vacuum activated

YES It is vaccum operated!

 

My pump's done this for last 3 years.. don't worry!

in my experience, it means one of the vacuum lines has come off either one of the door mechs or of the connector in the foam casing for the CL pump.

 

pop the door cards off to check the door mech, peel the side carpets back to check the pump. Bish bash bosh.
