Central locking not working

Recommended Posts

I have a problem with the central locking on my Corrado. When I lock the car only the driver's door locks, but I can hear the pump running on for a while after. If I press the passenger lock down it goes down quite easily as if it's trying to go down but needs a hand. If I unlock the car from the drivers side with the other door and boot locked, it will unlock them all. The pump will also run on for while after even though everything is unlocked.

 

Does it sound like the pump is going or could it be the pipes?

Sounds like an air leak in the pipes. Check the connector(s) at the pump and door mechs first before having to trace the pipes between

Would also check to see if the pump itself is weak. Take off the connector and trying blowing down the pipe, it should unlock the car with not much effort

Cool, which connector and which pipe? Am I blowing towards the pump or from the pump the the handles?

Ah, the connector at the pump end in the boot. Sucking (oh err) should also lock the car. If it takes a lot of effort you have a leak somewhere, if its easy(ish) then the pump may be goosed.

Got you, makes perfect sense. Will do that first before taking the door cards off and searching around.

My central locking is really annoying right now. It will unlock but locking from the fob will not work, but the alarm gets set. 

When i then manually lock the doors they stay locked until the second pulse from the central locking pump which then unlocks the doors! If i then lock them manually they will unlock again 30 seconds later. Its as though there is pressure in the system which is constantly pushing the locks back up.

At the moment I've locked the doors manually without using the fob and they've stayed closed so far. 

Not sure what I'm looking for tbh so any suggestions welcomed

Thanks

Hasan
