Hi Guys, My passenger door lock is bouncing. I have read all threads on this and some info is very contradictory. I now have the correct spring for the internal repair and im happy with this part. Removing the lock however is confusing. -Am I correct in saying that there is an airbag behind my passenger door card? -Do I NEED to remove it to access the lock and remove it for repair -Do I NEED to disconnect the battery (this being a w203 early 2002) will this then damage my rear SAM unit as others have said? -Is it worth doing the spring repair or getting a new actuator and fitting a whole "new unit" Sorry if i am being over the top but I want to get this right first time.
