Central Lock problem 99 E36
I have 1999 E36 RHD 318i 4 door auto sedan and the central locking is not working properly. Sometimes it works fine 3 or 4 time then only the drivers door will function. Where do I find the CLU to have it checked/replaced, and is the CLU serviceable, i.e. does it have connectors etc that can cleaned or adjusted? grateful for any help.
