how can I fix my Neff cooker hood E-NR D8901NOGB (16 yrs old)?
 
                The lights on my hood started to blink, so replaced the bulbs, but problem persisted and they then went out.   If I fiddle with the switch they still flash but won't stay on.  The fan continues to work well.  I need to  find a way to take hood apart to investigate and clean.
