My Zafira A was involved in an accident. The damage appeared to be mainly superficial. I had to replace all the driver side panels. I noticed that after the accident the front driverside, side light and rear light would blow quite often and need replacing. This carried on for a while and was mildly inconvenient. But now those two lights have stopped working completely. I have checked all the fuses. And I have checked the connections with a multi-meter. But both are showing zero volts. Any suggestions on what might be the cause would me gratefully appreciated.
