  • what and where is relay for indicaters/hazard flashers reason is my flashers are coming on then going off for no reason, engine runing or not.

  • Ok do a few questions, so first there is a loose red wire in the rear compartment in the none rec area, what is it for.

    also in my spec there is no front fog wire from the swith plug to the clocks, i assume thiscan be added by removing the plug and adding it into the correct pin (assume the power to all wires in the switch take the power from one feed in the switch wire plug?) i assume this wire goes from switch to clocks? so once activated with opcom the clocks should work? zafira b 1.6 2008 by the way

  • Hello, my compressor is working only while test it direct from battery and have checked if there is any disconnections but couldn’t find any
