  • very good but not a precise match for my 2003 combo mk2. But so mutch better than info. I got from arnold clarks parts dept. Keep up the good work.

  • what is the spec on R3, R4, R5, R6 in the second picture?

  • Thanks for your reply, I found the double relay in a sealed box next to the battery, which was secured by 7 long hex screws (very awkward to get at). The yellow plastic relay, covers both left and right indicators and hazard lights apparently. Confirmation was made apparent via my order for a replacement on amazon @ £12.99; the cost makes it worth a try!

    Your first picture shows the location @ top right-hand corner, just beneath the windscreen.
    No Heinz manual available, as too-few Vauxhall Combos’ made to warrant the publishing cost apparently. Its an 1.7lt Astra engine, shoe-horned into a Corsa, made as a van…

    Am very grateful for your help and for making this information available, its more than Vauxhall provide!
