Do none genuine relays work ok on a D9 .. to replace the one's that control
the rad fan or is it back to the main stealers to get shafted up the bum over price
they do work provided you install the relays with sufficient amp.. but you should look for the circuit diagram printed on the relay. if that has diod signs better to go for originals. for rad fan relays one should be bipass relay which passes current in the off position and the two other will be 4 pin ordinary relays.
