  • Hello ,

    What is the Additional box Heater relay designation ( Hyundai Santa fe 2 / diesel 2.2 CRDI )
    My heated mirrors are working for 1 second afterwards they stop heating and I cannot find the designated relay that stops the functionality of the heated mirrors.

    Thanks a lot

  • PLEASE HELP ME!!! I spent two hours looking for flasher (turning signal) relay on a 2010 Hyundai Santa Fe GLS. I took the dash apart, kick plate fuse box inside, checked fuse box in engine compartment. None of which reads turninging signal relay, turn relay, flasher relay etc. Where is that relay?

    Thank you for any assistance you can give.
