  • Hello
    I am wanting to know if my Sprinter 2005 has a relay fuse for the heater blower fan other than the the fuse numbered 21?
    Are the fuses located under the driver side seat relay fuses and would one be for the heater blower fan? There are 3 in your diagram K26, K61, K87.
    I have replaced the variable resistor and the blower fan is working.

  • Where is the inhibitor relay located on a Mercedes sprinter 2002?

  • Sprinter 2003 2.7 Cdi 216, I’m looking for relay of horn, the fuse is number 7 and is ok, and relay I suppose is K14 but i don’t know where is it:
    Thanks and regards
