Mercedes ML320,2009.Wiper on/of relay( f58kB)has short circuit to graud 902A.Wiper not working.

Update on ultimate fix for this from my other comments, one of the prongs inside fuse box was not actually in-between the relay pin, so when taking fuse box apart and plastic top off, put the relay on to make sure all the pins are in-between and use pliers to bend to fit if not, also get some rubbing alcohol and a q-tip and clean electrical contacts for oil and dirt, finally line works again after doing this, and I didn't snip any wires and reduce the resale value of the car like Mr nigga fix 😎

I found out how to fix the problem, for anyone who had this problem, if you don't want to solder wires like this nigga, you need to take the fuse box out of the engine, take a photo of it, then take all he fuses and relays off, open it up, was a bit tricky but it pops off from the bottom, not the top, with a flat head screw driver on 5 clips, from there you use a pair of pliers and tighter all the connectors together, so when you put that relay back in, it's very tight. I also used a metal brush and sand paper for all the connections just because was so much work anyway to take apart, also sand the relay pins, any oil acts like a insulator, then after put all back together, works perfectly, better than this nigga fix, but thanks anyways

not related to this issue in any way unortunately

@@taiperas it's the exact same issue, I used a car scanner to check it, the relay prongs are too far apart inside the fuse box, need pliers to tighten them so they connect to the relay, or put solder on the relay to make the prongs bigger, or do as this guy did with the wires but is more trouble

@@taiperas 902a f58kb code short circuit to ground is same thing, after u try, the relay goes back in very tightly, probably takes about an hour total to remove and put back

Another way to fix I did after because the car vibrations makes the fuse box pins open circuit again so I took a tin foil pie plate and carefully cut out pieces and put over each relay prong, took 2 tries because first time too much tin foil, but wipers work again, so is another option instead of cutting wires like Mr nigga fix 😎

@@taiperas Another update this problem goes down the wire through connection x25-2 then into front SAM. You need to clean these connections as well and check online how to access them. I studied the wiring diagrams. MR Nigga Fix had too much fried chicken in car so is possible the oils got into the pins and acted like an insulator. Also a low/weak batter can cause more electrical problems. Also the fuse box like i suggested earlier needs to be cleaned and contacts tightened, each of these in this message all add up to resistance. Mr nigga fix too embarrassed to reply because pretty sure his method stopped working after around a month because also need to find these contacts and clean them if your battery is weak or car is older. X25-2 is under front seat foot area, so is possible BBC sat there and kicked connection lose. Front Sam for mine is beside battery under front seat, and could have battery acid corrosion or in the video maybe yours has Popeyes chicken like Mr nigga fix 😎
