@rollinporch There should be two large leads and two small leads. If your fan has a metal heat sink it will burn out when connected directly to power. Those need a special fan controller. Go to Moparts.com and look in the Hot Deals and New Products forum. There is a thread on Mercedes Fan Controller. It has all the details.
im using a double fan that i took of an old mercedes to cool down the interior of my car (which has no a/c) ..is this single fan more powerful than the double ones?
btw, is good to know how many amps its drawing... today i blow up a 30 amp fuse. Now I know why.
Either that fan is fubar or you have your polarity reversed but that fan is spinning the wrong way mate! look at the angles of the fan blades and think about which way it will be directing air!
@JOHNYSMITH1302 The fan is definitely spinning the correct way. It may look like it's spinning incorrectly but it's moving the way Bosch designed. You can not reverse the polarity on these. I tried that just for giggles. It burned the wires but the fan did not move. I work with Mercedes all day long and know these fans well.
@doctormcgoveran The fan will flash momentarily to 50 amps on start up. It's only that high to see the numbers flash on the meter. It settles down and runs at 39 amps.
@thefeets1 i have a problem, ***HELP****... my autel scanner shows the temp at 100 degrees celsius but also shows that the engine desired fan speed at 0% but i can activate the fan to 90% with the scanner.. i know the fan is 10% good, why wont the car demand the fan on? it sees a coolant temp of over 100 degrees celsius
@JOHNYSMITH1302 think of it these way if it was the so called right way than that thing would most likely fly of the table or with it if it was attached
The large wire on the left is positive. The other is ground. The small wire on the right is a trigger that turns on the fan when connected to 12 volts. To make it run in the video, I jumped it to the positive lead.
i have a fan with 4 wires 3 large then a small control wire how can i hook this direct to turn on with a switch

@rollinporch I have no idea which fan you are working on. That makes it impossible for me to know.

@thefeets1 think of it these way if it was the so called right way than that thing would most likely fly of the table or with it if it was attached
