What would cause no power to fuse box just on the cooling fan fuse everything else works in fuse box but the slot for cooling fan fuse is good made jumpers for fan fan works any ideals
How hot does your temp gauge read before you think the fan should turn on? mine doesn't until its about 3/4's of the way to "H". if you are reaching "H" or close to it and it doesn't turn on, check both sides of the fuse for voltage with a digital multimeter. Key should be on and you should be holding your negative probe to the negative terminal on the battery and the positive probe to check voltage with. if you have battery voltage on both sides of the fuse, I would lean towards the fan switch on the radiator as being faulty. if you do NOT have voltage on either side of the fuse, you could be having a problem with your ignition switch. if you have voltage on only one side of the fuse, it means your fuse is blown or you have a connectivity problem at the fuse holder.
