ok seriously need help...

If you have a multimeter that measures current (A), you could connect the meter leads in place of the fuse to see how much current is being drawn on that circuit. If you do not, disconnect the battery and measure the resistance (ohms) between one of the fuse holes (the little holes in the top of a plugged in fuse) and ground.

Great, my ground is not messed up!

I actually did what you said about the multimeter, but not sure if I was doing it right. I switched the car on to ACC position, so that supposedly the fans would come on. But without the fuse, no air was coming out, I turn the A setting to 10m, it's giving me 36amps.

But when i do the same to the cigarette lighter fuse, again with the fuse unplugged and I stuck the two probes in the fuse socket, it's showing me 1 (i guess infinity it means). Isn't this suppose to give me 15amps or less (rated fuse is 15amps)

So what should be the normal amps if there is no short??

Thanks

You typically have to move the leads to another set of holes when measuring current. 10m for current would be 10 mA, which is very little current, so you are overloading the meter. You should have the meter set to its highest current rating (which is probably only 10A).

Here is how my multi looks:

Are you saying one lead goes to the gauge socket, the other lead goes to another empty socket?

I measured this was the same result as I measure from both leads to the same gauge socket

result were:
200 - 1
2000 - 1
20m - 1
200m - 36.7
10A - 0.04

So it's less than 0.04A I suppose, while the car is in ACC mode.

I hope this is the right figures? I am going to unplug the camera and put the car in reverse and see what the Amp says.

You need to turn the knob to 10A. You clipped the bottom, so I can't see the holes, but it looks like there is a 10A hole on the left. One lead goes there and the other in common.
