Interior AC Fuse keeps blowing (10Amp)
 

So I have a 2000 Nissan Maxima, and all of a sudden my AC doesn't power on. I realized that the fuse was blown so I placed a new one in, and it blew as soon as I tried to power on the AC unit.

Does anyone seem to know what the issue could be?​​​​​​

• Low refrigerant?
• Wiring shortage?

Low refrigerant will not cause a fuse to clow.

A short in the wiring could and so could a defective part somewhere in the a/c stuff.

Exactly which fuse is it?

Unplug the wires from the a/c compressor, put in another fuse and turn on the a/c. Let us know if the fuse blows.

Could it be a bad blower motor?

And the fuse that is blowing is the 10 AMP (AC) Fuse in the fuse panel inside the car.

Not the blower motor. Those fuses are under the hood.

The fuse that is blowing is used by the control panel in the dash, the energizing coil of the a/c relay and the motors that control the air outlets.

If you haven't unplugged the a/c compressor yet, hold off doing that. Do the following things first. Depending on which step does not blow the fuse, we'll go from there.

You can (in the order of easiness to do):
1) pull the a/c relay out and see if the fuse still blows.
2) unplug the 3 air duct motors and see if the fuse still blows
3) replace the control panel and see if the fuse still blows.

I've done all of the steps, and the fuse still pops, unfortunately.
So I found another thread in the forums, with the same issues I'm currently having. And I'm starting to wonder it could be the AC Auto Amplifier because when I pulled it out it had water on it somehow.

When you say a/c auto amplifier, that means your car has the auto climate control system.

If steps 1 and 2 in my previous post still blew the fuse, then the control panel that is called the a/c auto amplifier is probably the problem. Notice that my step 3 says replace the control panel.

I don't know if you can still buy a new a/c auto amplifier from Nissan, but it would be very expensive. Go to a pick & pull junk yard and get one from there.

I did step 1 and pulled the a/c relay and the fuse did not blow!!
what does this mean?
