AC Fuse Blowing

Hello all, just had a problem with the D4, the Air Condition fuse under the glovebox is blowing , did anyone had that issue before??

Where should I start looking ??

I am in the southern hemisphere so its pretty important right now.

Old trick is to pull the fuse, get two small blade terminals that will fit into the fuse holder slots, then solder a couple of wires onto the tabs, then attach a bright bulb, turn a/c on and the bult should light.
Then start unpluggibg stuff until the bulb goes out, either a dead short or a component failure.

It is not foolproof, but is simple and works.
I use a headlight bulb, but you have to be careful, as the heat from the bulb can melt plastic.

Will work on that tomorrow, perhaps an ampmeter could work there too, Will like to have the Electrical Drawings of the AC to simplify the fault search.
