I recently took my car out from winter storage. And found out that my blower was dead. I had some time research the problem yesterday. And found out that fuse 20(and only this fuse) was blown (7.5A). Replaced the fuse and the blower started up. But the fuse got blown again. I had no replacemant fuses. So I could not do any more. Later to day I will get some more fuses. Look at the schematics, and see what Google can come up with. But do any in here have some pointes what may be wrong.
I Have done some preliminary reading on the ElectricalTroubleshooting manual. I found out that the main module here is the IHKA module. But as I can see this module get its power several fuses(9,19,21,29). So if this module was the culprit. Then should we not expect that also other fuses like fuse numer 21 which is has the same rating. Also to be blown?
