Damn! What a pain. Funny you mentioned A/C, as that does not work either! I did replace the heater valve a few years back, as the AC did not work at that time either! In my case, one fan stopped working. A couple of weeks later the second fan stopped as well. The cold air from the A/C stopped before to the second fan quit?? I checked the fuses that you mentioned right away and they were in tact? It must be the resistor that you mentioned. Do you happen to have a name/part number for the resistor in question? I am from the US but currently in Chile and trying to get an answer here is like pulling teeth. These geeks wanted 1,200.00 USD for a replacement fan!!!
