Hi, I have a 98 new beetle. A few days ago my Heater A/C switch wouldn't turn, now it turns but the fan is stuck on low all the time. I have a new switch and am installing it, but my car overheated yesterday. I figured out my radiator fan fuse was blown (on top of the battery) and replaced it, but it had melted some of the plastic. When I put the new fuse in the fan started running. Now, however, I don't think the fan is coming on at all and the fuse doesn't appear to be blown again. Are these problems linked? What could cause the radiator fan fuse to blow? Any suggestions? Help please!
