After a short drive, my wife parked our 2006 Elantra GLS in the
garage. A couple of hours later, she left to run an errand, and the
blower, or cabin A/C and heater fan didn't work. Of course, it had
been working previously. You can here a "Click" when you turn the fan
control clockwise from the OFF position, but the fan doesn't run in
any fan speed position.

Upon her return, I checked the relay, fuse, and fusible link box under
the hood, and the "30A blower fusible link" is open. Does anyone have
any ideas based upon experience? Blowing a 30A fusible link -- some
serious current was drawn. The blower motor never sounded problematic
before, but I guess it could be the motor itself, or perhaps some
control circuit??

If it's the motor, I hope it's not hard to access, as I don't want my
dash all scratched up or messed upon during repair.

Thanks,
Don

I took the Elantra into the local Hyundai dealer this morning, and
they just replaced the 30A Fusible Link, and all was apparently fine.
They said the blower motor checked out OK. Hmm . . I'm leaving on a
trip soon and sure wouldn't want the blower to crap out during winter
driving. Unless something was temporarily stuck in the squirrel cage
blower wheel, such as a pine needle or something similar, I have to
wonder about their approach to diagnosing the problem. If the motor
stalled due to such a scenario, I guess the stall current could be
high enough to blow the fusible link. We shall see.

1970s era Chryslers used a lot of fusible links and they seemed to
routinely fail. My dad replaced them often and nothing else ever
appeared to be wrong. We carried spares just like fuses although for
reasos unknown to me, the fuses seemed much more reliable than the
fusible links (which makes no sense to me as an EE, but seemed to be the
case).
