I have a 2000 Hyundai Accent GL. The heater fan/blower will not work. I have switched out relays/fuses. Change the resistor. The blower its self will work if straight wired. When plugged in and the switch is on I can feel the bottom of the blower and it feels like something like current or something. I don't really know how to explain it. Also when I push in the air condition button the light does not come on. I don't know if its related or not. Any help would be appreciated.

The first thing you have to do is test for both power and ground at the motor. Which one is missing, if any will determine where you go next.

OK, the feed for the relay comes from a 30A fusible link in the engine compartment fuse box. The trigger power for the relay comes from fuse #10 in the instrument panel fuse box.

The number 10 fuse. Is that under the dash. The reason why I'm asking is there is nothing pertaining to the heater under the dash.

Ok I've check the fuses and the fusible link. I am not getting any power to the fusible 30A link. So what does that mean?

I don't know how you cannot have power at at least one side of the fusible link. It is fed by the 100A fusible link for the alternator, right at the fuse box. If it's only one side of the link that has no power, then the link is burnt out. If you really have no power at either end, you must have a problem with the fuse box itself.

Okay, Could that 100A fuse make the alternator seem like its bad. Because today the battery light was on. So I took the hot post off the battery and the car died.

Please don't do that. That is the fastest way to fry every computer in your car. Yes, that is the link between your battery and the alternator.

Well, my next question is. Would my car still start if that 100A fusible link is bad.

Probably not, the 100 amp fuse feeds any computer driven devices such as the PCM and BCM of the car.
