blower motor stopped blowing air

[boxer15]

I have a 98 sonata and the recently the blower motor was giving trouble trouble with bot the heat and the ac. It would run fine and you could the fan speed but sometimes it would just kick off and stop blowing air and would then randomly come back on. Well the last few weeks it kept cutting off more and more and now it has cut off and won't come back on. I do not know if it is the resistor or the actual blower going bad. Is there any way to check?

There are several ways to check them. Locate the resistor, then use an ohm meter to determine the resistance and continuity through it. Easiest way to check the fan motor is to locate the wires going into it, and see if you have the proper current going into it. If you do then it's probably a bad motor. However, if your fan motor sometimes just kicks off and sometimes comes back on, you may just have a bad connection somewhere or even a bad fan relay or fuse contacts. Fan motors will normally make noise, or start or run slowly, when they go bad. Resistors generally go out on 1 speed or some on anything above a certain speed, but high speed usually still works because it normally bypasses the resistor controls. So if it works on high even when the lower speeds don't, it's probably the resistor control. But if it just suddenly shuts off, and sometimes comes back on, it's probably a bad relay or connection somewhere. And it is fairly common on some vehicles for the connection at the resistor to go bad since that is where the load always goes through and varies the most, so it requires a good solid connection.

The blower switch is a common replacement on this vintage Sonata/Optima. It happened to me and a used switch made it all good again. If you're so inclined you can gain access to the connector that plugs into the switch and use a jumper to see if that's the problem. None of the parts being discussed here are inexpensive.

don't know if any of this will help, but just some info for you. my wife's car 2001 sonata had same problem. zeroed in on blower motor and it replaced it. 6 months later it happened again. blower motor again. what was happening was that she had an in cabin air filter and we did not know it and it was blocking the air flow so the blower motor was burning up! 6 months later my 2002 sonata started to do the same thing. replaced the blower motor (don't have in cabin air filter) and all was fine for a month. started to do it all again. now i looked at the switch and replaced it also. fine again for 3 weeks. now it's doing it again just as you stated. now i am just starting to looking at the blower relay. i am chasing the same problem and getting very frustrated about it. good luck, i'll let you know what i find out. if you look back in the forum you will find my posting on this issue! might help.
