2017 Hyundai sonata fan blower only works on level 4. level one two and three do not respond. the resistor controlling the fan blower has failed. follow me while I troubleshoot this issue.
Dude, you are the man! My resistor had the exact same gap; soldered it down, just as ugly and now it works great. Thank you! you saved me some money with this fix.
Yeah, I don't think I would've soldered that. Most devices like that is designed with a safety feature to pop when it's senses excessive heat with the part so it won't damage something or cause a fire. Kind of like the thermostats on your dryer.
@timfromthe618 Normally this is the function of the fuse. Based on what I could see, either the resistor had some water leak on it or the motor is drawing too much current because it's worn (bearing or brushes).
The high setting for the fan bypasses the blower motor resistor. So if you don't get ANY blowing air on the highest fan setting, it isn't the blower motor resistor. It's probably the fan motor, it's harness, or a fuse/relay.
@@sponation mine doesn’t work at all , the buttons don’t even press , I changed the whole panel , worked for few weeks , and then the same problem happened , I changed the fan and the fuses , nothing helped, and the , and I only have hot air , everything in the car the good , just the panel always have the same problem
I'm not sure but I do have a screwdriver with a flex head so it will bend around corners. It's possible I use that attachment to get in a tight space. A short stubby screwdriver might also get in there.
That gap isn't a flaw. It is an intentional feature that pops off the solder when the resistor is radiating too much heat. Yes, you CAN resolder it and it will work OK. But it indicates internal corrosion between the plates and poor efficiency. A new one costs $20. Just replace it. It says to replace it when the fuse breaks ON THE PART in large embossed letters both in English and Korean. The fuse it is referring to is that springy piece of metal that pops off the solder on purpose. It's a crude, but effective type of thermal fuse. Think about it. Why would the metal not be bent to make contact without solder? Why have a solder connection there at all? Wouldn't a small wire be more durable instead of a springy piece of metal? It's made to NOT be durable so it blows when the amps (and thus heat) gets too high. THAT SAID, I did resolder mine so I would have ac for the three days it took to get the replacement shipped to me. But I didn't fix it. Resoldering it is equivalent to using a paperclip to bridge the gap between conductors when a fuse blows. It's not a safe solution and probably will eventually fail again. You might want to take some fine sand paper to remove any obvious surface corrosion from the plates. But the corrosion forms between them regardless.
Exact same car, exact same problem, about to try the exact same thing, thanks 👍👍
It worked, thanks for the help 🙏
That's awesome I'm glad I could help

Awesome glad I could help
Worked great for my car much appreciated
Thanks for the video. My resistor had the exact same gap; soldered it down and now it works great. Thanks!
Awesome glad I could help
Thanks, my sister's car has the same issue and this may help us! Much appreciated.
Glad to help
Thanks brother, got this issue in my 15 Elantra. Gonna have to fix it soon
Glad I could help
tks i did the same and results is perfect. keep going with yours videos.
Thanks, glad I could help
Saved some money thanks
Glad what helped me helped you!
My man!!!!!! I just fixed the problem! You are fucking awesome man!
Awesome glad I could help!
Good job

You could certainly just replace the part👍

I have a 2016 sonata and the blower isnt working at all. I wonder if this is the issue since I still get warm air when the heater is on....
If your fan is not working at all I would check the fuses first and then try replacing the fan itself.
The high setting for the fan bypasses the blower motor resistor. So if you don't get ANY blowing air on the highest fan setting, it isn't the blower motor resistor. It's probably the fan motor, it's harness, or a fuse/relay.

Mine works on all settings sometimes but will slowly die down within a min to a super soft blow. Same car!
Help please!!
Might be a bad blower fan
what screw driver did you use? i can't reach mine
