Question about Hyundai Motor 2003 Sonata

1 Answer

Blower fan does not work on low or medium only on high. Lx model has auto climate control. wondering if it is blower motor, blower resister, or control (bad contacts). All buttons work on climate control. you can see fan blades go from 1-2-3-4 on digital control but fan only runs on high. If climate control unit do you need to replace the whole unit

Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.

Could a defective alternator cause fan motor to malfunction on Jeep cherokee?


What I can tell you is an Alternator can produce dirty electricity besides low or high voltage if the embedded regulator malfunctions. How "high tech" your fan motor is probably depends on the fan blower motor resistor. Advanced Climate Control goes beyond the simple setting for low, medium, or high. You can have a good Alternator and blower fan and be the victim of a bad blower fan resistor.

You can get your Alternator checked for free at Autozone, Advance, or Oreilys and it can be checked without removing it from the vehicle.

Fan control switch only works on high


If you blower fan will only work on high know that most blower motors are power by a basic electrical circuit that utilizes a multi resistor or a solid-state resistor to control different fan speed modes (low, medium low, medium and high). If the resistor malfunctions it may lose one or more of the lower fan speed settings. First check the fuse and change if needed. If that doesn't fix things change the resister.------------------------------------------------------------------------------------

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

The fan in my 2002 GMC Savana cargo van doesn't work. I lost low, then medium speed, and finally the high speed.I checked the fuses and relays.I changed the blower resister, still no fan. The heat


Hi Jim, If the vehicle is fitted with climate control it will have electronic management. However it can be wired by someone knowing electrical circuitry to by pass the control. It will save you some cash but will need manual control. Make sure whoever does the job knows what he or she is doing. Have a happy new year. Regards John

My fan for the Ac and heater will not work. iam trying to replace the blower resister


the blower resistor is in the plenum... above the heater core.
If the blower motor does not work at all ... you may have a bad climate control switch.... or blown fuse even... as the resistor is a two stage coil... Low speed and medium speed... no resistor on High and would normally not go at the same time....
