Santa FE SM (2001-06) :: 2005 - Heater Blower Runs Continuously
Feb 14, 2011
I have a 2005 Hyundai Santa Fe 3.5 litre 4wd and am having a crazy problem. It has the automatic heating and air conditioning module (digital). The heater fan comes on as soon as i start the engine and runs in the 2nd highest speed. I can adjust it so it goes one speed higher but never lower than the one it comes on at and cannot shut it off. It operates the same under heat OR A/C modes. The temperatures adjust o.k. but it is always on. Where would i find the a/c control module? Could it be the transistor or resistor and where are they located?

How hard is it to change the A/C/Heater blower motor. I know about the switch problems but this is the blower motor. I'll probably clean it out and spray something in it before I replace it but I just wondered how hard it is to get to. On another note, this 4 wheel drive Santa Fe rocks in the snow! I can't believe what good traction it has!

The heater blower in my 1999 F350 continues to run after the switch is turned off. I checked the relay and it is working properly. Looking for a wiring diagram showing the control circuit for the blower?
Do the heater switch controls power to the relay coil or if the switch grounds the coil to pick up the relay?

My 2009 Santa Fe GLS a/c, heater, etc. blower has stopped blowing air. I have checked the fuses, did the push test on the air adjustment button but nothing has worked. Sometimes it's like I can feel a VERY SMALL amount of air blowing out the vents.

I have a 2005 Dodge Caravan with a heater blower that doesn't seem to be working. Whether the heater knob is on low or high, it does nothing, but you can feel a little heat coming out, though. I was told it may be a resistor behind the glove box. I've already checked the fuse, and it seems OK. What do I do?

I have a 2004 Elantra. The blower for heat/ac not working. I did all of this:
Checked interior fuses, all OK.
Checked 30 amp fuse in engine compartment, put a new one in.
Pulled blower motor out and tested with a 12V power supply: worked fine.
Replaced Blower Relay
Replaced Blower Resistor
all of this and still no blower.
The heater control panel on the dash has 3 knobs. When I turn the first to AC...the light comes on and I hear the AC kick in. 2nd knob is blower fan...nothing on any setting. 3rd knob...hot and cold...not sure since no blower.
I am lost at what to do next.

The CD drive motor has started to run continuously. Nothing will make it stop, other than shutting down the whole car, and even then it runs for a while longer. Is there a fuze somewhere that I can pull? My guess is that the CD player (which still works) would have to be replaced and that doing that is several hundred dollars. Our Prius is 2006.

The car is a '99 Volvo V70 XC AWD. The blower for the heater wasn't working this morning. When I left work it was blowing a little but not as high as it should on full.

I replaced the blower relay around this time last year. I noticed this morning idling that the vents weren't blowing then when i was moving i heard it tick back on and would blow normally. This happens when driving too but more noticeable when idling. The AC light also flickers and goes on/off.
I can go ahead and replace it again but this seems to have gone through this brand new relay pretty fast. What I can fix to stop going through relays?

I have strange issue with my a/c fan, its running continues even will the a/c switch is off.
I cant stop it. So I have to remove the fuse to stop it. My ac panel is automatic.

Today i had my ac running and switched the speed from 3 down to 1, then poof totally went off and will not come back on at all. I tried replacing the resistor, still nothing. Next tried the blower motor, still nothing. Then replaced all the fuses, still nothing. The compressor is kicking on. Can here the click under the passengers side when turning ac on, but the blower motor is not coming on.

2005 Santa Fe - 3.5L w/ Auto a/c controls (it matters for price on the resistor. boo!)
I find myself having a really hard time sliding the motor back in. It was difficult to pull out before and now it's nearly impossible to put back in.
The Fan wheel measures 5 3/4"
I believe the issue has to do with prefab installation and a very large wheel causing this to be too difficult to push in at an angle.
I see different dimensions for fan wheels and I'm thinking that may be the key.
I already have to replace the blower motor.

I have an 02 Santa Fe and last night while driving the fan would not turn off. It also started switching speed by itself.

Blower only works on high speed. From what I have read the problem is either the switch or the motor resistor. I am leaning toward the resistor which is behind the glove box. Where can I find directions for removing the Glove box?

Often, when starting it will run rough and throw different misfire codes. Most of the time it smooths out in short order (a minute or less). When it doesn't smooth out quickly, it smooths out when I clear the code. Also, rarely it will start very hard. I have to wimd out the starter pretty good to get it to start. All that I have done is cleaned the MAF sensor.

I have an 02 2.4 gas SF. After a good while, the car will run rough, lose power and will not take any throttle. As if it is starving for fuel. But it will idle fine and if it does stall, will restart. On a hill, I have to drop into first and keep it at 1000 RPM (yikes!)
If I keep going with very little throttle, it may resolve itself. It is always fine after a complete cool down. I checked for vacuum in the tank by opening the filler while it was misbehaving. I have a new CPS, new coil packs, new filters. I've have enough gas fill ups to eliminate water in the gas.
It has thrown no codes. I went ahead and ordered a MAF sensor and a cam position sensor...just guessing. (it had failed emissions which I resolved by cleaning the MAF.)

I replaced blower switch last year a couple of years ago. I recently starting to get clicking noise from blower relay, and fan turns off then comes back on.
Question:
1- Problem more likely to be from the relay or the fan switch? Should I just replace the relay?
2- I can see and touch the fan relay, but how do I get to it to replace it? What dis-assembly is required?

I have an 04 Hyundai Santa Fe 3.5L V6 AWD with climate control. All other trucks this year I've only seen with manual HVAC controls. My blower motor is constantly running anytime the key is turned on. It feels like it is blowing 3/4 strong all the time and I can turn it up, what feels like one setting higher. Even if the climate control is turned off it keeps blowing. I can control the temp and AC and defroster, I just cannot control the actual airflow pressure from the vents. On an older car this seems like a resistor issue. Is this a common issue? If so, what can I do to try to rectify this?

My daughters 2005 Hyundai Elantra has 77,000 miles om it. Just changed the wires and plugs, new brakes. Now, it runs very rough when stopped at a light and it is in gear. Now, when she has the AC running, and she stops at a stoplight, she has to put it in neutral or the engine will almost but not quite kill.
