Santa Fe (CM - 2007-12) :: 2011 Limited - HVAC Blower Doesn't Turn On From Time To Time
Jan 17, 2014
Over the past year we have been noticing that the HVAC blower doesn't turn on from time to time. All settings in the control panel seem normal and the fan speed is turned on. Most of the time everything is working normally, sometimes when the car starts the blower isn't working and then starts after a minute of driving. Sometimes I notice the blower isn't working and I turn up the fan speed and after a few clicks it starts working normally for the remainder of the drive. And then sometimes the blower doesn't ever start and I need to turn off and restart the car a few times. When the blower hasn't been working the a/c compressor has been turning on, something in the blower circuit is failing.
There are five possibilities:
The HVAC controller isn't telling the blower to turn on
The power relay isn't always working
There is a wiring or connection problem
The blower motor itself isn't working
The power mosfet is failing.
What needed to be replaced?

I have a 2007 Santa Fe Limited and recently the main AC blower has been cutting on and off for long periods of time. The rear blower has not had any issues and has always worked. The main blower cuts off randomly and stays off until I tap under the glove box and then it normally kicks back on. Recently that has stopped working and I need to figure out what the problem is. Having the AC on or off does not effect this issue.

Last oil change at the dealer (they're free) I informed the service desk of some knocking and grinding noises that are happening from time to time in the front end.. and fluid in the driveway.. they did the oil and said they saw nothing... so I have to go back next week for my last free oil change and before I made the appointment, I dropped in to see my regular mechanic.. steering rack is leaking on the passenger side and has been for a while as the fluid is down to the minimum line in the reservoir.
Made the appointment with the dealer, informed them about the noise again and fluid on the driveway.. again. Let's see what they say this time.

I'm trying to figure out what has failed on my 2008 Santa Fe.
After stopping at a gas station today, my right turn signal came on and stayed on. By this I mean that the right turn arrow on the dash is illuminated and both the front and rear right turn signal bulbs are illuminated. They are all on steady, not flashing. Moving the turn signal stalk/switch does nothing. They all stay on when the car is turned off and the key removed. I have to disconnect the battery to get them to shut off. I tried pulling the turn signal, hazard and cluster fuses in the dash, but they had no effect. The switch for headlamps/park lights has no effect on the right side bulbs.
The left turn signal works normally.
Also, it may be related to having unplugged the battery a couple of times, but now the CD player shows "initializing" and I can't use it. The am/fm stereo works normally.

I drive a 2011 Limited. Three out of the past four mornings the car has been reluctant to start. It is cold out, but not super cold. This morning it was 1C (34F).
When I turn the key, it cranks but does not fire. I Held the key for what felt like forever, but in reality it was probably only 6 seconds. I let go of the key, waited a few moments and then tried again. After the third try, it finally fired and ran normally. It didn't stutter or otherwise seem to have any problems.
At this point I went inside and found my basic scan tool. No codes were stored and the voltage was between 13.5v and 14.6v. After I drove to work, I turned it off. The voltage dropped to 12.1v. When I cranked it again at work, I saw the voltage drop to 9.5v for a second before it fired up and jumped to 13.5v, then 14.6v.
The car has the original battery. Could it be as simple as a battery? Oh, I Just remembered, when the car did start, the radio was off. Upon turning it on, it was reset to defaults. Other than this starting issue that has only recently started, pun intended, and the radio I am having no other issues with the car.

The headlight beam height can be adjusted from inside the car. But even when not fiddling with the dial, I hear an electric motor sounding noise from them time to time, just a short <1s whirring sound. I listen with the bonnet open and I'm pretty sure it's coming from the headlights. Is this normal? is there any way I can stop it?

I have a problem that's sprung up all of a sudden and I wanted to run it by you before taking it in to VW. For the past three days or so the blower on my Phaeton's HVAC has been unresponsive to my control, staying on its highest setting permanently, even when I turn off the car.
This of course means that overnight power management takes over and when I get to the car in the morning I have to unlock it with the physical key, the clock has to be reset and I get all kinds of warnings about level fault and system fault. These warnings go away immediately as the car powers up, and everything is back to normal except for the fan.
I've tried resetting all settings on the control unit, but since the fan stays on even when the car is off, I feel like it's not software? The rest of the HVAC settings seem to work fine- I can toggle the vents and change the temperature, just not the blower speed.

I'm new and have recently bought my first X. its a 2001 XLT with the 5.4. I really couldn't pass it up with the guy asking under 7K with 104,000 miles and not a rust bucket.
I discovered last night that my blower (at least front) continues to blow when key is out and off. I have played with the key to think its a switch but am not sure. Here's the other part, If I turn the selector to off before shutting the truck off it stays off BUT if i turn it on it will not go back off and stays on....

I am having this issue if it's one. With the fuel level below last quarter, I'm having the time of starting the engine longer (cranking time). I tried several times, leaving the fuel level reach the last quarter, with same result. Reaching that level of fuel the problem appears.
Another issue is that sometimes when the day is hot and the fuel level is not necessary below quarter, the starting time is longer too. It's a Santa Fe AWD 2.4L Automatic.

I have a 2007 Santa Fe 3.3L v6 and the right brake light doesn't work all the time. When the vehicle is parked ignition on motor off the light works. Yet when driving I have been told my right brake light is out. I read that the turn signal switch assembly could be the problem.

I have a 2008 Santa Fe SE 4 cylinder that has been steadily losing gas mileage over the past few years. I had the fuel injectors cleaned a couple years ago but that did not work. When I bought it (used) in 2010, it was getting 22 mpg. It's now down to 17 mpg. The dealer recommends replacing the fuel filter (& lots of other parts). The car has just under 66,000 miles on it.
I did a search and also read through the fuel mileage thread that's on another Hyundai model forum, but nothing there addressed the slow, steady decrease, although I could have missed something .
There's no stalling, hesitation, slow acceleration, or other weirdness with the car otherwise. Driving habits and routes have not changed, although I might be driving a little slower than 5 years ago. I've had the codes dumped multiple times, with nothing showing up.

I have 3000 songs in folders on a USB stick. I understand how to get random play both within the folder, and for the entire USB. (Pushing and holding the button) What my frustration is is that everytime i take a phone call, or everytime i turn off the car, the random setting gets erased and it is back to sequential play. Is there a way to get this to a default permanent setting of "all random".

I have a 2007 Hyundai Santa Fe and over the last 3 weeks I have been having a lot of trouble with my door locks. One thing is my automatic lock that happens when you hit 14mph, every time I hit 14mph my doors sound like they are locking 4 times, and every time I stop and take off again they sound like they are locking 4 more times. It is driving me crazy. Another issue I am having is my back passenger side door doesn't always unlock with the FOB or the button on the driver door, it has to manually be unlocked.

My 2012 Santa Fe AWD Limited whines, all the time, from the time I start it until the time I shut it off. It gets louder with acceleration. What is that?

I am suddenly having difficulty starting my car. It will consistently turn over, but sounds as if it's running down the battery - right away, I don't sit for more than a few seconds with the ignition switch engaged. I turn the key to the off position and try again and it will has started up by the 3rd try every time so far. Once it starts, it runs great - no problems what so ever.
I replaced the battery about a month and a half ago so I suspected that perhaps I got a bad battery. I took the car by autozone to have them test the battery and alternator - both tested "good," But I should note that this was actually the second time I took it to autozone this weekend and the battery tested good but low charge the first time (It was fully charged this time and I had just had trouble cranking. I thought I had just killed the battery because I was using a cell phone battery charge and thought it was just drawing too much).
I suspected the starter may be going bad, but I'm not sure because it will turn the engine over every time, it just doesn't start. The girl at autozone suggested it may be the voltage regulator but I thought that that along with issues with the alternator itself would be noticeable if I ran the car with the lights, radio, etc on? I read that it could be the plugs or wires, but I would think in that case the battery wouldn't sound as if it were run down right off the bat.

I notice a bad smell when I start my 2011 ES350for a short period of time. After that it is fine. Auto has just over 10,000 miles on it. E mail from dealer tells me filter needs changing. Somehow I believe there is more to it.

My 2010 SF has 36000 km and I've noticed a "crunching" type sound every time I go over a steep ramp or a speed bump. The sound comes from the rear and never happens on smooth road. I took the car in for service last week and the dealership has ordered two rear replacement shocks -- they say it's premature failure.

I have a chevrolet optra 2007 and the hazard lights won't work unless the turn signal (left or right) is switched on at the same time. Turn signals work perfectly fine.

2006 Subaru Outback
I am driving along and my radio go silent. the AC & the blower go out at the same time. I drop off the car in to the Subaru dealer in Steamboat Springs, Colorado. they call me back in a couple of hours and tell me I have bad radio that might work for a while longer but they recommend replacing it. $350 plus tax & labor.
I get the car back and the scan button no longer works & the buttons stick. does this seem right?

2004 Prius, 135,000 miles.
About a month ago, the blower motor stopped coming on all the time. A quick whack under the glove box fixed it when it didn't start. Then about a week after that, I felt like the AC wasn't really warming when needed. This may have been true earlier, but it hasn't been that cold around here, so I wouldn't have noticed, perhaps.
About a week ago, I start hearing what I might describe as a rattling kind of noise I had never heard before sometimes under hard acceleration. Not always. Didn't hear the noise tonight, for example. Of course, then, tonight, on the interstate, the warning light pops up for just long enough for the temperature indicator to flash up. It quickly disappeared, but in the remaining two minutes I was driving, it flashed up briefly twice more.
Now, in digging around on this topic, I've read about issues with the inverter coolant pump, and that there was a recall. How could I find some information on this recall? I don't remember ever having it changed, so I'm just curious what I might need to say to get that swapped out under a recall if appropriate.
Also, based on what I've said, does it seem likely that the issue is with that pump? It sure seems to fit the bill, but who knows. I'll be bringing the car in ASAP but I'd naturally like to be armed with as much information as possible.
