Elantra HD (2006-10) :: 2008 - Heat / AC Blower Intermittently Not Working
Jan 4, 2015
I have a 2008 Elantra w/ 108K miles. The current issue is the heat/ac blower intermittently not working. On Christmas Eve I started to drive it and realized the windshield was fogged up because blower was not working. The next day it worked fine...we chalked it up to maybe being related to having plugged a crock pot into the cigarette lighter (with a plug convertor thing)...wishful thinking that maybe something just got "overloaded." It has been working fine since, except last night when I started it, same thing--no air blowing on any of the settings (I read that if setting 4 works, but not 1-3, it makes a difference w/ the diagnosis). And, then again today...it works fine. Other things that I have noticed/that have happened in the past year or so (possibly unrelated, but figured it couldn't hurt to mention them just in case):
June 2013--started intermittently hearing a loud buzzing type sound (at first thought it was my phone vibrating)...sometimes would happen randomly, but mostly when I would adjust the heat/ac...sound coming from the passenger side front of the car floor area (maybe under glove box where I know the blower motor is). The buzzing would last anywhere from 2-20 seconds. Never did anything about it since everything was working fine...
Last winter--while driving home during a heavy snow storm w/ defrost on high and windshield wipers going noticed that the fan/blower seemed to "surge" when I stepped on the gas..like the blower would slow down when I braked and blast out much more air louder when I accelerated. I noticed this again tonight...possibly it has been ongoing and I just have not noticed.
Early Dec 2014-present--unable to adjust the temp setting...despite twisting the knob from red to blue, it remained hot air. Assumed it's the blend door, but figured we'd deal w/ it in the spring when I needed cold air again!
What this could be (or an overall problem that would explain all the problems?).

I have a 2008 Prius. The blower for the AC and heat stopped working. I have checked the two AC fuses and they are okay. I used the touch screen diagnostics mode on the touch screen and it appears that the touch screen and the screen switches are working. Any other things to check?
How hard is it to access the blower motor to replace or to check if it is getting power? How much of the dash has to be disassembled?

Over the last half of the summer my A/C stopped working on three separate occasions. Surprisingly none during the day (~100 at the time) all happened at night. I would drive somewhere with the A/C on with no issue, however when I would get back in my car 5-30 minutes later nothing would come on. The A/C and recirculate light would come on as usual, but no air at all from the vents. I tried restarting the car, checked the fuses, nothing. Then maybe an hour or two later it would come back on. So far this has happened 4 times, with the most recent being a week ago. I took it to a dealer when it first started happening and they could not find anything out of the ordinary. The last time it happened, I drove straight to the dealer, only to have my A/C come on 50 ft from the dealer. Another odd symptom I have seen is when I switch the A/C to the off position occasionally it will come back on for two seconds and shut off. (electrical maybe?) At fan speed two it makes a quiet ticking noise that it didn't make when I first bought the car (though my '01 Accent made the same noise).

My 2006 F150 was purchased by me in early 2009 with about 28,000 miles on it. It's an XLT crew cab 4X4 with the 5.4. Stock except for a leveling kit and an aftermarket head unit. It currently has about 59,000 miles and has been babied since I purchased it. About 3 years ago I started noting some issues:
A. Oil pressure dummy gauge is all over the place. Some times it will show no oil pressure. Other times it is all the way to the highest mark. Other times the needle has gone 180 degrees past where normal is and is actualy pointing straight down towards the floor.
B. Recently my alternator dummy gauge has started doing the same thing as my oil pressure gauge.
C. The backlight behind my odometer works intermittently, but mostly not at all.
D. My dome light will flicker when first turned on. It doesn't matter which door is opened or if the override switch it turned on. It takes several seconds to come on and will flicker like there is a poor connection somewhere, but stays on once its on.
E. Blower fan will occasionally stop blowing. Once the climate control switch is turned to off, then back to on it resumes working. This doesn't happen often, but does occasionally.
Fortunately, the truck has not left me stranded and I want to keep it that way. We are getting ready to sale my wife's Toyota and this will become her daily driver. I want to take care of any issues before she starts driving it. Are these all separate issues or is there one common issue which could be causing them all?

Got a 2008 Hyundai Accent. Yesterday, the blower motor just stopped working. I had just started it up, the heater came on for about five seconds. There was no noise, no funny smell, nobody had done anything to it. It just stopped. I checked the ac fuse and it looked fine. I looked in the fuse box under the hood, and I'd like to check the fusible link for the blower motor to see if it has a problem. Is this something I could do and how? Also is there anything else I can do to diagnose the cause of the problem?

My 2007 Prius has stopped producing cabin heat; the blower fan is working. I have no dash warning indicators. I am in an area where the are no Toyota dealers and need to drive 160 miles to home and shop. It has just turned cold. Why and if I am ok to drive to the shop?

Stock FM/CD/SAT radio that came with my Sonata, AM stopped working intermittently while FM and XM both still worked. Upgraded the radio to JVC with Bluetooth and found that AM still does not work. FM works fine as well as all other functions.

A few weeks ago my battery died and I had to jump start my car. After the jump start, my heat wasn't working - no air will blow out on heat or A/C. I checked the fuses - all good.
I pulled the blower motor out and tested it and it worked hooked up to a battery. At one point when the blower motor was still in the car I banged it with a hammer and it turned on momentarily then shut off again.
Since the blower motor seemed to work outside of the car, I assumed it was the resistor that was bad. Replaced , and still no heat.
Could the blower motor be bad and just have worked hooked to a battery intermittently?
What else could it be?

2003 F150 4wd with auto climate control. My blower for heat and AC completely stopped working a few weeks ago. I have checked all fuses, i replaced the relay under the dash, i replaced the blower motor control module. I supplied power to the blower motor itself and it ran fine with no noises. I ran the self test on the controller in the dash under the radio and it passed. I am not sure what else to try.

I have had this car for about a year now, no problems other than the check engine light has come on and after a code check found out its the Cat converter *yay*.
Most recently the A/C blower is working rather intermittent, can start off blowing just fine and then the blower seems to decrease while the screen still shows it on high. AC temp is just fine, just the blower is having issues. Sometimes it will turn off all together and not come back on at all for several hours. I am thinking it might be the fan motor, but I don't know enough about these cars to say for certain.

I have a 2008 Elantra Sedan Limited. The far right control knob for the direction of airflow does not work anymore. A few months back int would make a short strange noise when switching from the feet or head to defrost, etc. Then is stopped working last month and now it only blows air to the head area. Is there a cheap way to fix this? My brother who is a parts manager at a Ford dealer says it is most likely a faulty switch inside and a dealer only item.

My 2004 camry LE (235K miles) has had a noise associated with the blower for several months. The blower worked fine on all settings but had a subtle noise that was between a purr and a click. It's constant, fast-paced, rhythmic and rises in pitch as the blower setting is changed. Hot or cold settings don't make a difference. The closest I can approximate is the sound made when kids put (or used to put) playing cards in the spokes of their bikes.
However in the last couple months the blower has stopped working intermittently. Sometimes it will come back on if I went over some railroad tracks or a hard bump. If I turn the car off the blower may not work when it's restarted. The last couple days it's stopped doing even that, and since there's snow on the ground it has become an issue! The fan setting doesn't make a difference, high or low.

Push A/C button is always on green. The (air speed) 01234 button is also always on green. the Push button turns on and off orange whenever I click it.
Anyways, the AC doesn't blow any hot air... always just cold. I've adjusted the dial to red and have left it there for a long time... no hot air. Any trouble shooting I can 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.

My Blower motor is intermittently going on and off. After messing with it for a while it seems to stay on. Motor may be going out. Not real easy to change the blower motor on this 2008. Haynes manual says to take the 2008 and up trucks to the dealer.

My wife has a 06 Sonata with the Manual AC controls. The blower motor works intermittently. Sometimes it works, other times it does not. It does not matter which setting the HVAC is in. Yesterday while driving it, we went over a bump in the road and the motor started running again. Since the motor runs, I want to discount the fuse and relay.

Blower motor has stopped working on my 2008 jetta 2.0. Motor works fine and I have traced the issue back to the fan switch connector which is not getting power. Seems like it should be a fuse issue, but they all seem to check out fine. Not sure where else to look. Is there a relay upstream that could be bad? I have owned since new and it has never been apart.

AC blower isn't worked, I traced it back to the AC dash control panel (switch).
How to remove just the AC control panel/bezel? I see no screws or anyway to snap it out.

Car: 2007 Sonata 2.4L
I hadn't used my car for like 3 weeks until yesterday when I drove back to PA from MA. I turned the car on, a/c on and went for a nice 6 hour drive. About 2 hours in (with a/c working) I stopped for a break. The a/c blower would not turn on at that point. I could hear the compressor clicking on (and the RPMs would respond appropriately). I tried turning it off and on a couple of times but no go. I decided to keep on driving and figure it out when I got home.
About hour 5 I turned the knob from OFF to Max A/C and it turned on! It worked fine all the way home. I drove the car a couple of more times last night with no A/C issues at all. Well today the same thing happened. Went to go drive and no a/c blower. Compressor still turning on. I changed the only fuse/relay I could find that was dedicated to the blower inside the engine compartment (40A) with no luck. Am I missing any other important fuses?
Being that it intermittently works I'm thinking something might be lose or some electrical connection.
