Sonata NF (2006-10) :: 2007 - Cooling Fan Always Running When Key On
Mar 4, 2015
I'm working on 07sonata 2.4. The cooling fan is always on when key is on. I used to be a hyundai tech and remembered seeing something about the engine room fuse box and I have access to wiring diagrams. So in essence you go to connector jc01 pin 2 pink and connector je01 pin 25 pink. Cut the wires and connect them together bypassing the fusebox all together. But that didn't work this time. One thing I discovered is that if I touch my power probe to the heatsink of the fan control module I have battery voltage available. I first discovered this because I was removing said module and my 10mm touched it when it slipped a touch.
Is this 'hot' heatsink evidence of a shorted module? No codes in system. Ect tests good when hot and cold. A/c is not commanded on. Being that I used to be a tech for Hyundai I also know the engine fuse box can be touchy as well...

2nd time happening to me: I started my car, backed up and drove few hundred feet before stopping at a traffic light.
While stopping there, I noticed the engine cooling fan was running at max and the temperature was going rapidly up (in less than 10sec the gauge almost hit the red line).
While the gauge was going up I shifted the gear stick to P and the gauge dropped to normal in less than 5sec.
I shifted back to D and the car drove normally ever since.

I have a 2007 Sonata and It recently lt began to blow hot air out of one side and freezing cold out the other side. Took it to the dealer and the technician said he didn't know what was wrong but recommended that the system be evacuated and refilled at a cost of 281.00. Actually, what he said is that the compressor is either overfilled or underfilled.

Was just on a trip (about 200 miles or so each way) and the AC worked just fine.
Car has sat for a few days unused.....when I used it to day, the AC blows warm...doesnt cool at all.
I hooked up a gauge to the low pressure side and the pressure reads very high (in the red zone of the gauge).....
Cant tell if the compressor is kicking on or not when the car is running...
Car is 600 miles out of warranty (of course).

I notice a high pitch squeal when I turn off the car ignition and is synced with the slowing of the engine cooling fan. I don't notice any significant engine noise while the car is fully running in idle. Does this indicate that bearings are going bad in the electric engine fan assembly? If so, would the noise alone be justification for getting a warranty replacement by the dealer or would they need a total fan failure in order to get it replaced under warranty at no cost. If not, think its worthwhile to replace the fan module myself to avoid imminent failure?

I understand that filling up with gas when the car is running is not recommended. I did it once without realizing that it could cause issues. Now I am trying to determine if that action has anything to do with the CEL being on. The codes are P0442 and P0456. The codes have been cleared several times but the light pops back on after a while, anyway from one day to a week later.
Smoke test did not reveal any issues. My question is this, can filling up with the engine running cause any physical problems with any of the EVAP components? What would be the most likely problem? I plan on buying a new gas cap, since it is cheap. I do not wish to spend a lot fixing this problem.

I often make 25-30 quick drop off stops on my daily travels and need How to lock the doors with the car running as that many stops and starts will wear out my starter and be really hard on the car.
I know it is possible for the doors to lock while the engine is running as my car came with an aftermarket (pro start) remote starter. It will actually lock the door when it starts the engine, which is inherently useless as my car is always locked when I start it (from the the house) before I get dressed to go outside in cold weatheras well as I am not worried about someone driving away in it without the key to start.
In my old car (mazda) I could just keep the FOB in my pocket and lock the doors either manually or by the FOB when I got out. My Sonata wont even lock by the the FOB which is really frustrating because obviously in that case I am leaving the car running and want to lock the doors, IE: to warm up the car. I can understand why the door locks are disabled with the key in to prevent lockouts but if you need to warm up your car or Like me need to lock it while I am gone for less than a min.

I'm facing a bit of a problem on my girlfriends dads 2009 Sonata (Non-Premium sound system). I just installed a Pioneer aftermarket head unit and am getting no sound when the car is started or when its in ACC mode. However, when the ignition is just turned to the "ON" position (first click) the head unit works flawlessly and all 4 speakers output sound. As soon as I turn it to ACC or start the car, there is no sound at all but the head unit still powers up and shows the track playing. I'm really stumped here guys. I've done literally countless head unit installations and I just can't figure this one out, nor have I ever seen this before. I thought the problem might have been a factory amp, but the head unit does not say JBL or Infinity so that leads me to believe it doesn't have a factory amp. Maybe I'm not the pro I though I was lol.
At any rate, just in-case it matters, there is a line out converter attached to the system in order to add a sub/amp to the stock head unit that I installed a few years prior to attempting the aftermarket head unit installation. I don't think that would matter but I may be wrong. I was planning to remove it and route the RCA's to the aftermarket head unit once everything was up and running.

Is there any chance to remove the Day Time Running lights, connect and LED strip and still use the parking brake functionality and have it automatically switch to the low lights (HID) and still use the LED strip?

When I'm driving and get above 50-60 I will get the Check Engine Light. Check the codes It shows 6 ---300, 303, 306, 300, 303, 306. When I slow the car down it is running rough, almost like it has a miss.
I reset the computer while this is going on and the engine smooths out and it runs correctly until I keep my pedal down and then it kicks the exact same errors.
Here's strange part number one: Once I get down to about a gallon or two of gas in the car everything seems to run fine. I have plenty of power, no codes and the car runs fantastic!
Strange part number 2: Very occasionally When I get in the car in the morning to go to work, the car is a bit difficult to start. When it finally kicks over, it is immediately running rough. resetting the computer with the engine running does not seem to stop the rough running. If I turn off the engine and let the car set for a bit it will start and run fine, with the exception of the first problem mentioned in this thread. There is no code while it is running rough, but when the Light kicks on as per the first issue mentioned, I have an additional code -- 335. This car has been excellent up until the last few months when this issue developed.

My 2.4L engine is making a clanking noise while running. When I checked the oil level today, it was low by about 1.5 quarts. There's no check engine light.
Car has 74K miles now. I purchased the car two years ago with 35K miles. I have always performed regular maintenance myself. The car had its oil control valve replaced at 55K miles.

I have a 2009 4cyl GLS with a manual trans (about 18K miles). For the past few months, I have been noticing a faint gasoline odor both in my car and around my car after it has been running for awhile. And yes I have checked and it is not on my shoes or floor mats. The car does not smell until I get off the interstate etc... At first I thought it was another car around me that is giving off the odor but after many trips without cars near me, I can smell it and my passengers notice it too. It does not seem to happen when it is full, usually only around a half tank or less. I checked all around and under the car for any signs of leaks and found none, just wafts of gasoline odor. My MPGs is not off so I must not be leaking too much but the odor is getting worse.

Here is a video of my sonata exhaust running rich and "popping" when i ease off the gas when in P/N (haven't driven it enough to recreate it on the street in gear). I also included a teaser pic of my plasti dip project which is almost done and ready for me to enter the Ride Of The Year.

Yesterday, I had to accelerate really really fast...ever since then, my fan does not turn off (when the car starts). I just started the car cold and it is running. I think the fan relay has gone out. I'm not sure which fan exactly...but when I opened the hood, I see that the fan behind the radiator is the one that is spinning.
Where is the relay for the fan is in the main junction box under the hood (near the front left strut)? Can I put the relay out (by hand) while the car is running? Can I also drive to work for a day or so with the fan on while I wait for a fan relay?

My 05 V8 Phaeton radiator cooling fan is not running and hence engine overheats. The AC cooling fan works alright, it comes on when i switch on the AC. I have verified that the actual radiator cooling fan works by plugging it to the ac cooling fan socket. I have checked fuses and all ok. there are no dealers near me. I have also gone through all the cooling fan threads and all of them are for constant running fans, none for a non running fan.

03 Santa Fe, 2.7 L engine. No cooling happening. Compressor not running. Jumpered both sides of the triple pressure switch. Jumpering Low/high side resulted in slight increase in engine rpm, Jumpering medium side and something turned on (didn't get a chance to investigate) but still no clutch operation on compressor. Wondering what to try next other than disconnecting and dropping compressor ?? Checked AC relay on the bench and the coil operates and contacts close, so that's good. Also10A fuse before relay contacts is OK.

I noticed that in some cars (even new ones) the cooling fan stays on for a minute or two, even after the engine has been turned off and the key removed.
This caused me a little bit of curiosity —keep in mind I'm not very car-savvy— so I wanted to ask: Why is that?

Went outside to start my '99 V6 and nothing! No interior lights, no door chime, no annoying ding ding with the key in the ignition. The car ran great yesterday but I noticed it sounded like the cooling fan was running long after the car was turned off in my garage.
I tried using a car starter/charger and charged it up for 3 hours - was reading a positive charge on the gauge- but it won't start. When I get ready to crank the car with the charger attached to it, the fan noise kicks in again but it isn't coming from the radiator fan- it sounds like it is coming from under the air intake for the air filter.
When I attempt to start the car,I can best describe the sound as a machine gun like cranking noise that lasts as long as I turn the key. I am hoping it isn't the starter. The battery is less than 2 years old with about 10k miles on it.

My Lincoln engine / coolant fan is running high about 90% of the time but the car is not overheating or heating up prior to the fan issue. This is a new situation. I'm trying to avoid a $1200.00 new fan purchase ( it only comes as a one unit option - fan, shroud, motor ).
