Golf IV / Jetta IV :: Radiator Fans Are Unreliable
As it was such a matter of time, my fans on my 24v gave up during winter, no big deal as it was a pretty cold winter but now that spring is around the corner, I gotta fix this issue. To they change for the same OEM unit that will die in the next 30k miles.

View 19 RepliesGolf IV R32 :: CEL Code P2181 - Radiator Fans Do Not Turn On
So this seems to be a common code that is thrown when you near 100k miles, I'm at 77k .. This thread seems to be the most organized [URL] ....
"Long story short, there are 5 main reasons this problem can pop up, listed in order of likelihood, least to greatest:
1) Coolant sensor
2) Thermostat
3) Bad fans
4) Coolant mixture
5) Water pump "
My issue is that the only ones I'm (probably) able to rule out is coolant mixture and bad fans. My radiator fans do turn on from time to time, so I thought I'd ruled that out (unless it would throw a code for not turning on at appropriate times?)
I heard of a test to turn on your AC and see if they turn on, but my AC hasn't blown cold air like ever, so I don't know if that affects the test (probably not?)
A couple years ago I had a shop replace the original thermostat with the new one, or was it the coolant sensor, or both (ugh, I don't remember!) That leaves thermostat, coolant sensor, and water pump.
I guess my main question is is there anyway to find out which it is between these 3, without spending so time, money, parts etc? It doesn't seem the coolant sensor is easily accessible for one.
My car has been really slow recently but I also need to change the spark plugs, I'm doing that this week. I cleared the CEL/P2181 code and it returned a few weeks later,
I'm starting to change my mind about this car being easy to maintain/reliable, I'm always on time with maintenance and with only 77k miles on a 2004 car.
Elantra XD (2001-06) :: Radiator Fans Coming On More Frequently?
I bought my car last May and never noticed the radiator fans running, but over the past couple of months they've been coming on (or at least running at a higher speed) pretty much every time I take it for a longer drive. They appear to come on only when I'm idling and turn off when I start moving again. The temperature gauge is steady at just below halfway. I'm certain this didn't happen previously, or if it did the fans were at a low enough speed that I didn't hear them. In my inexperience I would have thought they'd be less likely to run in the winter, and we've been having continuously cold weather (<30 C).

View 13 RepliesPrius (Gen 2) :: 2006 - Radiator Cooling Fans Stopped Working
I own a 2006 Prius with 52k miles on it. Great car BTW. The problem is simple, the radiator cooling fans stopped working on high mode; they run around 25% only even, not removing the heat from the a/c evaporator and the radiator coolant. I checked fuses: OK, checked relays: OK. They spin freely and nothing is blocking the front face of the evaporator. Funny I noticed it when I started hearing the a/c compressor buzzing noise and then I realized the fan noise wasn't there!
View 7 RepliesGolf IV / Jetta IV :: Radiator Fans And AC Stopped Working At The Same Time
A few days ago I was driving around. I get back in my car and when i turn it on no air blows and the radiator fans aren't working at all. My car hasn't overheated but have stopped driving until I can figure the issue out. I have since replaced the fuse box on top of the battery to no avail. I was thinking that it could possibly be the fan control module but in all the posts I am reading not one says that theirs don't work, they just keep running. So is there something else i should be looking at?
View 1 RepliesGolf IV / Jetta IV :: GTI VR6 Fans On Radiator Don't Turn On / Engine Gets Warm
I'm having an issue with my fans on my radiator. They don't turn on when the engine gets warm and the A/C is off. I've replaced the crack pipe, water pump, and belt tensioner. I've replaced the fans not to long ago because the low speed wasn't working. I tested low speed at the fan connector and it wasn't working. After replacing fans I tested and it was working when jumping the pins on the thermo switch connector. I got both low and high speeds to work during that test. I've since replaced the thermo switch to see if it would fix the issue but the fans still won't come on without turning the A/C on. Any other tests I could do or should I just try to get another thermo switch.
View 4 RepliesFord - Flex :: 2009 - Radiator Cooling Fans Won't Working
My wife's 2009 Ford Flex has an intermittent radiator cooling fan issue. It has dual cooling fans and with the AC on, the passenger side fan runs wide open but the driver side fan doesn't run. With the AC off, neither fan runs even though I let the car idle for a long time to try and get it hot enough to allow the fan(s) to turn on. It doesn't matter if the engine is cold or warm, the passenger side fan runs extremely fast when the AC button is pushed. I've checked all connections and applied some dielectric grease to the connections. I also checked the fuses to the fans. Have to buy the entire dual fan assembly?
View 3 RepliesGolf IV / Jetta IV :: AC Will Not Activate Until Engine Gets Hot Enough That Radiator Fans Turn On
I have an odd problem. My AC will not activate until the engine gets hot enough that the radiator fans turn on. Once they do, the engine RPMs drop, the clutch kicks in, and I get frosty cold air with no problems. I already replaced my FCM and checked all fuses. It worked consistently all last summer and considering the AC is nice and cold once it kicks in, I don't think this is a pressure issue and it was recharged at the beginning of last summer by a good shop.
I changed my coolant flange a few months ago, same temp sensor. Didn't try AC back then as it was cool outside still. Could this have something to do with it? I have proper readout on my dash. Maybe it's the ambient temp sensor?

Golf IV / Jetta IV :: Both Radiator Fans Run All The Time While Engine On Even When Cold?
Both my radiator fans run all the time, even if the engine is cold. Soon as I fire it up, even if it's 0 degrees, they are running. To be clear, as expected, the fans do not run if the car is off.
Based on these symptoms, what components could be the culprit?
Camry :: 2000 Vehicle Overheating - Radiator Fans Kick In And Then Temperature Goes Down
My Camry seems to be overheating. When I'm driving the gauge maintains and reads 6/10, when the engine is idling, it goes upto 8/10, radiator fans kick in and then temperature goes down to 6/10 and keeps cycling over a period of 5 mins.
It's got 100K miles, water pump has not been replaced yet.
I checked the hose temperature; top hose 210 F, bottom hose 192, fans kick in when top hose is around 215 F.
I checked the engine temperature where the sender is installed and it was reading 205 F. Coolant level is OK. I burped the system. Previous owner told me, he had thermostat replaced by dealer.
Caravan/Voyager :: 2000 - Battery Died As Radiator Fans Staying On
So my radiator fans were staying on until my battery died and my car was completely cooled down and off. I was told it was a sticking relay so I replaced it and the fans still won't come on. I unplugged the coolant temp sensor and the fans came on so I know its not the motors or anything.
View 5 RepliesPhaeton :: Radiator Fans Coming On At Full Blast On Cold Morning
Lately, I've noticed that when I start the car in the morning, the radiator fans come on at full blast, even though it's around 20 degrees F (not all the time, but most days). My temperature gauges all show (what I assume are) correct temps as it starts out cold, water first goes to 200 and stops, then oil slowly climbs and stops at 200 I believe.
They don't climb any faster or slower that I've seen, and usually by the time I get to work (around 20 minutes), the oil temp has probably climbed about 3/4 of the way to normal while the water is steady at 200.
Is this normal? I don't recall this happening, as I would've noticed as the fans are quite loud at full blast. I haven't had a chance to run a diagnostic scan yet, but the car hasn't warned me of anything either.
Touareg :: Radiator Fans Stays On After Ignition Shut Off - Kills Battery
Believe an engine temperature sensor is bad. I took it in to get a code read, and they said it could be either temp sensor or fan switch, but didn't know which one without newer software.
Codes are
19537 - Engine Temperate too Low
P3081 - 008 - Implausible Signal
I've checked the fuse legend to see if there is a fuse I can pull, but none of them marked fan seem to kill it after the car is off, so that I can save some battery power.
I believe that I have narrowed it down to the engine coolant temperature sensor. What is the level of job this is to replace? From a parts location manual, it looks like it is in the Thermostat housing, but I'm not sure where that is.
Dodge - Intrepid :: 1996 - Radiator Fans Always Running Even At Start Up On A Cold Day
The two Radiator fans are always running even at start up on a cold day. I have not had time to investigate as yet but I am assuming it is the temperature sensor located near the thermostat or a relay. No CEL on. What it likely is and how to approach the trouble shooting?
