Happened to me again. Come out to go to work to find the battery is dead because the blower fan has been running all night.

Happened to me this summer, and I was doubtful because I know it was damn hot out, but last night it was 40 degrees out.

Took it in last time and a Honda dealer couldn't find anything wrong with it.

Any ideas here?

 

I think you mean the radiator fan. Change your fan switch and see if that works.

 

Yeah, it's the fan in the front.

 

Yes it's your radiator fan switch getting jam 'cause of the moisture .

Or it's could be your motor oil temp sensor , it use to detect the temp
of the oil after shut off and will make the fan run for a while and stop
even your ignition 's key is out.
I would check the radiator fan switch first then the motor oil temp sensor.
Good luck

 

It's the radiator fan switch. I replaced mine at 50K.

Search for a picture of where it's located. It's on the right side of the block near the radiator hose where is goes into the block. It's got a plug plug on it. You just unscrew it from the block and screw the new one on.

 

this happens usually on my 01 altima, especially after some rough sriving
i just start the car again and turn it off to stop the fan
is this a bad thing to do?

 

When the fan and switch is working properly, it will run for a few minutes after you shut down the car (if it's hot enough). I would let it run it's course. Leave the Altima alone, unless it's acting like his TL in this situation.
Starting the car and then shutting it down is just more wear and tear.

 

^ thanks man, i really appreciate it

Yes yes yes ...

 

Thank you so much for the replies. This switch idea sounds right, esp. if the dealership can't figure it out.

Get this though - I get a jump this morning and take it down to the dealer, and when the tech is diagnosing he noticed my tranny is about to go to shit (dunno how he can tell, didn't ask, knew he was probably right) - so they're gonna call Acura to see if the problems grant me a free transmission under the recall. On top of that, my service writer said there might be a chance the transmission and fan problem could be related, in which case it'll all be under warranty. (I highly doubt there is a relation, but I guess the service writer can try to spin it that way.)

Anyway, got a nice 2006 TSX loaner with XM, so I'm happy as a clam right now.

Guess this Friday the 13th wasn't so bad anyway.

 

Sounds like the service dude is puffin'...but not passin'. How is the tranny related to the fan switch ? Your tranny should be covered under warranty.

 

Yeah I don't know what he's smoking either. I'm just happy they caught my tranny going bad before it took a dump on the freeway.

 

When the fan stays on, are both fans supposed to stay on or just one? I noticed my fan staying on, but its only on one side - I think it's the passenger side one.

 

dude, i would not care if they were related
as long as its all replaces for free

 

Yeah it was the passenger side fan that was on.

I dunno if I'll be all that excited to get my TL back, I'm in love with the '06 TSX loaner car they gave me.

 

which dealership in houston did u go dood?

 

John Eagle Acura. I bought the car at Sterling McCall, but John Eagle is closer to where I live/work.

When I bought the car two years ago, John Eagle was kind of on the shitty side of service, but the past two or three times I've been there, they've really stepped up. Nice guys.

They said they're moving to a new dealership in March/April, between Barker Cypress/Hwy 6. I wonder if it will be anything like the enormous "Mecca of Honda" that the John Eagle Honda dealership is.

 

Only the radiator fan will stay on (passenger) not the condensator fan ( for A/C).

 

Yes only 1 fian is for the radiator, the onther one is for the AC.

 

Damnit. Fricken' dealership gets their heads under my hood and they find all sorts of things wrong.

Guy calls me up to say my engine mounts are breaking, my rotors are warped, and I need an alignment. (But nothing about my radiator fan! Said the code was thrown by the transmission.)

Gah. Since they have it in pieces now I told them to replace the mounts, that seems like serious business, but I'll be damned if I couldn't get out of the dealership without paying for something, and they haven't even taken a look at what I brought the damn thing in for in the first place!

 

I have a 02 tls which I recently purchased with 70K miles. I noticed the electric cooling fan seems to be on all the time. I assume that this should only be on when it is needed - some temperature control. Is this correct? Does anyone have a pictur ewhere the control switch is located?

THANKS!

 

do I feel another TLer switching over to the TSX?
you wont be disappointed

 

Yes. I'm actually upset that they called me just now to tell me my car is ready. I've been enjoying the TSX so much.

I really miss the TL's V6 power on the freeway, but for the mostly city street driving I do, the TSX's I4 is surprisingly powerful, and the handling is phenominal. Incredibly stiff. The fit and finish of the thing is great as well. It's ultra tight, like prom night. Love the styling.

I plan on keeping the TL forever, but when my car loan is up in two years I'm probably most certainly going to buy a TSX (provided the new model doesn't look atrocious) to keep the TL company.

I would like this information as well. Pics and/or a DIY would be great. After replacing the transmission and the engine mounts, they still did not find anything wrong with the radiator fan/battery, which is what I actually brought it in for.

Is it as simple as popping the hood, unplugging the old switch and plugging the new one in? I'm just going to admit I'm a noob at this stuff.

Also, where is a good place to buy the part?

Thanks again for all the wonderful advice in this thread, and thanks in advance for the fan switch info.

 

I see parts online, one is a radiator fan switch, but I'm also seeing a radiator fan tempature switch. Which one is the right part to switch out? And where are they?

 

It's the radiator fan switch .
Yes it's as simple as popping the hood, unplugging the old switch and plugging the new one in . But I do not know where it locate , anyone has the pict from
Acura service manual to show !!!

 

I wouldnt. I got one as a loaner and got as far as the end of the parking lot before i turned around and asked for something different. Too small(didnt fit) and under powered.
