Default Flashing Air Recirculation ?

Hey guys, I have noticed for the 2nd time my Air Recirculation light flashing. It does it for about 5 seconds sometimes. Does anyone know what this means? I was running the heater earlier and wasn't trying to recirculate the hot air.

I've seen that a few times. Couldn't find any documentation on it though. The outdoor temperature flashes at 37 degF as a warning and the OM outlines that, but nothing for the recirc light blinking.

The only thing I can think of is that it's warning you that the air is hot? I will bring it up when I get my oil changed next time. Yeah I've seen the flashing 37 degrees but no documentation on the flashing light on the air recirc. Thanks for the response.

This happened to me today in my 2011. First there was a short squeal sound from the engine. Then the recirculate light flashed about 3 or 4 times. This was on the first start and it is extremely cold today.

My 2011 just did it this afternoon. I drove for about 30mins...parked for about 5 mins...started car with all electronics off and in neutral.....recirculation light flashed about 5 times and than stopped. Car started up and drove fine....does anyone know what this means? It was 55 degrees outside and mostly Sunday. Can't think of any reason this would happen on my 2011 wrx with 7200 miles on it.

Happened again today. About 80 degrees, drove the car for about an hour, stopped and turned of car/all electronic components. 15 mins later, started car and the recirculation light flashed about 4 times. Anyone know why it did this?

Nope. The only 'flashing' reference in the OM/FSM is to the temperature gauge which flashes when it hits 37 degF to warn of potentially slippery bridges.

I don't know if this would apply to the WRX but I found this on a Forester forum:

Hey everyone, I had an issue last week where when starting my '09 Subaru Forester the recirculation light blinked several times after starting up the vehicle. I did a web search but couldn't find any explanation for it so I emailed Subaru and got a reply from them a day or two later. I figured since I didn't find an answer when searching for it, I'd share the info here so if someone else does a search for the info they'll hopefully find it.

In their reply, Subaru explained that the recirculate light blinks if it detected a problem during the system self check. They went on to say that since it only occurred the one time that it's not an ongoing issue and that nothing needs to be done at this time. However, if it occurs again in the future (even just momentarily), then I would need to bring the car in.

Anyways, if anyone needs this info I hope they find it.

Thanks for the good info! Crazy that this is not stated in the manual. It's happened maybe 3 or 4 times in the past 6 months. I wonder if it's worth the trip to the dealer. I thought that was the purpose of the CEL.

You sir are a better searcher of the FSM than me . I searched for 'flash' and 'flahing' but not 'blinks' .

It happened to my 09 once in the 15k I owned it.

The diagnostics section is a tough one, but the new manual is actually easy to dive through.

It's the error code that it's throwing. So if the blink is faster, it's the one, and so on. You may want to bug your friendly dealership to have them check it out with their diagnostics software.

just installed 4 sets of lights on my 2008 STi last night(previously had 3 installed with no issues). Lights are all PIAA(2 sets of 510s, 1 set of 520s and 1 set of CC HIDs). Instructions say to wire them into a 15A light source, so I spliced from 4 fuse wires into 2 and plugged them in with my 15A lighting fuse in the fusebox.

Didn't start the car last night because all 4 switches lit up green ready to go.

Went to start the car this AM and at first try it hesitated to start. After 5 seconds of cranking I stopped. Went to go start it again and it fired right up, but the Air Recirc light flashed. It flashed about 5-10 times. I didn't count how long it was illuminated each time, but it was likely .2s signalling a short.


figured this might be useful for someone searching the future. yay, time to troubleshoot!

I feel that when this happens, the car is not starting right up for whatever reason. It has happened in hot and cold weather which is odd.

Did you guys that had this problem happen to have the recirc button enabled, along with having where the air comes out from (head, head/feet, feet etc etc) set to auto?

Or possibly even the fan set to auto with the recirc button enabled? <--- I don't think that's the cause.

This happened to me once the other day. I noticed that the dial that controls where the air is distributed was set to auto.
Before I shut the car down, I set all the dials to "off" with recirc still enabled, started the car and I have not seen this happen since then.

Thread necro. Had the flashing Ricirc button a few days ago and have been researching the issue. To expand on jonklein611 post...a bit more detail of what the flashes mean, only problem is you need to be plugged into the Subaru Select monitor to enter the diagnostics mode on the HVAC system. They can narrow down which sensor is acting up.
