I have '04 60R with 55,000 miles and need info on the following questions -<p>1) My AC was running last night even when I turned off the fan and turned off the engine. Any explanation for this? <p>2) Could this be due to clogged air intakes next to windshild?<p>3) Battery was dead this morning - how long should it last?<p>4) Error message saying "position light malfunction" What's this?<p>Thanks for your help.<p>Still love this car.<p><br>

Re: Several questions (ZogeNY)

#1 is the afterblower function i think. its a good thing to my knowledge to prevent that musty smell from coming out of the air vents when the AC is turned on. gets all the moisture out. i think it may also turn on to help air out the cabin if it gets too hot inside.<p>#3 maybe it ran (like it usualy does and you havent noticed it yet) and the battery was already weak and ran it down. i think it usualy runs for about 5-10 mins. it did on my s80, i havent noticed it yet on my 06 R.<p>#4 maybe the battery was dead a long time and it lost the info about the headlamp position if you had it in the off position or the bulb burned out?

your a/c condensor runs in order to ensure its dry before it shuts off. this is normal.<p>position light malfunction is a burned out rear tail light. there are two 5W bulbs on each side.

Re: Several questions (ZogeNY)

Your battery probably went because it's older, the outside heat so the blower ran a bit more than it usually does.<br>Don't just charge the battery up, make sure you <B>test it</B> for full charge capacity<br>(This is normal, but possibly you may have had a time sensor go bad and it ran too long)? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <br>It's supposed to run for about 40 minutes, it starts about 1/2 hout AFTER you shut the car off

Re: Several questions (ZogeNY)

#4 pertains to any position light having burned out. This includes the two rear L/R parking/running lights, the two front L/R parking/running lights and the L/R front side turn indicator light. This message indicates that one or more need to be replaced or maybe jiggled to return to working condition.<p>Not to worry, my local Volvo dealership service dept says they replace around 100 bulbs per week for their customers. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

Re: Several questions (ZogeNY)

A dead battery throws a bunch of communication codes that need to be cleared by the dealer. I have had to do this more than once.

Easy enough to check the filter which is under the glove box. You will need a 25 Torx. Replacement filter is about $30. Get the IAQS filter regardless if your car has IAQS.<p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>ZogeNY</b> »</i></TD></TR><TR><TD CLASS="quote"><br>3) Battery was dead this morning - how long should it last?<br></TD></TR></TABLE><br>I plan on 3-5 years of life. Do not play games with a failing battery. Too much hassle if they go dead. Volvo now has a direct relationship with Intersate battery, check with an Interstate dealer. Make sure it is properly vented.<p>In regard to afterblow fan running down the battery, one of the parameters that determines afterblow run time is battery voltage. If your battery is too low, afterblow duration will be shortened or eliminated.<p>I will not pile on to what others have stated in regard to the error message.

Re: Several questions (JRL)

My 2005 owners manual says 5 minutes run duration, 50 minutes after shut down. As I recall my 2004 had the same values. The observed behavior is consistent with those values.<p>Trust me, I know far more about the "afterblow" function than any sane person would care to know.<p>It took 18 months of dealer trips, memos, phone calls to VCNA etc. to finally convince them that it did not work on my car. All that finally resulted in TNN 87-53, dated 11-21-05 where Volvo finally admitted that not only were cars not shipped with it enabled, but there is no way to enable regardless of what VIDA would have the tech believe. There still is no VIDA update to fix the cars that it is not working in. The regional rep. ran a manual script to enable mine, however it is not something that is generally available yet. It will be a VIDA update.<p>Of course it was not just my car, but many 2003 to 2006 models. The only product not impacted is the XC-90 V8, which does not have the function at all. <p>I would be a little concerned about run durations you suggest, since the evaporator fan is about a 10 AMP load, and I am not sure I would want it running for 40 minutes. <BR><BR>

It took a lot of effort from the us, the consumer, to get the ball rolling on those issues.

Questions answered

Thanks for all of the great and timely input.<p>Can I assume that due to the extremely high humidity we've had lately in NY that the blower runs longer?<p>Battery seems to have recovered. I wouldn't expect a battery to go after a little more than 2 years.<p>Thanks for position light info. The right rear taillight has a bulb out.<p>FWIT, I'm still running the same rotors after 55,000 miles and no pulsing.

The Volvo HVAC systems have no humidistats in the system. The only sensors in the cabin are cabin temperature, evaporator temperature, and an "air quality" sensor if you have IAQS. There is a sun load sensor on top of the dash. Outside air temperature sensors are in the outside rear view mirror. There is no way for the system to know relative humidity.<p>The major impacts to "afterblow" run time are battery voltage, and compressor run time. If you have been running the AC in colder weather, that means the compressor has not cycled much, heat and moisture have not been removed from the incoming air, and therefore no condensation has formed in the evaporator box. <BR><BR>

Re: Questions answered (rogersampson)

Is the "afterblow" feature found only in cars with the IAQS option? My '05 V70R doesn't have IAQS, and never has done an "afterblow"

Re: Questions answered (MAC1LSR)

Automatic, or manual with or without IAQS all current models have it, with the exception of the XC-90 V8. It appears with that vehicle they had some power management issues and opted to eliminate one "power consumer", however that is some speculation on my part.<p>Just because your vehicle has it, and just because VIDA says it is enabled does not mean it is working! That is what TNN 87-53 is all about. <p>A simple test is to run your car with AC on for a minimum of about 10 minutes, and when you park it place some little pieces of tissue, say 1 inch square, lightly in the vent outlets. Clearly these should be blown out of the vents when the blower comes on some 50 minutes later, assuming it does.<p>This is a binary feature it either works or it does not. Please make the above simple test before taking it to your dealer to confirm it is not working. I am sure they do not need Volvo hypochondriacs. <p> At the other extreme do let the dealer convince you that conditions were not right for the afterblow to come on. If you drive the car for more than 10 minutes with AC on, and you have enough battery to crank the engine, the conditions ARE met. <BR><BR>

Re: Questions answered (rogersampson)

So is there really no way to turn the afterblow on for the average Joe who wants it to work?
