List Mates, I have a 2002 996 c4. When my Air conditioner compressor is activated the volume of air coming out of the vents is decreased dramatically. It still blows cold but just very very low volume or amount. I have had it recharged , checked leaks , replaced condensors etc but nothing changes. As soon as you switch the ac off ( snowflake button) the volume of air through the vents goes right back up. Volume of air is fine on heat , defrost etc. I have never had this issue with any other vehicle. Any ideas as to what the problem may be?
I have a 2004 C2 CAB with 120K miles. I am getting bits of black foam material coming from the air vents and from under the dash. Where is this coming from? and how can I fix it? I was told there is a foam "pad" on the air flow box under located under front hood near battery.
I'd like to turn on the radiator fans at about a temperature that's 10 degrees cooler than what they currently turn on at. Is there a way to do that? Different temp switch? Reprogramming one of the computers? If reprogramming, can the Durametric Enthusiast do the job or is the Pro needed? Or some other available tool?
Durametric says I have a problem with the passenger side radiator fan. Using the Actions controls to turn on the radiator fans, the passenger side fan does not turn on in either low or high setting. Previously while replacing brake pads I removed the wheel well liner and inspected the radiator unit. The fan turns freely when manually pushed but does not turn under computer control. So the fan motor appears to have failed. Driver's side fan works fine. The fan is mounted to the radiator as a unit and it appears impossible to remove just the fan without removing the whole unit, and given the tight space it appears necessary to disconnect the unit from the cooling hoses to do so. I was hoping to avoid this and replace just the fan. I have searched and there are numerous sources for replacing the whole unit but none (that I've found) that discuss whether the fan can somehow be removed and replaced by itself. Does anybody know if this can be done? 2005 Boxster, manual, no mods.
So recently i got the P480 code. Fan was running non stop on high. When i turned the car off it kept running on high so i pulled the fuse and went to bed. In the morning i threw in the fuse and the fan didn't run.....turned the car on (Cold) and after a few seconds went to high again. Turned off the car and it ran on high for a while then shut off. So i had to do a bunch of work anyways so i pulled the fan assembly, here are the steps i've done so far: AC fan works fine, this is only the main fan. If i power the fan without connecting to the car (the small wires arent receiving signal) the fan stays off (which i think is good). If i measure the car harness side, it shows the standard 12v and 0v on the plug. The signal wires show ~.3V and 12V My guess was the 12v was the cause of the fan running. To rule out the temp sensor i unplugged it, but the 12v signal was still there. plugged the fan in anyways and it was still running. I did notice when it was unplugged the car only shows as "normal" temp, it didn't peg to the top like i'd think it would. Finally i found that F10 is the signal (Fan Final Stage) Anyone have the wiring diagram or know where this 12v is coming from? I'm 99% positive it does NOT come from the main coolant sensor. And i'm also 99% my fan is working correctly, but i don't have the "before" voltage check to know for sure. Any help would be appreciated. THanks
Yesterday I had my coolant expansion tank replace, after driving it away from the shop the temp light began blinking slowly (which usually indicates low coolant or engine compartment fan faulty) I checked the coolant level and it was fine, today I ran the car and let it sit running for a while and never heard the familiar noise of the engine fan coming on, what could have happend to the car during the installation to have this problem? I would like to have something to say to the mechanic when I bring the car back. Thank you for any insight on this problem. 2002 Boxster S Manual Tranny
So my A/C fan is only working intermittently. I search the forums and noticed a correlation between the ignition switch and the A/C fan. Coincidentally, my fan started having this problem "after" I replaced a faulty ignition switch. The symptons are that when I start the car, the lights come on the A/C unit, but will fluctuate between dim and bright. Also, the little snowflake icon does not appear. After driving for a while, the snow flake will appear and the fan will start working. It will keep working until I stop the car. My durametric will throw the "31 Fresh air blower fault", but it doesn't seem like the actual fan is the problem. Has anybody had a similar problem? I would hate to replace the entire A/C unit, if that isn't the problem. Ross
Hi, I hope you can help. I have a 2004 (986) standard 2.7L Boxster. The last couple of days There is a loud noise when the air conditioning is running. Seems way more loud than usual - especially at idle (probably because of less engine/road noise). I think the issue is that the fan behind the front bumber is coming on when I turn the air con on. The fan seems to be on anytime the a/c is on. Is this normal. It just seems very loud and I dont think it was there a few days ago. I looked at the radiator through the vents in the bumper and there seems to be a slight layer of dust on the radiator - though not too much. Could this be the issue? The problem can be heard even when I strat the car from cold. I have read that there are two fan speeds. When the A/C is turned on - what speed should they run at - how can I tell? How do I clean the dust from the radiator (preferably without having to remove the bumper)? Thanks TS
