Thanks for the reply,,BUT...the battery is discharging due to a closed contact,leaving the battery to died after a week or so. There is NO key or start here. the car is stored
in my garage & not a daily driver,so after a week or two the battery is dead or at least needs a jump. the faint noise is from the the engine's bay, cowl near the firewall/windshield location. I believe the faint noise is the blower unit not turning off. If I disconnect the battery ,it goes off. place the cable back on the noise is there once again. No startup or ign. is needed to cause this problem. So I have to believe it's a relay or switch causing this "closed" circuit ? Where do I start ,the relay ; fresh air blower relay G1 sells for about 10 dollars. Is this it ? & where is it located on the dash? If it's not the relay ,can it be the switch on the DASH as you mentioned?
I can get both parts but would like to eliminate the battery discharge now. Perhaps its the Ign switch ,some one said,but with the key out can there be this problem?

Hi IronHorse, ok, that noise you hear is definitely the vent fan. I DO believe there is a relay that controls this. However, since you have a 1985, I'm not totally sure. In 85, they changed the model half way through the year, and the two are completely different electrically, and somewhat mechanically as well (as well as a completely new interior). The easiest way to tell is... if you have the interior of a 924, then you have an early 85, if you have the same interior that the late 80s 944s have, then you have the 85.5. I don't know if you already know this, but for the sake of explanation, I figured I'd throw that in. On the old models, the fan relay I BELIEVE is located on the second row (further back). You'll want to check that. On the newer ones, I have no clue, but I am pretty sure there should still be a relay for it.
 
Also... I don't think this is it... but I would check. There is a motor (believe it or not) for the cruis control. In the older 944s (83-85), this motor is located on the rivers side, near the cowl, right inside the engine bay in front of the engine. When these go bad... they just run forever. A quick fix is to simply disconnect it's wiring harness. Not sure if this could be your problem, but I would just check it out to be sure. My 84 944 had a battery discharge problem, and that ended up being the culprit.
 
Hope that helps.
 
I would also suggest you check out www.RennList.com it's a really great web site and there are like several thousand people on that list with 944s.

Thanks for the suggestions,
The blower FAN ,sounds to be the problem,since I removed the battery cable the fan turns off,attach the batter leads and on it goes. there is NO key or IGN on .
So is it a RELAY? if so where is it located ? or the next step.....

To lady in Milwaukee. If I had to do it again, I would spend more for a cleaner car, the devil is in the details. I have an early 83, I think, under the hood it says March 1982. I have a booklet, the types dimensions and tolerances put out for Porsche on 944's. It says for Model 82,83 . What is the difference and is my March 1982 referred to as an early 83? Jon

Yeah, I completely agree. I just sold my 1984 Porsche 944, and took a huge loss. I had 8 cars, and my wife is pregnant so I thought I'd downsize to 6. Porsche had to go. I spent $1,200 buying the car, put about $4,000 into the car, and sold it for $2,000. It's just one of those things...
 
I kept some of the really rare pieces (like the Euro front bumper, etc). I do plan to get another one, but when I do I'll probably spend an extra 2 grand up front to save me from having to dump twice that into t later.
 
I've learned that, at least on a 944... for every $1,000 you save, you end up spending $2,000 to bring it to the condition you would otherwise have if you spent the $1000 in the beginning.

What is the difference between the 82 and 83. What do I call my March 82 944, is that an early 83 or something else? I have the 3 blade fans. My vin is WPOAAO949DN450293 my original registration shows YR. Model 82. My 944 is slow off the line, kind of feels fuel starved, it bucks a bit. I have new fuel injectors. After that first 3 seconds or so it performs flawlessly. The car came in around Port Hueneme California. What site can I go to, to see the paint choices in 1982? They are slightly different from 83 I believe. I can see the names but not the paint chips.

Skidder, I assume you're in the United States, right? If yours is indeed a 1982 model, then it's pretty rare. VERY few of the 1982 models actually made it to the United States (something to the tune of about 100 or so). It doesn't particularly make it any more valuable... but it does make it significantly more rare since the model wasn't introduced in the United States until 1983. It was introduced in Europe in 1982.
 
The problem you're having is without a doubt, a problem with your AFM (Air Fuel Meter). That is that grey looking thing with the grey flap in it. It's inline of your intake and it bolts onto the back of your air box. Those get old, and the gradiated sensor on the door gets worn out. I was able to buy a rebuilt one by Python on eBay for $75 bucks. They are pretty expensive. A new one is about $250 bucks. But I guarantee to you that your car will run like brand new.
 
Another thing to take a look at would be your "reference" sensors. They are located on top of the transmission bell-housing. They normally sell for something like $200 each, BUT... BMW used these same sensors in the 7 series model back in the early 80s. You can buy these for $75, and they are identical in every way... the only difference is that the length of the wires are a little bit longer, but that's not a problem.
 
I would check the AFM first though.
 
You could also need a new TPS (throttle position sensor). That's much cheaper, and easier to replace... but I still think it's your AFM.
 
I would go to RennList.com

Dear Todd82ta: Thank you so much for that information, You should know I am so appreciative of this info.. I don't know how to thank you, unless on the slight chance you are a hunter, I have a large tract of land in Southern New Hampshire you could hunt on. I am Skidder440 with a 1982 model 944. Celebrating my 10th anniversary with my first and only, thanks for helping me to make it even better, it could use all the help. Jon

Hey man, no problem, I'm really glad I could help. NH is an awesome state. I've never hunted anything, but my grandfather owns land in the mountains and a cabin in West Virginia. I proposed to my wife up there. I live in Fort Lauderdale though.
 
If you get bored, check out my site... lots of pictures of my 944 if you're curious about some of the work I've gone through fixing it up.

unfortunately, I don't have my 944 anymore, but you can see it if you click on "Past Cars" and scroll down to the bottom.

I live in galveston behind seawall and never had water this high since 1900 storm. in fact, never had water in garage since house built in 1901 whcih it has seen at least 7 large storms.
 
i left the porsche in garage and the water got about 15" high, several inches under the fuses & relays-which they do not appear to be blown except 1 fuse which was replaced. the interior dried out nicely. The oil & filetr was changed. The battery was drained and it recharged fine. I have lights. The engine will not turn over and the only sound is the vent fan and what may be the gasoline pump. I do not see relay for starter listed in owner's manual? since the battery was drained, could the water over the starter fried the starter? or any other possibilities. Please Help! I have restored most of this car at cost of about 18k over last 15 years and really feel bad that we did not have the one more driver to get it to Houston before storm.
 
Thanks
Ted Labuzan
