I had several expensive bits fail on the climate control on my ‘93. They’re old cars, so it’s hard to complain about a blower motor failing after 30 years. Overall I still love the 964, and haven’t found any other classic weekend car I would enjoy or trust more. You can’t really replace it. I will add that Porsche Classic actually still offers spares for these older 911s, so I’ve not encountered any issues that couldn’t be resolved.
Hi Jon, You are absolutely right, but regarding the blower motor, I'm on my third set in 2 years which were finally correctly installed, so that's why I was a bit pissed ^^ The Porsche department for replacement parts is the main argument why I absolutely enjoy and love the brand. My problem is that I have lost trust in companies for jobs I had to do by a third party. I guess my problem is that I am very picky and emotional about my cars, I've always been, and considering how much money I've already spent over the last 2 years (>30.000€) , I get upset very easily when people don't respect your property. For them it might just be any other car, but for you it's your one and only. I only had one issue that couldn't be solved right away, and that was regarding the ABS high pressure pump which was not available at Porsche. Thank you for your comment ^^
@@lxapproduction I understand the emotional component -- my wife likes getting new cars often, but I'm quite attached to my 964 and plan to have it as long as I can drive. I'm fortunate to have found a terrific Porsche Classic tech who has owned 964s and rebuilt his own gearbox over the weekend. He knows these cars down to the last bolt, and is very detail-oriented. Granted most techs aren't at that level...
I understand the frustration. It’s hard to trust anyone especially when the knowledge on these cars is fading from the world. Regarding the car dying clutch in, could be the vacuum lines like you said, could be the ICV like you said you bought a new one. But also like you said the lightweight flywheel. Make sure your ecu chip is tuned specifically for a light flywheel. Regarding the gas nozzle stopping prematurely during fill up. All 964’s owners go through this. Some pump design work better than others. But the trick is to turn the nozzle a full 180 degrees. So the hose going into the nozzle is vertical and sticking straight in the air. The issue is the tight bend in the fuel hose feeding into the tank. The effect of pressure change which normally cancels the full up is amplified by the design of the 964 hose/tank. This is somewhat defeated when the nozzle is straight up in the air.
Fading knowledge, that's what's so sad about classic cars. I think the vacuum lines are now fixed, and I've replaced the ICV in the meantime. Because I'm working on replacing the starter motor too, I didn't get to test whether the problem is now solved or not, but it can't possible be worse than before. I know about a performance upgrade that goes together with the installation of a light flywheel, but that comes at a cost of 2500€, and that's not something I was planning on doing just yet. I've tried the 180°, but then it spits out even more fuel. I'm currently "happy" with a 90" twist HAHA Funny how so many 964 owners have the same issues. At least its reassuring that I'm not the only one :)
So sorry to hear about your frustrations. Please do persevere, you are really getting through this well. Once the car is sorted it will stay sorted. Mine is now over 215k km and it is giving me no problems at all.
Thanks for posting these honest thoughts of your car ownership. Too many times, we get a romanticized view of ownership while the headaches go undiscussed. To solve your fueling issue, you have to rotate the nozzle 180 degrees and then insert into the filling nozzle.
That's exactly it! I've tried to be as transparent as I can throughout my journey and even though it has been very frustrating at times, I still think it helped me think more positively about what I had to go through. About the nozzle, it works indeed, but I still have splatters of fuel on my fender even with the leather protection. I can live with that though 😊
You need to only hold the fuel pump lever halfway. It needs to fill slower. The speed of the newer fuel pumps causes splash-back which triggers the pump to shut off. I’ve had 3 classic cars that require this.
I’ll give it a try next time. I have the feeling that some pumps only allow the nozzle to be either on or off, but I’ll check it next time ✌️ the rotated nozzle gave me the best result so far, and the small splash protection is doing its job of keep the dribbles off the fender.
I have the same phone mount as you, also attached to the time-of-day clock, but because mine is RHD, it's by the driver's door, leaving the CCU free. Why don't you mount yours on your fuel/oil level gauge so it's by your door? Mine is also in the workshop, having broken down last Wednesday after an annual/12,000-mile service. Coincidence? I'm looking at new HT leads and either the hall sensor in the dizzy (the actual fault code) or the crank sensor (which was replaced in 2014). There's always a job to do, but they're great fun!
I’m used to having my infotainment and phone mount on tge right, I guess I didn’t even consider mointing it elsewhere simply out of my habbits? Will it not be in the was of the keyhole or the vent? My center vent is blocked off because of a faulty servo for now, so if it were to block off the left vent, that would not be an option for me
@@lxapproduction My car is at the garage because I have an ignition issue! When it's fixed and back, I'll take a photo. From memory, it obscures the headlights switch, not the vent.
Going through exactly the same issues as you. Both my rear heater boxes were stuck. Managed to take them apart, sort out the flappers and refit them….but broke one of the holding studs on each side and found a solution to that. The rhs blower fan on my 89 car fell out after I had changed it. I think because it doesn’t have the retaining screws of the later models and the plastic clips were worn. Fitted self tappers and fingers crossed.
A retsining screw would be really really helpfull 😬 I have a broken clip on the heater box, so it really is a question of time until it will fall out again
I bought a new one, will fix it this weekend! I also got the single mass flywheel, maybe that’s the main cause, but I’ll still replace it in order to exclude every other probable errors in the system
@@lxapproductionhave you also checked the mass air flow meter? I still think the key culprits are being identified by you from isv to vacuum leak to light weight fly wheel. Swap back to the stock dual mass.
Hi I would go for the ISV, (Idle stabilizer valve) for your engine trouble. I saw that another guy adviced also the same. Unfortunately this expensive part do not specifically need to be replaced but simply cleaned with ultra sonic device. A pity that you bought a new one... Concerning the tank refill it is very known that you have to twist upside down the gas hose... No other way to avoid that... If you plan to repaint your front bumper don't miss to put back in shape the lower grid of the bumper which in your case, "doesnt smile" the right way :). Finally for the cruise controle knob as far as I remember, If you remove your steering wheel and the cover of the full mechanism of lights and blinkers, you can tight a little screw that holds your cruise control knob. Agree with you that no professional is trustable... and it's a real issue... This is why as far as I can do, I do it myself... and if I can't, I learn how to do... Best for the rest...
Hey. I've already replaced the idle motor but since I'm working on replacing the starter motor right now, I didn't get the chance to check whether it made any changes or not. A friend of mine from Australia said it would be best to replace them, since they are not that expensive. I will not throw the old one away, but I also don't want to have any sort of selfmade problems in the near futur, or having to clean it every other month or so. Yeah the refilling is bad, but at least knowing that I'm not the only one is reassuring :) Thanks. About the front bumper, I know, my cars "grun" in bad, but my lower grill is also broken. I've put it on the list of things to be done ^^ For now, I focus on the technical bits on the car and maybe tackle the esthetics during the winter months. Thanks for your comment.
@@lxapproduction Thanks. As of now an ISV costs about 640€ + postage... Everything is about to know what you consider expensive or not, but I do consider it is... :) Specially if you can avoid to spend such money by cleaning it... lesson to learn. It's really easier to change for new when possible but often it's not the only cause or the real cause of the troubleshootings...
Trust me, I would consider 640€ plus shipping extremely expensive, I'm nowhere near as wealthy as to say that amount would be cheap. I got an aftermarket one for 153€ at FVD.net www.fvd.net/de-de/96460616000EQ/96460616000-leerlaufsteller-964-89-94-944-85-91.html I haven't read about it being possible to clean it, because then I would have started with that. I always try to refurbish first, and if it doesn't work out, replacing it with the best value for the price. Regarding the troubleshooting, I've checked the vacuum lines first, then a possible air leak on the intake, and the next "cheapest" solution would be the ISV. Some comments also say that with the light flywheel, even a new ISV wouldn't change anything, and I would need to change the chip in the ECU to make it understand what's going on with the flywheel. That would be the next step then, but THAT's very expensive and comes at a cost of 2500€! And that's absolutely out of my budget for now.

So true. I always wonder how people without any mechanical knowledge can afford to own this type of car.

I had a similar issue with the engine cutting out on my 964. After I cleaned the idle control valve (very easy to do yourself) the problem went away.
I bought a new one, will fix it this weekend! I also got the single mass flywheel, maybe that’s the main cause, but I’ll still replace it in order to exclude every other probable errors in the system
