  1. AC temp gauge and fuel gauge issue

    9000 Workshop
    See this thread, which is still on the front page: https://www.saabcentral.com/threads/9k-cluster-fuel-and-temp-drop-intermittent.720854/ The culprit is a bad connection between the EDU connector and its PCB. The fix is disassembling the EDU and reflowing the connector.
  2. Noise and vibration after lowering the car

    9000 Workshop
    There's no real standard for tripod bearing size. Any time you mix cups and shafts you run the risk of a mismatch and the slightest bit of play can result in what you describe. Use the axles whole if you can. Also, the stock struts were designed for the stock ride height. Rule of thumb is...
  3. 3D Printed a Dash Fascia?

    9000 Workshop
    Why print the entire fascia? You can buy or print an adapter that will mount three gauges nicely in a DIN bay. thingiverse.com is probably the single largest repository for free models. Most of the files there are STLs. I don't know if Fusion 360 can work with them, but Blender can.
  4. 9K Cluster fuel and temp drop intermittent

    9000 Workshop
    I reflowed the through-hole connector on the EDU which connects it to the vehicle. I wicked away the existing solder with a braid and flux and replaced with 60/40.
  5. 9K Cluster fuel and temp drop intermittent

    9000 Workshop
    Reflowing the EDU connector with 60/40 and plenty of flux seems to have done the trick. I can no longer reproduce the problem. I'm going to call it fixed and button it back up.
  6. 9K Cluster fuel and temp drop intermittent

    9000 Workshop
    It doesn't appear to be any cable or interconnect. I've separated the EDU from the rest of the cluster to isolate them mechanically. I can readily reproduce the problem by giving the EDU a good rap with a screwdriver. The fuel gauge flinches then goes to zero along with the coolant gauge...
  7. 9K Cluster fuel and temp drop intermittent

    9000 Workshop
    I pulled out my cluster today. I see the same issue where temp and fuel gauges go to zero and the A/C stops. I tinned the mating surfaces on the two flex circuits and coated them in dielectric grease. Time will tell if it works.
  8. Hissing sound when accelerating

    9000 Workshop
    Check the IAC plumbing underneath the throttle body. It's a press-fit connection that often pops off. If it truly is coming from the back of the car, the fiberglass packing in the mufflers can unravel and clog the exhaust.
  9. 1997 CS noise increase

    9000 Workshop
    There are no backpressure / O2 sensor issues with swapping out mufflers. Have an exhaust shop delete your intermediate muffler, then decide if that's enough sound before spending any more money. I'm running an intermediate aftermarket glasspack leading into the largest 2.75" Magnaflow...
  10. Pain in the **** rear bulb sockets

    9000 Workshop
    Except for gasketed sockets used on virtually every other car.
  11. Pain in the **** rear bulb sockets

    9000 Workshop
    Corrosion was an issue on my car, and no water had even gotten in. The contact to wire junctions had gone flaky over time. The entire setup is weak and wired up like a kid's 100 in 1 electronics kit. The socket retention is also trash and not set up to withstand the forces inherent in...
  12. Pain in the **** rear bulb sockets

    9000 Workshop
    Taillight assemblies are trash. Drown everything in dielectric grease and you might stand a chance.
  13. 9000 wont start

    9000 Workshop
    Is there any tach activity during cranking? Is the main injection system relay working?
  14. Intermittent power locks

    9000 Workshop
    You'll need an iron designed for fine work. If it has a trigger, forget it. Hot air rework is less risky. Sub $100 stations are available on Amazon.
  15. Intermittent power locks

    9000 Workshop
    Unclip the box from underneath the steering column and remove the wiring harness. Then slide open the box by prying some tabs. How good are you with soldering?
  16. Intermittent power locks

    9000 Workshop
    Black box located under the steering column.
  17. Intermittent power locks

    9000 Workshop
    Usually bad solder joints on the module. It can be reflowed with hot air or and iron and plenty of flux. With hot air, be careful because the PCB doesn't tolerate high temperatures well.
  18. Telltale signs of a dodgy stock BOV

    9000 Workshop
    Yes. If we're going to bring price into the discussion, cheap Chinese wheel hubs could be considered "better" than OEM. I don't feel strongly either way about the Bosch valve. It's the disposable razor of BOVs. I just prefer the serviceability and adjustability of aftermarket units. It's...
  19. Telltale signs of a dodgy stock BOV

    9000 Workshop
    Therein lies the value of an adjustable aftermarket unit. A few turns of the screw (or a cheap spring replacement) and you're back in business rather than trashing the whole part. A part that is equal in performance and superior in longevity, is superior on the whole.
  20. Telltale signs of a dodgy stock BOV

    9000 Workshop
    Who said anything about the appearance? If something as stupidly simple as this device (with one moving part) fails, I'm not replacing it with the same part. I'm choosing something that can't or won't fail the same way. The same reason I chose an all aluminum radiator; I'm tired of dealing...
