I'm having a few problems with my 85 900S turbo and am looking for some advice. First off, the temperature control has gotten extremely hard to turn and last week the plastic knob broke. In taking it apart I found that it is mechanically connected to something which looks like a valve deep behind the dash. Does this need replacing, how do I go about it if it does, and what's the level of difficulty here. Second, when I have the car on and idling, there is a scratchy wining noise comming from behing the glove box on the passenger side. If I turn the fan on then it goes away, but if the ventilation system is turned off it starts up again. It will breifly stop if I step on the gas, but at a constant speed the noise comes back. Does anyone have ideas about what this might be and ways to fix it? Third, I had noted that I was having a 5mi/gal drop in gas mileage lately and the most prevalent fix (or at least the easiest) suggested by others in this group was change the gas filter. I did and haven't noticed an increase in the gas mileage over the last two tanks of gas. Could this problem and the noise under the dash be related. Any other suggestions for improving gas mileage, the plugs have been recently changed as well as the air filter. What about the distributor cap or the APC solenoid (it makes clicking sounds at idle when the car is hot and has just been driven for a ways). Thanks again for all the great suggestions. This newsgroup is a terrific resource. Also, if somebody could repost some of the best places to get saab parts online I'd appreciate it. I need to get ahold of a new lock solenoid for the driver's side door cause mine doesn't work anymore. Cheers, Jeremy
