Question about 1996 Saab 900

Running noise in the dash, runs down a new battery

I just bought this 1996 900 SE convertible. It has a new battery. Worked fine for a couple of weeks but I noticed everytime I turn the car off I still hear something 'running' (a hummmmm) from the dash. At first I just thought it was the turbo fan, but even after the fan goes off you can still sometimes her this hummm. It has drained the battery. I have jump started it a couple of times alternator appears to work, just some little wuirk in the dash. ??? any suggestions?

Ah ha! The intake valve for the interior temp. control was continuing to run after the engine was off. It was making noise (like a running fan). I removed it. So what the auto temp does not work. It is an old car... if you get hot turn down the air, if you get cold, turn up the heater. Removing this did not affect the effectiveness of the heat or air.

Replace starter. Car has been running fine for last 2 weeks, however today car won't start. Battery ok. What's the likely problem?

When you replaced the starter, I assume you did disconnect the battery. Did you clean the posts before putting your battery cable back on? I replaced my battery a couple of months ago and did not clean them and my van ran fine for several days and then one day would not start. Cleaned the posts and cable ends and everything worked fine. Just a thought. Hope this helps!

I have a mercury sable 2004 LS DOHC 3.0. The problem is when I was driving the car just suddenly stop accelerating like as if it was stuck in neutral. Every gear seems to act like neutral. I check the...

Sounds like the valve body and/or transmission pump have some problems. I would replace the complete valve body on this car. I just did one and it cleared up ALL of the problems I was having with shifting, pump noise, and torque converter lock-up. They are available on eBay for around $200 for your car. They are also fully rebuilt and updated from the manufacturer.
Good Luck!

71 c10 not staying charged... new battery alternator fuses good and new voltage regulator

Maybe it wasn't running long enough to charge up the battery?
Stop trying to jump it, when you are having problems with it dying, take the battery off and have it charged. And/or buy a $20 voltmeter to see what the battery shows. If it says less than 12 volts, it is discharged, and needs charging. A good battery that is not run down should have at least 12.5 volts. A new battery that is charged should have very close to 13 volts, maybe 12.8 volts.
When you have the truck running, check the alternator for charging. You put the voltmeter right on the battery and check it again. This time, with truck running, battery should show at least 13.5 volts. That shows the alternator is working. A good alternator will put out about 13 or 14 volts-the regulator will keep it from going any higher to prevent problems, like a melting battery or electrical parts burning out.
I would say get the charging system working right, then address the problem of dying at stop lights. That could be a carburetor problem, if the alternator is working.

2001 new beetle battery drain wont start

Alternator!!! Boost the car, if starts let it run for a few min. Once the car has stayed running for a couple of min, unhook the negative terminal on the battery, if it stays running, the battery is junk. If it dies, the alternator is junk. But this is just my past experience, and it worked.

Never know.

Car running hot, clicking noise in dash when turn the heater on

Thermostate goes bad (it might be placed it reverse way) or gatting stuck not opening. Engine might die it you wont have it checked ASAP. Also if you bought an aftermarket cap (not for GM) it might cause the ptoblem with coolant pressure. Check that it says for how much psi.
Hope that helps
Good Luck

Truck wont start .

Check the positive battery wire going down to the starter I ran into problems with them having corrosion on it. I would replace it. Cost about $50 or you could make one yourself for $12.
