Question about 1999 Pontiac Grand Am GT
When it is running with jumper cables on it it makes a loud noise
Don't always think about the more complex probs, as most are simple and can be done by any decent backyard mechanic..I don't know about the rest of you folks, but I inquire on this website for I DON'T have to take it to a mechanic...you have to have more confidence in your own abilities...I try to answer questions for that particular person does't end up taking it to a mechanic...I feel thats why they inquire on this website in the first place...garages are SO high in their prices its getting kind of ridiculous...don't ever leave a car running with jumper cables for more then a few minutes as it can shorten or burn up your electrical componets that some require less than one volt to operate...unlike the carburated of cars years past today's cars are more sensitive to the voltage changes it receives...see if battery charges up OK with a battery charger...it should be fully charged...the noise you hear if its a high-pitched whine could be a burned out diode in the alternater...if your battery is more than 3-4 yrs old its probably needs replacing...I'm constantly surprised at the number of people who always suggest you take it to a garage as most automotive chains (particulary Auto Zone will chek your charging system for nothing...obviously if they detect a problem they expect you to purchase the part from them...make friends with some of your neighborhood back yard mechanics...it'll save you alot of money!!...because of the fact that alot of electrical componets require less than a volt, its imperitive you keep the charging system up to par for its putting out between 12-12.7 volts (although I believe it can drop to a minimum of 11 volts).a simple electrical tester is a must have as your first tool ($10-$20) ...goog luck!!

I think its you alternator, the battery and alternator kind of work back to back with each other. I will take the car to shop that you know and can trust and have them diagnose the car all together. Good Luck.

Sounds like a bad starter solenoid, usually cheapest and easiest to replace the starter and solenoid as a unit. It is always best to check for power between the solenoid and the starter with a test light, if the solenoid clicks but the test light doesn't light up you have found the problem in the solenoid.

You need to replace your crankshaft position sensor located by the harmonic balacer. These sensors heat up and cut off the engine until the sensor cools down. This happens with age and it is not specific to GM.

Bad front wheel bearing on the drivers side. When you turn left it shifts more of the vehicles weight to the passenger side and takes the pressure off of the drivers side. Not uncommon but will need attention soon. Hope this helps
