Do you have the performance shift on? Its the button on the side of the shifter. Pushed in is "Perf Mode" released out is normal mode. at night you will see it in green on the left, top side of the gauge cluster. If that's not it check the tranny fluid level.
It is located to the rear of the fuel tank and behind the rear differential up high.
There is a resistor pack operated by the fan switch. It has failed. You need to replace it.
the low and high beam are in one bulb. remove the battery and air filter and you will have access to them
Its causes gear shifts at high throttle at 5800 rpms instead of at 3800 - 4400 as stock computer will do in GTP

buy the book on your car car.
It will depend on year of Pontiac Grand Am and whether you are looking for high-beam or low beam. See sources and related links below to lookup by make, model and year.

Sounds like an electrical problem. Only way to determine is to take it to a reputable shop and have them dignosis the problem.
Check for a bad blower resistor at blower motor
If the transmission on a 1999 Chevy 4x4 will not shift into high gear, there could be a problem with the shift solenoid. There could also be a problem with a broken belt inside the transmission.
