Used parts such as starters and altinators don't last. It might **** but it sounds like you need to buy a new starter,altinator, and battery. Or just start with buying one at a time.
There's not much information to go by. From the sound of it you have a faulty alternator which eventually drained the battery. Have the battery checked as well. If you install a new alternator with a junk battery, you will have the same problem again.
Using the Driver Information Center (DIC)
Important: After resetting, the tire pressure monitoring (TPM) system requires up to 8 km/h (5 miles) of flat, smooth road straight line driving in each of the 4 speed ranges to complete the calibration process. For further information, refer to Tire Pressure Monitor Description and Operation . If the TPM system does not reset, refer to Driver Information Center (DIC) Switch Inoperative .
Set all tire pressures to the recommended kPa/psi. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .
Turn ON the ignition, with the engine OFF.
Press the vehicle information button until TIRE INFLATION MONITOR SYSTEM PRESS (down/left arrow) SWITCH TO RESET is displayed.
If the system is being reset due to a low tire pressure condition, press and hold the down/left arrow button until TIRE INFLATION MONITOR SYSTEM HAS BEEN RESET is displayed. If the system is being reset due to a tire rotation, press and hold the down/left arrow button for 5 seconds.
Release the down/left arrow button and TIRE PRESSURE NORMAL is displayed.
You need to understand how they work , do you know about automotive electronic controls ? Your switches are just inputs to the BCM - body control module !
Door Locks Power and Ground
For door lock operation, the IP Fuse Block supplies battery positive voltage, through the 15 amp DR LK/TRUNK fuse, to the BCM. The BCM uses this circuit exclusively to apply power to the door lock actuators. The BCM is also supplied a ground circuit, which it uses exclusively to ground the door lock actuators. When a door lock is pulsed, the BCM internally connects these two circuits to the appropriate lock and unlock control circuits to actuate the locking or unlocking functions.
When diagnosing door lock malfunctions, these circuits must not be confused with the other battery voltage and ground circuits of the BCM. The appropriate wiring schematic must be used to locate the correct circuits. Failure to identify the correct battery voltage and ground circuits of the BCM during diagnosis of door lock concerns may result in misdiagnosis and unneccessary parts replacement.
Passenger Door Unlock Operation
When the BCM detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuators transition to the Unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuators. This is done so that the driver door may be unlocked individually before unlocking the passenger doors using a keyless entry transmitter or an automatic door unlock function, if programmed. When the keyless entry transmitter is used to unlock the passenger doors, the BCM requires a repeated unlock command before it performs the unlock function. However, when the unlock input is from a door lock switch, a single unlock command is all that is required to unlock all doors.
How to test computer controlled door locks
Hi William:
Usually the seats are attached to the floor by four bolts.
Removal is a matter of opening the door,
put something soft on the ground to protect your knees
With a flashlight, look under the seat to locate the bolts.
With a socket or combination wrench, remove the bolts
unplug any electrical connections,
PRESTO!
Out comes the seat.
Have you tested the battery in the remote. Most auto parts stores have a display to check the frequency from the key fob to see if the battery is good. If the battery tests good ,go through the info button for the Driver Information Center(DIC) to see if the valet has been turned on/off.
Hi it's possibly a blocked filter. An oil and filter change might do it of if there is some where that could a complete flush would be better. Regards Jim...
The warning light means there is a trouble code which you may already know. The computer commands the relay to turn the fan on, and its not happening. So the trouble code is set.
If you are getting a ground from the computer at the relay, it could be a wiring problem. The computer grounds the relay to power the fan.
On some models one fan is for engine cooling and the other is for ac.
The service engine soon could be an indicator that you need to have minor maintenance done in the near future. I had a Grand Am that the service engine light would turn on when I was getting close to needing an oil change. You might check your owners manual for an exact reason as to why it turns on.
