your heater core is partially plugged causing water slush, if you have checked your drain plug on the evaporator heater case outlet and it is not restricted, then that is a major repair.

Probably bad spark plugs, wires or ignition coil. Also cylinder number one spark plug is prone to cracking. If you cant isolate a cylinder pull each plug out and inspect for carbon tracking or plugs worn. Recommend using AC Delco original equipment replacement spark plugs.

Check your 60 amp fuse in the underhood fuse box and see if it is good.

Sounds like the car is going into limp mode which does not mean there is a tranny problem. Take it and have it hooked to a code reader, you will need to find a garage or something because the cheaper ones that are sold in your local automotive supply stores dont read the trans codes. Another option is to turn head lights on with the key NOT in the ignition and take the negative cable off the battery, then remove the positive cable, wait 10 to 15 minutes then turn head lughts OFF, recinnect the positive THEN the negative battery cables. This will reset the on board ECM.

Passenger side of the fender under the hood - check the fuse relay box - about $12.00 a piece - they do go bad from time to time.
exchange the power lock relay with another one and test the locks.
then put the relay back and go to the autostore.

DTC P1631 Theft Deterrent Fuel Enable Signal Not Correct

The powertrain control module (PCM) controls the fuel injector operation and the starter operation based on a vehicle theft deterrent (VTD) password from the vehicle body control module (BCM). When the ignition is first turned ON, the BCM sends a programmed theft deterrent password to the PCM. The PCM acknowledges the password and responds to the BCM that normal fuel injector and starter operation will continue. If the PCM detects an incorrect password, a theft deterrent system failure, or an attempted vehicle theft, DTC 1631 will set. The engine will not start or crank as long as the condition is present.

Diagnostic Aids
DTC P1631 indicates that the vehicle theft deterrent password that the PCM has learned does not agree with the password received from the VTD system. This condition can occur if the BCM has been replaced and the PCM Password Learn function has not been enabled. If the BCM has been replaced, the password must be relearned.

Did you perform the Diagnostic System Check - Vehicle?
Go to Step 2
Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
Perform the Password Learn Procedure. Refer to Programming Theft Deterrent System Components .
Did you complete the procedure?
System OK

30-Minute Learn Procedure
Turn ON the ignition, with the engine OFF.
Attempt to start the engine, then release the key to ON; the vehicle will not start.
Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
Important: The vehicle learns the Passlock™ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
Start the engine. The vehicle has now learned the Passlock™ Sensor Data Code and/or password.
With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.

Could be any number of reasons why this happens . The headlamp switch , the dimmer switch the headlamp relay , the BCM - body control module , wiring , connections , ground etc..... Without testing no one on here could say for sure what's wrong . Do you know how to test electrical circuits ? Viewing wiring diagrams then using a DVOM - digital volt ohmmeter to test the headlamp electrical circuits . Possibly hooking up a scan tool an checking headlamp switch input data to the BCM an seeing if the BCM is energizing the headlamp relay .
Free wiring diagrams here http://www.bbbind.com/free-tsb/ Enter vehicle info. year , make , model an engine size. Under system click on lighting , then under subsystem click on headlamps . Click the search button then click on the blue links .



You can use the headlamps two different ways.
• Place the headlamp switch in the HEAD position for normal operations.
• Place the headlamp Switch in the OFF position for automatic lamp control (ALC) operation. During ALC the low beam headlamps are on for daytime running lamp (DRL) operation in daylight conditions or low beam headlamps and exterior park lamps on in low light conditions.
The DRL/EXT Fuse in the top underhood junction block supplies battery positive voltage at all time to the coil side of DRL relay, left low and high beam headlamps. The EXT LTS Fuse in the top underhood junction block supplies battery positive voltage at all time to the right low and high beam headlamps.
For normal manual low beam operation when the headlamp switch is placed in the HEAD position, ground is applied from G203, through the low beam contacts in the headlamp switch to the body control module (BCM).
The BCM then applies a ground to the headlamp relay control circuit. This energizes the headlamp relay in the left I/P junction block allowing ground from G201 to be applied through the switched contacts of the headlamp relay, through low beam contacts in the headlamp dimmer switch then to the left and right low beam headlamps, illuminating them.
For high beam operation the headlamp dimmer switch is placed in the HIGH position, ground is then applied from G201 through the switched contacts of the headlamp relay, through high contacts of the headlamp dimmer switch to the left and right high beam headlamps, illuminating them.
When the dimmer switch is placed in the HIGH position, the indicator lamp input to the BCM is pulled low. The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp.
If the headlamp switch is left in the HEAD position, the inadvertent power control feature will turn off the headlamps after 10 minutes after you turn the ignition switch to the OFF position. If you place the headlamp switch in the head position after the ignition switch has been turned OFF, or if the ignition switch is in ACCY position, the headlamps will remain on until you turn them off or until the battery runs dead.

I have a 2005 Impala with 16000 miles on it .Every thing works on the radio fine but I have very low volume . I cant find out what wrong

Sounds like either something is jammed in the seat track and/or the track has to be replaced and that is a complicated operation there as I have replaced a number those. everything has to go back exactly as it came out or you have to take it out again and correct it and that in itself is no fun. Like I said, it may just be something jammed in the track but also, it could be a broken seat motor drive shaft and in which, the seat track or more commonly referred to and "seat module". That should be left to someone who has ahd experience in replacing them because they can be very tricky. I hope this helps you, Jesus loves you, John 3:16-17 (KJV)

If it overheated and warped the cylinder head, that would cause a no start. Do a compression and leak down test to see if the head gasket is damaged.

I think you could use this manual method instead.. My nephew who is a full time mechanic uses it
of the times, and all mechanics look up to manuals. It's very easy he gets it from. www.reliable-store.com
