Question about 2003 Chevrolet TrailBlazer

1 Answer

When I attempted to start my 2003 Trailblazer, it lost all electrical power. After a few minutes, the vehicle regained power until I attempted to start it. Checking with a voltmeter, the voltage showed normal voltage. What might be the problem?

How do i reset the alarm on my 2003 Chevy Trailblazer...I can't stay my truck.


Hello Narisol,


Excerpt from the 2003 Owners Manual.


Passlock

Your vehicle is equipped with the Passlock theft-deterrent
system. Passlock is a passive theft-deterrent system.
Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder
is tampered with, the fuel system is disabled and the vehicle
will not start. During normal operation, he SECURITY light
will turn off approximately five seconds after the key is turned to
RUN. If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before trying
to restart the engine. Remember to release the key from START as
soon as the engine starts. If the engine does not start after
three tries, the vehicle needs service. If the engine is running and the
SECURITY light comes on, you will be able to restart the engine
if you turn the engine off. However, your Passlock system is not
working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to
check the fuse. See Fuses and Circuit Breakers on page 5-85.
See your dealer for service. In an emergency, call the M
Roadside Assistance Center. See Roadside Assistance Program on
page 7-5.


Excerpt from the 2003 Owners Manual.

Testing the Alarm The alarm can be tested by following these steps:
1.
From inside the vehicle, Iower the driver's window and open
the driver's door.
2.
Activate the system by locking the doors with the power door
lock switch while the door is open, or with the remote keyless entry transmitter.
3.
Get out of the vehicle, close the door and wait for the SECURITY light to go out.
4.
Then reach in through the window, unlock the door with the manual
door lock and open the door. This should set off the alarm. When
the alarm is set the power door unlock switch is not operational.
If the alarm does not sound when it should but the headlamps flash, check to see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers on page 5-85.
If the alarm does not sound or the headlamps do not flash, the
vehicle should be serviced by your dealer.

I lost all power in a 2005 Trailblazer. Called GM and they said to kick the key forward and wait 10 min, and this would reset it. It did but now the radio A/C door locks and windows don't work. What...


Do it three times in a row.

1. Perform a security system relearn.
2. Let the vehicle sit for more than 10 minutes with the key off.
3. Attempt to start the engine, leave the key in the run position monitoring the security system indicator.
4. After 10 minutes, the security indicator will change state.
5. Turn the key off and wait 10 seconds.
6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
7. After the second 10 minute timer has expired, turn the key off for 10 seconds.
8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
9. After the 3rd 10 minute timer has expired, shut the key off for 10 seconds.
10. The security system will relearn on the 4th starting attempt and the engine should start and run.

Soon after starting and driving for about 1 minute my car putters and losses power for about 10 seconds then regains power. (2003 Hyundai)


Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

Reduce engine light comes on with a/c use.


Most likely it is the fan clutch as it is computer controlled. I have had 2 in the shop this year with the same problem. To be sure, have someone check the codes before you start spending your hard earned dollars.

the first place to start is the flashing engine lite. that means cylinders are not firing at all or improperly and driving it like that for even short period could cause heavier damage. particularly valves and cat converter(s) the computer really needs to be scanned for codes in order to proceed. did the oil lite come on before or after engine quit. after engine quit would be normal cause it stalled. its possible that it needs spark plugs and/or coils. or more
