20 Most Recent 2001 Chevrolet Blazer Questions & Answers


The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

The check engine light is an early warning system to protect your engine from malfunction. There are several sensors within your engine that trigger this light. If you have your owners manual there will be a section in it that tell you what to check. The basics are ;
engine oil level
coolant level
blocked air filter
but the list can go on so look at the manual.

Which of these does your vehicle have ?
The NVG 233 transfer case features a 3 button shift control switch, located on the instrument panel.
The NVG 236 transfer case features a 4 button shift control switch located on the instrument panel.
Do you know what DTC'S - diagnostic trouble codes are ? Both of these 4X4 systems can set DTC'S , Having a professional or factory scanner is what is needed to check for these codes . Not a OBD 2 code reader or autozone , advance etc... The four button system can set a bunch of them .
DTC B2725
DTC C0300
DTC C0305
DTC C0308
DTC C0309
DTC C0310
DTC C0315
DTC C0323
DTC C0324
DTC C0327
DTC C0362
DTC C0367
DTC C0374

DTC C0611

The NVG 233 transfer case features a 3 button shift control switch, located on the instrument panel. When the ignition is in the RUN position, the transfer case shift control module starts monitoring the transfer case shift control switch, to determine if a new mode/gear position has been selected. At a single press of the transfer case shift control switch, the lamp of the new position begins flashing to inform the driver that the transfer case shift control module has received the request for a new mode/gear position. The lamp continues to flash until all shifting criteria has been met and the new mode/gear position has been reached, or has engaged. Once the new mode/gear position is fully active, the switch indicator lamp for the new position remains ON constantly.
The NVG 233 transfer case provides the driver with 3 manual mode/gear positions:
• 2HI - 2 Wheel Drive high range
• 4HI - 4 Wheel Drive high range
• 4LO - 4 Wheel Drive low range
Any of these mode/gear positions may be selected while driving the vehicle. However, the transfer case will not allow a shift into, or out of, 4LO unless the following criteria has been met:
• The engine is running.
• The automatic transmission is in Neutral, or the clutch pedal is applied on manual transmissions.
• The vehicle speed is below 5 km/h (3 mph).


Finding out what if any codes are stored should be your first step .

You may need someone to help with this, or not.Turn off the radio and any accessory that will interfere with hearing the fuel pump. Turn the key to the on position,the fuel pump should turn on for a couple of seconds to build fuel pressure, and then the pump will shut off. Turn key off. Turn the key on, the pump will do the turn on and off again. Do this about 5 times. Do not turn to the start position until after the 5 times of building the fuel pressure up in the lines. After the 5th time, turn the key to start the vehicle. If the vehicle starts, then you're loosing fuel pressure when it's not running. Most cars have about 60 psi of fuel pressure. You'll need a fuel pressure meter to check it.

I had the same thing happen when my battery terminal was loose; it killed the alternator, so the battery doesn't get charged. There are cheapo battery/charging system testers that plug into the socket, or your local auto parts store often offer free testing of the alternator and battery.
