1999 Blazer gear selector

The standard instrument cluster contains a microprocessor. The instrument panel cluster (IPC) microprocessor communicates with other controllers in the vehicle over the Class 2 serial data bus. The information passed over the Class 2 bus, along with direct external connections to other controllers and devices provides the inputs that are used to operate all of the gauges and the illuminated displays in the cluster. Some displays and gauges are operated directly by external sources (devices or controllers) and others are under software control of the IPC. As the IPC microprocessor runs the operating software, the microprocessor continuously processes Class 2 data in order to determine the correct values and states to display. PRNDL Indicator (Park Reverse Neutral Drive Low) The PRNDL display is a variable function electronic display located in the IPC. The PRNDL display is capable of displaying PRND321. The display electronically illuminates, or lights the back of the desired character in order to indicate the gear selection in the transmission. The IPC controls the PRNDL by use of the Class 2 messages that are received from the PCM/VCM. The vehicles with automatic transmissions have an electronic park reverse neutral drive low (PRNDL) range indicator. The system uses the signals from the neutral safety back up (NSBU) switch on the side of the transmission. Signals from this switch determine which LED is in the electronic PRNDL will light. The system is electronic. No internal adjustment is needed. Refer to Transmission/Transaxle for diagnostic information.

1999 Chevy Blazer backfires inside the engine and

in order for the engine to pop back in the intake it has to be firing when an intake valve is open.The best place to start would probably be the distributor cap replacement.the toughest part of this job is the smal torx bit screws on the cap and not breaking the distributor. the screws were threadlocked ,and the distributor is made of plastic.be careful not to over tighten.

How do I siphon gas from my 4 door chevy blazer

the best way to do this is to disconnect the fuel line from the top of the manifold, run a hose from the line to a gas canister, and turn on the key-the tank's fuel pump will empty the tank. best to have an assistant to operate the key while you monitor the filling procedure.

My 1999 chevy blazer runs fine when cold but 20 miles or so the rpm gauge starts turning off and on... i can feel power lessening when its turning off after a while it turns off compleetly but car still runs just not as well

Hook up a fuel pressure gauge an see if you are not loosing fuel pressure causing this running problem. Hook it up to the fuel rail with a long enough hose to locate the gauge where you can watch it while you are driving. If you are loosing pressure then check for fuel resistance in the line, fuel pressure regulator or fuel pump going bad.

When it Rains, My 1999

it could be the distributor cap is not sitting correctly, lay a piece of sandpaper down on a flat surface and place the cap on top and rub it round a few times, this should help it seat better, only other thing i can think is the icm might have a crack in it and damp is getting in this will stop a spark being made. if it is you can clean the crack and fill with liquid bonding glue, dont matter what type just leave it to dry for 12 hours and keep filling with the glue till its spelled the crack, when dry it should work fine in all weather.

Why my 1999 Chevy Blazer 4.3, engine starts, runs about 5 second, dies and then won't start, if you wait 10 minutes it starts and runs fine, this happens once every few weeks/months or twice in one da

You may be having an intermittent failure with the fuel pressure regulator - checking the fuel pressure when the truck won't start may pinpoint this problem. If the pressure looks OK, this same problem can be caused by the ignition system as well (ignition coil or control module).

I saw what you replaced, didn't see any testing? What testing have you done? Make sure battery has a full charge? When the problem is ongoing, have a helper crank it, while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Any applicable trouble codes? If you have the spider fuel system, that system is noted for problems.

I have a 99 blazer

A great place to start would be a tuneup. Plugs and wires, cap and rotor. If the check engine light is on, have the codes read. Places like Autozone and Advance auto parts will do this for you for free. Their hope is that you will buy parts from them.
