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.
Can you make a 98 Chevy blazer two wheel drive
That is what the pushbutton control on the dash is for. As far as a front end conversion is concerned, really no practical way. You could swap it for one from a two wheel drive S10, but that will also involve changing the transmission to one without the PTO and modifying the control circuits..
2.2l. Do I have to lift the motor to get to the oil pump?
Hello. Raise and support the vehicle. Drain oil and remove oil pan from engine block. Remove the oil pickup tube assembly from the intake side of the oil pump cavity. Remove and replace oil pump gears. Good luck and keep me informed; if you want to.
2004 Chevy Blazer dash lights don't come on
If the rest of your lights are OK, there may be a dead spot on the dash dimmer control (near the headlight switch). Cycle the control a few times to see if that fixes it. Otherwise, check the fuses at the left end of the dash.
My 1998 blazer wont stay in 2 hi it sound like it is whining roaring really loud
this is because its not fully shifting back into 2 Hi. make sure vehicle is in neutral and idling, push the 4 Low button listen for a shifting sound or whirring noise. then push 2 Hi button. it flashes while it is attempting to shift you should hear a shifting clunk or whirring noise, then the light will stay lit. after shifting from 2 wheel drive to 4 wheel drive shift into reverse before selecting drive on the column. the rpm going so high is because your vehicle is still in 4 wheel drive. the low gearing results in high rpm. if it does not shift into 2 wheel drive : there is a shift actuator on the transfer case, check the cable connected to it. this cable is connected to the vacuum control pump deal that controls you cruise control. this pump is located directly under the battery box. the plate the battery sits on must be removed in order to see it. check any wiring there and check for vacuum leaks in the lines connected to it . this pump actually pulls on the cable going to the shift actuator. check that the cable is attached and the baffle on the pump is moving. you can manually pull the cable by hand, while having an assistant operate the buttons inside the cab. this will release the actuator in the transfer case allowing the transfer case to shift properly. basically its a locking mechanism, locking the transfer case in the selected gear range. it must actuate in order to complete the shift
