2008 Chevrolet Silverado 1500 2WD - Page 9 - Answered Questions & Fixed issues

Certain vehicles require exact fuel pressure try checking fuel pressure,or checking relay fuel filter for restraints on fuel,fuel pressure regulator,my sister had a issue mechanic did everything and said that there was a short until she came to me and had me fix it instead of the pros lol just bought a delphi fuel pump sometimes paying about a hundred dollars more works 97 suburban is what she drove

Brake light switch under the dash on brake pedal arm

Don't worry I'm sure you will get the solution of your problem, just check the link I attached Chevy Silverado Sierra 1998 2006 Workshop Service repair manual

I cant picture your setup from memory. Does your truck have a horizontal shock potentially infront of the front axle? It would be there to give you that "road feel/resistance" and if worn out wont do anything.

If one side is flashing too fast, that is usually caused by a burnt out bulb on the fast side. Turn on the 4 way flashers and walk around the vehicle to confirm/ locate the bad one.

P0452 OBD II Trouble Code Evaporative Emission Control System Pressure...

i may talk out of order but check the crank sensor i had one that acted that way.

run the fault codes indicates either a VSS , TR or TCM problem

How to diagnose this problem ? Viewing wiring diagrams to see what all is invovled in these electrical circuit's , check power supply's an ground connection's using a DMM - digital multimeter ! What type power seat's ? does it have memory ,heated an cooled etc ? Power Seats System Description and Operation There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function. While the passenger has 8-way power seats with heat and optional cool function. For the driver memory seat operation, refer to Memory Seats Description and Operation. Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded. If it has memory seat's there is a control module ! Battery voltage is supplied to the driver seat module through a 25 A circuit breaker. The driver seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit. Both right side windows have a seperate power supply from the left side window's ,has RT DOORS circuit breaker CB1 - 25amp. location left instrument panel fuse block . Circuit breaker's very rarely fail .Do the door lock's work on that side of the vehicle ? The windows won't work with their own switche's ? The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system) Check PDM fuse 4 15 amp ,this supply's B+ voltage to the DOORLOCK/WINDOW switch passenger side . Check for broken wires inside the flex boot from the body to the passenger door .

Sorry ,but your best bet would be to take your vehicle to a qualified repair shop that has the diagnostic tool that check's for DTC'S - diagnostic trouble code's in the 4X4 control module . Light blinking is suppose tell you that you need to take it in for sevice ,not for you to play with something you have no idea how it work's . You probably couldn't even tell me which 4X4 system your vehicle has . Transfer Case - BW 4482-NR4 Transfer Case - NVG 246-NP8 The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel. When the vehicle has the ignition key in the RUN position, the transfer case shift control module starts monitoring the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria have been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly. In addition, the switch includes a VSES request button which sends a voltage signal to the transfer case shift control module. The transfer case shift control module in turn sends a request via the class 2 data bus to the ABS control module which controls the VSES system. The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel. When the ignition key is in the RUN position, the transfer case shift control module monitors the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria has been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly. Looking at DTC'S is a far better place to start then crawling around on the ground looking at thing's you have no idea how there work. DTC B0790 DTC B2725 DTC C0300 DTC C0305 DTC C0306 DTC C0321 DTC C0327 DTC C0359 DTC C0374 DTC C0379 DTC C0550 DTC B2725 ATC Mode Switch Circuit Malfunction The range/mode switch circuit consists of 5 modes. The transfer case shift control module supplies 5 volts to the switch through the 5-volt reference circuit. The current travel through the resistor of the currently active mode. The current is then returned to the transfer case shift control module through the switch signal circuit. The transfer case shift control module constantly monitors this signal voltage to determine the condition of the mode switch circuit. When each of the modes are selected they complete a circuit through their own specific resistor. The transfer case shift control module continuously monitors the switch input to determine whether the Neutral, AWD, 2HI, 4HI, or 4LO mode was selected by the driver. Transfer Case Shift Control Switch Indicator Flashes, then Returns to Previous Mode The transfer case shift control module controls the transfer case lock solenoid. The transfer case lock solenoid is released by being energized. This is accomplished by grounding the lock solenoid control circuit during gear shifts, and in the AUTO 4WD mode. Locking action is applied when power or ground are taken away from the lock solenoid, the transfer case motor is prevented from moving. The system is capable of providing a 2HI, 4HI and 4LO lock-up without the need of additional vehicle power to hold the transfer case in these positions. The transfer case motor is a bi-directional, permanent magnet, DC motor. When energized, through motor control A or motor control B, the ground is provided by the opposing motor control circuit and then grounded through the transfer case shift control module ground circuit, the motor, through a series of gears, rotates a shaft which moves the mode and range forks to shift the transfer case between the following ranges: 4HI, AUTO 4WD, 2HI, Neutral, and 4LO. If there is a fault in the brake control circuit, motor control A and B circuits are shorted together, or a motor control driver is damaged in the transfer case shift control module, the transfer case shift control module goes into a shift block mode. The transfer case module will also go into shift block mode if there is a mechanical concern causing the shift lever detent shaft to bind, or the transfer case shift control module is not seeing a signal from the Park/Neutral position (PNP) switch. The shift block mode causes the mode indicator to flash for a period of time when another mode is selected. After that period of time has ended, the indicator reverts back to the previous mode selection. Without factory service info. to guide you through a set diagnostic procedure you probably don't have a chance of fixing this yourself .

Do yourself a favor an take it to a qualified repair shop .

check the 4WD shift motor on the transfer case If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541

Change battery in the remote

Check the fuse box under the hood. Typically on driver side behind battery. Top lifts off to expose relays and fuses.

no it indicates that the problem noise is coming from a failing suspension mount and rubber or failing wheel bearings Take it to an accredited suspension shop that can check/replace the bearings and any failed suspension parts then do the wheel alignment on the rear end first then the front end

That is code 18. Means either crank sensor or camshaft sensor error....

Could also be fuel filter or coil pack.

There should be a plastic box next to the battery that contains the ECM.

it is not a new tranny until you know exactly what the problem is run the fault codes to see if there are servo/ solenoid problems first or take it to an accredited auto professional shop for a proper diagnosis and quote

Best guess would be the electric fuel pump inside the gas tank. Common problem.
