2005 Chev pickup Silverado 4x4. 5.3L. Question Here: push the button to engage four wheel drive and it don't work. Light don't even blink. Is this a common problem and what do i check for?

Answer: The problem with your Silverado could be several things. First, check all the fuses. Especially the one labeled "4WD" in the dash fuse block, but best to check all in there and under hood block. If there are no lights at all on the switch, it could be a bad switch. If there are lights put they don't switch, it could still be the switch, the transfercase control module, or the encoder motor on the transfer case or front actuator- depending on the type you have. Need to have that module scanned for codes. Using a scanner with live data to see if the switch is working, voltage to the encode motor etc. is needed to diagnose this system properly. Have had all these things fail, the encoder motor is a little more common, but an expensive guess.

Question: 1- when turning left and only left sounds like something is rubbing . you know? 2- feels like play in driveshaft checked u-joints by trying to move drive shaft up- down and left and right didn't move held yoke on rear end turned driveshaft has play truck has 1570000 miles what should i look for ?

Answer: The noise may very well be the u-joint. While holding the yoke and turning the joint, if there is any play, then it is bad and needs to be replaced. Depending on the torque of the shaft and how the u-joint is worn, it may only do it when turning one direction. There may also be a worn engine or transmission mount that is causing the noise. It would hard to say without hearing it myself. A lot of different things happen when turning the steering wheel. Things flex, bend, etc. If the noise is worse when accelerating and turning, then I would say it may be more than just that u-joint, but get that replaced first, then re-evaluate.

    Power Steering- Electric- How Does It Work

    The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions.

    Oxygen Sensor Code P0036 and P0056

    P0036 - P0056
    Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. A heating element inside the HO2S minimizes the time required for the sensor to reach operating temperature.
