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.

Engine Size : 5.3 l
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.


Chevy Silverado Trailer Button

Question: trailering button dosent work on end of sifter----Chevy Silverado 1500 4wd HD

Answer: First check all the fuses. If they are good, you will need to Check the switch itself. Find the 2 small wires as they go from shifter into the steering column, put an ohm meter on them, press the button. The meter should sjow open when not pressed, and good continuity when pressed.

    How Things Work

    Exhaust Recirculation System - Known As EGR Valve

    The Exhaust Gas Recirculation (EGR) system is used to lower Oxides of Nitrogen (NOx) emission levels caused by high combustion temperature. It does this by decreasing combustion temperature.

    The main element of the system is the linear EGR valve. The EGR valve feeds small amounts of exhaust gas back into the combustion chamber. With the fuel / air mixture diluted by the exhaust gases, combustion temperatures are reduced.

    Code P0420 Catalytic Converter Failure

    To control emissions of hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx), a three-way catalytic converter is used. The catalyst within the converter promotes a chemical reaction which oxidizes the HC and CO present in the exhaust gas, converting them into harmless water vapor and carbon dioxide. The catalyst also reduces NOx, converting the NOx to nitrogen.
