Undo your negative cable for 30 seconds ,,it may reset itself,,,

EGR valve - exhaust gas recirculation valve .Which engine does your truck have ? 4.8L, 5.3L, 6.0L and 6.2L Not all have an EGR valve , some have Camshaft Actuator System The cams are controlled allowing exhaust valves an intakes to over lap , allow exhaust gas to be drawn back into the cylinder ! The camshaft (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by, changing the angle or timing of the camshaft, relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening, during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.

If haven't already tried this, bend a hook on the end of coat hanger, try to fish for the rod inside tailgate, maybe you can catch it?

No. The bolts are common off the shelf bolts The markings on the head of the bolt will tell you what material the bolt is made of and the torque range it will withstand.

The knock sensor adjusts the timing dependent on load conditions of the engine. It also compensates for changes in the fuel octane rating. If the engine is pinging or detonating it can damage the pistons and in the worst case under heavy load actually burn a hole in the top of the piston. This sensor also effects the milage.

take off the plastic cover above the grill and unscrew the headlight mounts disconnect it then disassemble the casing then replace the light and put it all back together

Power actuator not working

Probably not the flasher unit...when one signal blinks fast, (front or back) the opposite (front or back) bulb us usually bad...bad bulb, dirty connection, or wet...Hope this helps.

Replacing TPS will reset the light but will stay in memory until the computer is reset. For help to change throttle body sensor check out you tube :How To Install Replace Throttle Position Sensor Chevy Silverado GMC Sierra.

They haves for the turn signal

follow the vacuum line from the canister should be on or near the intake manifold

unscrew the bottom of the box see if it will flip down far enough to see inside?

THE CLUTCH ON THE A/C COMPRESSOR IS SEPARATE I DO BELIEVE. WHEN RUNNING WITH A/C ON. ON THE RIGHT SIDE OF THE ENGINE COMPARTMENT THERE IS AN EVAPORATOR CANISTER / CONDENSER IT SHOULD HAVE A PIPE ON EITHER SIDE AROUND THE HOOD HINGE. WHEN RUNNING PROPERLY ONE SIDE SHOULD BE HOT ONE SHOULD BE COLD. THE FREEZING COULD BE FROM HUMIDITY AND HIGH AMBIENT TEMP

Hi, this is a pretty common problem on these Silverado instrument clusters. We can repair it for you or provide you with the parts to do it yourself. Click here to learn more about these Silverado instrument cluster problems: Dr Speedometer Instrument Cluster Repair Speedometer Repair Guage...

I hope I don't live to regret this...When you first start your motor it is cold. It does not need a fan. When it gets hot the fan will come on bringing the temp down so the fan no longer needs to run. When you drive down the freeway the fan does not need to run because it has plenty of air flow. But when you are not moving the fan needs to cool things down so it will cycle on and off.

You have a loose connection somewhere, either on the power side, or on the ground side.

Fuse or bad horn

cruise controls have an on/off button in the hand control that enables you to disable the cruise control. ON some stalks it is a press in button on the end of the stalk
