Top 10 2005 Chevrolet Silverado 1500 2WD Questions & Answers

i work at a chevy dealership,just had the same problem my fix was to replace the power door lock relay located on drivers side interior fuse block

I have a 2007 chevrolet silverado and my service airbag light came on. I was out camping with the sterio going and ran the batt low but their was enough juice to restart after about 10 min. On the way home the service light stayed on and i just fixed the problem which was a fuse under the hood in the main fuse pannel. It is very common due to low voltage on start up to blow a 15 amp fuse.

I had this problem myself and come to find out it was a blown fuse which also controls the outside temp display and compass built into the rear view mirror. Check in your fuse box located under the hood on the driver side, open the big black box cover and locate the airbag fuse. Pull it out and check to see if it is burnt. Replace it if necessary.
Hope this helps you

My airbag light will not cut off and my temp and compass on my rearview mirror cut off the same time it went out too... I changed the fuse because it was blown... it works for a couple of days and then cuts back off... I took it to the dealership and they did a dianogstic check and can't find the problem

Here is an exploded view

Check the wire harness to your alternator and get a proper voltage reading at the battery with a volt meter when the engine is running. With the engine not running you should have a reading of 12.0 to 12.5 Volts and with the engine running the voltage at the battery terminal should be at 13.5 to 14.5 volts. Do this reading with out anything on, and then turn everything on like your head lights and blower fan on high. The voltage should not drop under 13.5 volts. If your having low or high voltage reading, the voltage regulator has gone bad. With a high reading, there is a short in the system somewhere causing the alternator to put out extra voltage which is bad for the whole electrical system like the ECM and fuel pump causing them to fail also due to the high voltage. A bad battery with a short in the cells it self can also create this problem, you may need to just replace the battery to fix the problem, most parts store can test the alternator and battery for you free of charge like Auto Zone or Parts Source to determine if it's just the battery, but most likely your battery will also have gone bad due to the extra voltage in the system. The extra voltage will over heat the battery acid causing it to slowly dry out and the elector plates in the battery warp and short each other out causing the spike in the voltage reading and the battery drains it self in a few days or hours, depending on how bad the short is in the battery. As for the Tech reading between 4000 to 6000, is related to the extra voltage in the system and have the Parts store like Auto Zone pull any DTC codes that can check to see if it's a bad crank or cam shaft sensor that is causing the bad reading. Start with the simple and work in the battery and alternator.

The voltage regulator controls or regulates the alternator's output. Think of it as the brains of the charging system. It senses how much voltage is needed by your vehicle, then modifies the field current within the alternator so it puts out just the right amount of current. Too little current can allow the battery to run down while too much can damage it and other electrical and electronic components. When the regulator fails, the charging system usually ceases to function -- except in cases where the nature of the failure causes the alternator to run wild and overcharge the battery. In any event, the only cure for a dead or defective regulator is replacement.

Most regulators have been mounted in or on the alternator itself. This was done by the vehicle manufacturers to simplify wiring and assembly. It was also made possible by advances in electronics that allowed the regulator to be reduced in size to a small chip.

Unfortunately, internally regulated alternators are packaged as a unit -- which means that if either component fails (alternator or regulator) both must be replaced. This is because internal regulators are not available separately (at least not to the general public or the typical service facility). Electrical shops and remanufacturers who rebuild alternators can get them and can replace the regulator separately if that's all that's wrong with the unit -- but they'll usually charge you the same as if you bought a rebuilt alternator.

The truth is, the high cost of labor today has made it impractical for most service facilities to fool around trying to rebuild or repair components like alternators, starter, fuel injectors front-wheel CV joints, transmissions and even engines. It's faster, easier and usually cheaper to simply replace the old unit with a new or remanufactured one than to try to overhaul or fix it. Besides, most new and remanufactured parts come with a guarantee. Good luck and hope this helps you determine what's causing the over chairing, keep me posted.

Hi Jim, The Exhaust Gas Recycle valve is usually mounted on a tappet cover and is connected to the the intake manifold. It has the function of recycling the fumes from the sump and burning them in the combustion chamber. Regards John
