Hi, this is indicating a low tire pressure issue. The first thing to do, is check all of the pressures, according to the list on the label of the driver door. I say check all, because, if you have had the wheels off, new tires, brakes, or rotations, the relearn may not have been done, and the tire positions, may not be as described. So check all pressures, and if 1 is low, this is the issue. If they are all good, and the light persists, you need to visit the dealer, as you may have a problem with a sensor. Good luck...Coop

Hi, the door panels need to be removed,there are 3 mounting nuts, and a wiring harness,(if mirrors are power).unhook the wire, take the 3 nuts off, and remove the old mirror.Repeat for the other side,and the mirrors should be functional.Good luck...

Your instrument cluster needs to be rebuilt, your speedometer drive motor is wearing out, very common on these trucks.

I'm a specialist in silverado speedometer repair check out my site at www.DrSpeedometer.com

The idle speed is computer controlled and shouldn't have to be adjusted in any manner nor is there an external adjustment screw [like old carburetors used to have] that you can turn to change anything. Usually what I find when I encounter an engine that is running too fast or slow is that there is another problem that is causing this condition. If your "check engine" lamp is on there should be a service code indicating a problem somewhere.

Six qts, with a new oil filter.

does your radio works? this dtc sets when the left channel of audio system failed, remove radio and check speaker wires for short or oen, if good change the amplifier or need for repair

it is in the center of the back of the oil pan...might have to take the skip plate off to get to it.

idle screw on throttle where the cable meets the linkage

WEll, you drop the pan. Be certain to change the FILTER.

Alternatively, consider a lube shop to do this. There is TONS of fluid in cooling lines, cooler, and converter that you cannot change at home... At the shop, they open the lines and flush new fluid in until clean fluid comes out. This is the best method, but STILL change the filter.

Your leaking gas fumes into the atmosphere. Its a health risk. All cars leak a little. Even new ones. Your leak is larger than your computer will allow. If the mechanic did not recommend a new fuel cap that would be my first choice since you can do that yourself for about 10 bucks.

Your best bet, hit a junk yard and check around for a replacement. you'd have to have special tools (in most cases) to even get into the radio to replace backlights. Either that or upgrade to an aftermarket stereo.

Your engine check light has come on. It is indicating a problem somewhere in the vehicle. This can be anything from a loose gas cap to a problem with emissions etc...

Start easy. Remove the gas cap and replace it, drive as normal. When pressure builds back in the tank it may go off.

If not and it stays on you can try removing the negative terminal from the battery for 15 minutes or so. Then reconnect. This too will sometimes clear the code.

The code did not come on for no reason. Something triggered it. It may have been a one time fault but it if comes back you should take it to a dealer and have then run the error code for you. It will tell you exactly what the issue is.


Hope this helped you. Please rate the answer if it does.

blown fuse for sure if it happened suddenly without any warning signs

hello. This is not a big problem but it should not be happening with that low level of mileage. Call the dealer you bought it from and let them know you want it fixed and that it should be under warranty. If it is not a warranty repair, drive to the nearest AAMCO or other transmission shop and have them put it up in a rack to take a look see. It may just need snugging down.

check the fuses the chime comes from the radio and through the speaker, sometimes they have an electrical seizures when the batt goes low and you try to start

In a vehicle this new, there should be a label on the fan shroud/radiator cowl which plainly says "Accessory Belt Routing" and has a pictogram to guide you. Failing that, go to a GMC dealer, find a used 07, open the hood on one, and copy it. They'll laugh at you, but you won't care. The label can be had from their parts department for about 8 bucks.

dont take off head lamp assy just check back side of lights you can replce bulbes from there.thanks

it possibly would be easier to remove the airbox out the way if you remove the headlight it may possibly put it all out of allignment and then you would have to get it re aligned by the garage, so its proberbly better to remove the airbox, it normally is quite easy to replace bulbs but can be awkward hope this helps
