20 Most Recent 2014 GMC Sierra 1500 Questions & Answers

Look in your manual the ports will be connected to another fuse.

If you put in LED bulbs, they don't draw enough current for the computer to see them.

Do you have the book that came with your vehicle? that should tell you. My car one did.

Use scan tool to clear/erase codes.

This will be listed on the sticker inside your drivers door and also in the manual.

Fuel injected gasoline engines have fuel pump in gas tank. Pump is supposed to "emulsify" (fancy word for "mix") fuel and water to help prevent a localized build up of water at bottom of tank. But ...water and gas don't mix and if you have too much water (caused from condensation ...especially in the winter ...and consistently keeping your fuel at low levels) things don't work so well. Dry Gas ...ancient stuff from carburetor days and frozen fuel lines ....get some, a couple or three bottles at least, and pour into your gas tank then fill up. Dry Gas is essentially (methyl?) alcohol that will break up the water and allow it to better mix with the gas.

the automatic module for the system needs checking or replacing

Intermittent faults rob years from our lives!!! I've rather a root canal to intermittent fault isolation!! Chapter 11 of Murphy's law reminds us simply checking various spots will cause the fault to disappear until you really need to go somewhere. Could be a loose or dirty connection so check the fuse box, even if the fuse look good remove clean it and replace. Hopefully you can easily get to the back w/o removing the entire panel. Change the bulb. Finally is it is a current year model let the dealer do it, should be covered(or not disallowed).

hope it helps

should be somewhere in intake hose

contact the opener manufactures/ distributors and get the operating frequency of the receiver unit . You may need the services of a radio technician to adjust the sender ( remote) to that frequency

2wd, or 4 wd????? use a ruler. (caliper tool?) one way to find out , no tools.? is to try to buy lugs. and it tells you. autozoned shows 1/2 in. - 20 Thread 2wd. still not metric, wow, amazing, we are. or take off one lug nut walk in to any hardware store and see if 1/2" x 20TP bolt screws in. if not try all sizes in bin. ask clerk to help, its not hard to do. if buying nuts, why not ask the sell this. they know. no job stated. so speculate that. are you buying lugs, or the wrench that fits them>???????

You actually have 4 of them, an upstream and a downstream on each bank of cylinders. You only replace the one that failed. The code will tell you, Bank 1 or Bank 2, and Sensor 1 or Sensor 2. https://www.google.com/search?q=2016+gmc+sierra+1500+replace+o2+sensor ..

I will be able to tell you. Just need to know if 2x4 or 4x4 and if it is 1500,2500, or 3500

4wd or 2? well the RPO tag tells you which tranny box is there, and matters. some cars have more than one transmission used, GM sure. 4L60E is common. 700 is useless code means tranny problems but 717 sure in turbine speed, and is on the tranny oil pump the turbin connect to the pump. 8 transmission use no counting the diesel so learn to read YOUR PRO codes. ALL GM cars /trucks all have RPO codes. (as builts) and will tell you in 1 second what M coded transmission is there Mxx but this this sensor is not easy reach. I will do just 1 the 4L60, have full manual on it. 2photos for you of ISS, (aka) Automatic Transmission - 2ML70 Automatic Transmission - 4L60-E/4L65-E/4L70-E Automatic Transmission - 6L45/6L50/6L80/6L90 Automatic Transmission - Allison id 249 IN this photo deeper, we see 250 ID.and the pump in your hands, or TC removed.TC does not fall out of cars, we yank the whole tranny back on a tranny jack tolleysorry not easy .

Rather than swapping out, why not get the one you have repaired and rebuilt? Doing swaps with other model years only works reliably a year either way because of changes in the electronics. https://www.google.com/search?q=transmission+repair+near+me ..

check and test the front sensors for damage and rust around the sensor port gm had problems with with rust getting under the sensor ring where it would bolt on to hub
