Top 20 2005 GMC Sierra Questions & Answers

There are some videos that may help, but the easiest thing is to get the vehicle to an auto electrician. His pro grade scan tool computer will show what the fault is.

Could be something as simple as the connection came unplugged. If not, disconnect it at the lug and check it with a test probe to see is there power from the harness to the motor. If no power, check fuses and connection at the sending unit.

change both of them

Is the parking brake engaged?

Change both axel bearings at the same time. The pinion bearing can be tested by slowly turning the drive shaft by hand and listening for any rough spots. It could be a carrier bearing or a bad U joint too. Isolate it by dropping the drive shaft and turning the pinion yoke by hand. If there is a problem, you'll be able it feel it. Then look at the drive shaft for worn carrier bearing and U joints.

You might want to check the ball joint. None of them have grease zerks and can dry out. They will cause a noise when turning or hitting a bump, if really bad. Hope this helps.

Hi Anita: If it had been running fine up until the maintenance that you describe, I would be checking what had been done. -The first concern would be the oil used, and the amount. Is it possible that it was overfilled or that the wrong kind of oil was used? Please reply as a comment to this post and I'll try to assist you.

I have always looked things like that on YouTube.

Yes....Try this.....With the wipers OFF,grab & move said wiper arm in the same direction as if you have switched the wipers on.........If said arm moves,in most cases,there is a nut holding said arm to the 'splined' pivot.Tighten said nut & re-check wiper arms for proper 'park position'......Additional adjustment may be needed.....Hope this helps :-) If you need further help, reach me via phone at https://www.6ya.com/expert/ralph_2f0886b7d6af32ce

It is more than likely an alternator problem. Charge the battery and drive to an auto parts store, and they can check the alternator on the vehicle for free.

Check ur trans fluid level. Warmed up in park on level ground

I have a 2003 GMC it has two buttons to use 4 wheel drive as most all do with push button controls...One is for standard highway driving with 4 wheel drive the other is for 4 wheel drive a low speeds for off road driving and conditions that need low speed less spin driving..not designed for highway use..and must be stopped to engage where 4 speed highway can be shifted on the go..hope this answers your question..good luck..

I know you said the security light isn't on but it sounds like an anti theft issue. Read this over I think its what your looking for Do It Yourself GM Security bypass

I presume this is an automatic transmission. If so it is likely your transmission fluid is low. There may be other problems, so I recommend you take to a professional transmission shop. It may be a minor problem and a little preventive attention may save your transmission.

You can replace the thermostat...it is relativity inexpensive to do..you will lose some of the antifreeze from tne top of your engine due the thermostat being a little lower then the top of the radiator..HOWEVER....Having a GM truck I believe that you have two separate problems...one the heat not coming on properly..your inside the car heat system works by sensors and activation mechanisms that work/move the doors within the heat/cooling housing..The common problem is the activater that moves from heat to cool visa/versa is defective or tne inside door is not operating properly...the activater is not to much of a job just above the gas pedal on the end of the heat/cooling housing..the other..door is on tne inside and quite a job to get at...The other gauge problem,if more the one of the gauges are fluctuating it is your computer board electrical system powering the gauge cluster..A COMMON PROBLEM ON GM AND CHEVY TRUCKS AND VANS..they can be re-calibrated but must be removed...if only the heat gauge...it may be your heat sensor on the engine block..again not a hard or expensive job..but is an important sensor..it controls the the fans that cool the engine and senses the temp of the water going to your heater core...A defective one could be sending false readings to your inside heat sensors in the cab..I.E heat not coming on right..my first bet would be CHANGE THE HEAT SENSOR.. Then go from there.Hope this helps..good luck
