Question about GMC Yukon XL

2 Answers

2007 GMC Yukon XL When key is turned on, dash lights come on and show no problems, but vehicle will not start. Have checked all fuses and installed new battery - starter will not engage. Is there a reset switch? The vehicle was running fine a few hours ago. I was attaching a trailer to the rear electrical plug-in, and this problem happened immediately following that plug-in. Please give us your suggestions. Thanks

Check the fuses in the fuse relay box under the hood,look for a max fuse that may have blown,also,try and twist the battery cables,to make sure they are making good connection,but do not take them off unless you have before,cause the memory could be lost from the computer,now,there is a relearning process you can do,if this does not help,turn the key on,leave it on for ten minutes,then turn it off,and right back on,do this three times,a total of thirty minutes.This will relearn the key to the ignition,let me know how you come out,but check the fuses first,and twist the battery cables to make sure they are making contact good.You might try charging the battery also.

    Turn the key on,and put your foot on the brake,move the shifter to drive 1 than all the way back to park,then try and start,if this does not work,try to start the vehicle in neutral.Does the starter click?Try having someone turn the key to start and hold it there while you lightly tap on the starter.If it starts,then the starter is the problem.

There are some possibilities which you will have to check in this case:--
1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.
2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.
3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.
4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.
5) If all the above possibilities mentioned above checked out OK/perfect then it’s a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

2007 Yukon Xl Denali can the headlight switch/dimmer cause only the tail lights to not work. Dash lights, signals, brake lights when pressed work. Both sides went out. No blown fuse or broken wires.


If front park lights are working highly unlikely headlight switch is the issue. Is the vehicle equipped with a trailer towing package and wiring to the rear? I would start there. This vehicle may also have a taillight module located under the vehicle on the passenger rear attached in the wheel well area that goes bad

I disconnedted my battery and now air does not blow out of my dash vents. Worked before I did this. 2005 Yukon 5.3 liter v-8 any suggestions


In the under hood fuse block there will be a fuse labeled HVAC. Pull it out for about a minute then put it back in. Turn the key to the run psition, do not start the vehicle. You will hear the HVAC system ging through a self calibration process. After a couple minutes you will no longer hear the actuaries moving. Turn the key off and then start the vehicle. It may take a couple of tries but eventually it should recalibrate and you'll be good to go.

2002 Gmc Yukon xl. Drove it one morning and returned home than ten mins. later went to start it and nothing. Dead. Turn key to on and all dash lights go our and nothing. Doesnt crank or anything. ...


Take the battery out of it and go to a auto store to get it checked, they do that free, but you might need to get it charged or get a new battery. If it clicks then it's definitely the battery, otherwise it could be something completely different.

Things to consider
-oil change?
-last tuned up?
-battery age?
-Alternator?
-check fuses?
-are you aggressive while driving it, that can cause internal engine problems over the years.

hope it helps.
