GMC - Sierra :: 2006 - Headlights Fluctuating When Not Hitting Gas?
Feb 10, 2014
I have a 2006 sierra 5.3. This has happen twice to me now. This morning it was probably around -5 degrees out started my truck with remote start and it started fine. After running for 15 mins I got in it to go to work. When went to pull out of the driveway I noticed when hitting the gas my headlights getting brighter and then dimmer when not hitting the gas. When I looked at voltmeter gauge and when not pressing the accelerator it was about 12. When hitting accelerator it would go up to 14. It did this for about 15 mins or so stopping and going.
On the way home today it didn't fluctuate. When I got home I tested the alternator with volt meter. It was reading 15.3 volts. From what I read on the internet it says the fluctuation is normal and so is the 15.3 volts. I read 2005 trucks and up have regulated voltage control. Even talks about the gauge fluctuating in the owners manual. I had the battery and alternator tested both tested good. Alternator does have a little noise in it when spinning the pulley by hand. I'm just not convinced that 15.3 volts is normal. The battery isn't original it had been replaced by the previous owner.? Is my alternator possibly going out.

Ok so my 2002 gti is having some boost problems... Instead of hitting boost consistently the boost is fluctuating for example hitting 12 psi then 15 psi and it just hits and bounces back to 0. what could be problem I was thinking bad downpipe, bad waste gate, or bad n75 valve.

I noticed last night on my way home from work that my headlights were flickering. I looked and also noticed my amp meter was also fluxuating. The car seemed to be running fine asside from the lights kept flickering. It did not make a difference what RPMs I was running, or even if the car was moving. My 2000 Bonneville has the original alternator and 181k on her...

1999 GMC Sierra - 2wd
Truck belongs to a co-workers son so I might not have all the info I need. Just within the last couple of days - he's driving at night and the headlights cut off. Pulls over and waits a bit - restarts - lights work for 1/2-1 mile then cut off again. He has changed the headlight relay switch.
No DRL but does have automatic headlights. First noted this Tuesday night and the weather since Tuesday has been either rainy or foggy. He had higher intensity "blue" bulbs installed but has swapped them to regular bulbs and the problem continues.

How I can turn off my automatic headlights on my 99 Sierra? I do not want them to come on automatically when it gets dark. I would like to do it manually. The dealership said they cannot do it for liability reasons. How can I get them so I can manually turn them on and off?

Ok so I have I 2007 hyundai accent with a weird problem. When the car is in normal operating temperature (180-210) and stopped at a stoplight or stop sign the car will have a fluctuating idle. This problem only happens when the car is at idle and with the heat or air conditioning on. With the heat and the air condition off the car will do it once in a great while. Things I have done so far. Replace the pcv valve clean the egr. To me it sounds like a voltage problem like the car is having too much load at idle. But I am unsure. Took it to a mechanic the other day and he couldn't replicate the problem.

A friend of mine has had this 2000 Sierra since new. It has just over 100K and never had any cooling issues before. Last week when it was about 10 below zero she drove it home and it overheated and pumped a couple quarts of antifreeze overboard.
She refilled it the next day and it was fine but got it looked at by a local independent mechanic. I had told her that it was likely a sticky thermostat and it ought to be changed out anyways due to its age. The mechanic thought I was wrong and that she had driven it off to quickly in the super cold weather.

2006 GMC Sierra 1500 crew cab 4x4. Bought it with a 3 inch body lift. 2 years ago I put on a 3 inch suspension lift (blocks in the rear and torsion keys in front). Tires were getting worn out and truck had a hop to it, so brand new tires (33's) 4,000 miles ago.
Since putting on new tires I have replaced:
-both front rotors (they were warped)
-front brake pads
-pitman arm
-idler arm
Still have the hop. Cant feel it in the steering wheel and very little in the seat. Mostly in the floor boards. Hop starts at 50 mph and stops at 70 mph.
Front end is stiff since putting on new torsion keys in front.
Have had new tires rotated once and balanced twice with no change.
I know my rear shocks are shot and my front shocks are almost done.

About 2 months ago my 2008 accent 3 dr hatchback started to do what i can only explain as a hiccup while idling and also when first hitting the gas. But I didn't have. Check engine light on. So I changed the air filter and put techron a fuel injector cleaner in it stopped until last night so I am replacing the spark plugs. Is there any thing else i should look in to replacing?

I have a 2006 GMC Sierra z71 has 159,000 miles on it. I've already changed the front hub bearings and the tires are brand new. Brakes are in good shape as well. I also had someone check the front differential bearings too. Said the front diff was good. The noise starts at about 50-55 and keeps getting louder with speed. The noise is similar to a hub bearing noise. When you let off the throttle the noise is more pronounced then when on the throttle. I'm thinking it's te cv axles. The cv boots don't have any tears in them and I have no clicking noise. But I've also heard that cv axles can make this noise. Also the noise seems to change when I hit bumps. that's also why I'm thinking cv axles. Because cv axles are the only thing that move with the suspension and also rotate.

I have a 2006 GMC Sierra with 90,000 miles and a 5.3 engine. Never any issues but I've noticed that when I start the truck up the electric auxiliary fan comes on immediately. This is when the truck is cold and the fan should not be needed. Never had any issues with it overheating or anything. Is this just a sensor gone out or something or is it normal? If it is a sensor which one is it and where would it be located?

My 2006 V6 Camry XLE feels like there is a delay between hitting the pedal and the car accelerating. I also notice it bucks (changes gears at the wrong time) occasionally when pressing the pedal than backing off of it a little. The hesitation has always been there but lately its been really bothering me because I drove someone else car (Hyundai Sonata 4 cylinder )and felt how smooth it accelerated and how responsive it was at lower speeds. I know this car has drive by wire which probably has something to do with the problem. How to alleviate this issue? I don't think there's anything mechanically wrong.

2006 with 110K. I did a search for rattles. My question is do these struts have bushings or shims that wear out over time. Going down the road car is nice and quiet. Hit some bumps and it sounds like it is coming apart.

I have a 70,000 mile touring SE which at low speeds( less than 20) has a rattling/clunking noise when hitting any small bump. Can not hear anything at higher speeds. Steers well noise could be coming from both sides. They did replace my transmission at 40,000 miles. Car does not bounce when pushing on it like a strut is bad.

I have a 2006 gmc sierra, 4x4, 1/2 ton, has 155,000 miles on it. I recently changed both front hubs on my truck. They didn't have any play in them just noise. I had one new front hub that was leaking grease out of the rear seal. I took that one back off and got a new one. Must have had a bad rear seal. Now I'm getting a front end vibration at highway speeds. Between 70-75mph. It gets worse when turning left when highway turns. It goes completely away when turning right at highway speeds. It doesn't shake in the steering wheel. Feels like its coming from the left front area or left front tire. More in the floor boards. So i rotated my tires, and its not as bad but still is there in the same spot. I've checked everything.
Cv axles have no tears in the boots and aren't spinning out any grease. I turn the steering back and fourth while the truck was on the ground and I didn't notice any play in any of the front end components. The only thing I did notice was the passenger side inner tie rod boot had a bunch of grease built up on it. But the boot was actually full. Could one of the bad wheel bearings caused something else to go bad? Warped rotor? Truck doesn't shake or vibrate when braking either.

If I said that I can "feel the road" in my gas pedal and steering, what this means (like every bump etc...). If so where would I start to look to try to fix this issue or how to lessen the feel. Also is there anyway to make the steering wheel more stiff it shakes while hitting a considerable speed.

So the check system light went on after driving 30 minutes then hitting traffic. Would it be possible that it's the TPMS telling me the tire pressure is low? The tires i have are 245 30 and 285 25..the psi on both tires on the driver side are at 30 and the passenger side are both at 33. could that be the reason? What the recommended PSI is for tires that size?

Not so much hitting pot holes but hitting dips in road I get a noise up front like hard plastic cracked and hitting edges, had the front end checked all fine and he changed the sway bar links said sloppy, still noise, I went under found the front pipe bracket broken so I clamped that, still noise-could it be the strut boot? Doesn't seem to be the shock bushing they seem tight but can not really see them and the upper shock part seems secure. 2011 accent 60k miles. Where I could look next? The plastic around the wheel well is cracked but I don't think all that noise is coming from that, but the next warm dry day I will try to snug that up.

I have a Gs 430 - 2006. After hitting bumps in the highway big or small it seems like my dash or suspension squeaks inside the car. Since I can hear it so clearly I'm leaning towards its the dash or something behind the dash, It seems to be coming from the drivers side.What could it be?
