Sierra :: 1999 GMC / 2WD - Truck Headlights Cut Off While Driving
Jan 10, 2013
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.

I have a little problem with my 1999 f250 7.3 power stroke diesel. Every once in awhile, while driving the truck would die completely but i switch it into neutral and started right up. What could be the problem?

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?

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 The battery isn't original it had been replaced by the previous owner.?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.

On my way to work today it was raining so I turned my head lights on. All the dash warning lights came on and my truck had zero throttle response. I quickly turned my lights off. The truck went right back to normal. I turned my lights back on and nothing happened.

Smoked headlights on a magnetic grey 11-16 superduty. Looking for a pic. I saw a blue flame f150 today at the car wash with smoked headlights. He had someone smoke the factory head lights and tail lights, not smoked aftermarkets, and they looked great. I found out where he got them.

I bought a 99 f350, that already had HID's in it, i found out i was running the wrong batters (weren't 800 cold crank) I just had to replace the alternator. Ever since the new alternator when i turn on my headlights my truck shuts off. IT fried my IDM and i just put a new IDM and 2 new batteries in it today. Thinking i had fixed the problem i drove around no issues, finally i was leaving someones house and turned on my lights, and truck shuts off!!! It restarts but now im trowing a code!!!! im guessing the HIDs are wired wrong and that's why its shutting down the truck but OEM IDM from ford is 1300$!!!!! brand new one installed today,

I have a 1992 GMC step side, short bed, 350 engine, Sierra, auto trans, factory air, factory exhaust, power steering.......
Three years ago the fuel pump went out. I have to work alone so I lowered the tank after draining and went through a lot of agony with floor jacks, supports, etc. but finally got the job done in 3 days.
The replacement was a Bosch fuel pump.
It went out today while I was at Sams stores. I got a pull home and it is in my driveway.
It started up once I got it home, but that is what it did the last time it went out, 3 years ago.
Question...should I check the ground first to make sure it is not getting intermittant ground or just do the job with a new pump?
Also, can I do this job by raising or sliding the bed after I unbolt it? I have heard war stories but no actual person that has done it.
Also, when moving the bed either up or sliding it back, isn't there a concern about wires that go to the tail lights?
I cannot afford the 500 dollar shop fee to have it towed and fixed.

1985 GMC Sierra 2 wheel drive. Truck sets lower on drivers side about 1 or 1.5 inches. Very noticable. Put new coil springs in front and 4 new shocks on. Back springs are original heavy duty with six leafs. Nothing noticable. don't know what to do. This truck is all factory original.

I have a 97 Sierra with a 4.3 in it. The truck has 236,000 miles on it.
The truck ran great up to a couple days ago. My father in law was driving it and he said he started it, put in gear to drive off and it just died. It will not start now. The fuel pump is priming when you first turn the key. I haven't had a chance to look at it, but my FIL said he pulled a couple plug wires and there is no spark.
I've been doing some reading online and I've seen bad crank sensor as a good possibility. Is this a common problem? I'm not wanting to sink a ton of money into this truck with its mileage.

When my truck is slowing down my manual transmission makes a knocking sound, but does not make the sound when accelerating. What could be the problem?

Son's 2000 GMC Sierra, 200000 miles, 4.8L engine, automatic transmission and 4WD. Was driving home from a trip to the store - heard a "violent popping noise" on the passenger side and the truck simply slowed to a stop. Engine running fine, all sounds fine while idling. When we put it into any gear, I can "feel" it go into gear but the truck doesn't move forward or back. Just changed differential, transfer case, and transmission fluids about two months ago.

As the title says, the 2001GMC Sierra 2500 truck has been acting up lately. This usually happens when the truck is in motion, doing about 40 mph or so. It will quit, i have to pull over to the side of the road. And it usually starts right back up. This has been going on ever since I had the fuel pump replaced about 3 months ago or so. It was doing it once every two weeks, then once a week, then once every other day. Then it stranded me at the store before xmas. Right off I thought it is the fuel pump being intermittent, and just getting worse. I am not so sure though.
My mechanic will warranty it, but would rather not have to if its not the problem. He would rather have the truck die and stay dead, and test out things from there. There in lies the problem. The pump works, I can hear it power up, and if the truck stalls, it starts right back up. One more thing. If it does not start immediately, and I don't drain the battery, it will start in an hour or less. It will not just stop working for an extended period of time. There is no check engine light on btw. No codes come up while its on the computer. I don't drive it except in the driveway to plow, for fear of having to have it towed. It works though as i have a really long driveway.

I recently started having problems with my 98 GMC Sierra c1500. I'll be driving and all the sudden it will jerk as if it's shifted from 5th to 1st gear, but the revs don't go up, they drop to about 600 like it is about to die and then it go back to normal revs. It only does this while I'm on the gas and very rarely at idle. I don't know if it could be the transmission or something is blocking fuel from the engine.

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.

This truck has 180km on it and runs fine except as of lately i have developed a surge while at constant speed. When i step on the gas it does not seem to happen.....it only happens when I reach a constant speed. The odd time it will surge at idle and the engine will rev up and down on its own also. When at highway speed it seems to not do this. The truck never dies completely....just surges slightly.

2000 GMC Sierra, just over 200k, 4.8L, 4WD. Son was driving and the rear differential seemed to sieze up. Internal casing was destroyed, so got a replacement. Matched the size using the code inside the glove box (something similar to GT4 in both vehicles - it matched exactly). Attached video shows the sound that is coming from the rear of the truck. This noise happens on deceleration. Can drive at least 20MPH and let off the gas. Truck begins shaking at 45MPH. There is no feeling of loss of power or anything negative besides the sound on deceleration.
Important note, this sound was present before we changed the differential guts, and is absent when in 4WD. We only hear the sound when the truck is in 2WD.

2002 f350 ext cab. Having an issue where my lights are blinking or flashing repeatedly while driving. Or whenever really. Truck running or not. Auto light switch in any position. I can hear what I believe to be the under dash circuit breaker clicking on and off. If I turn my light switch to the on position, breaker still clicks but lights remain steady. Where to start looking? Bad wire? Bad switch?
