Chevrolet - Blazer :: 2000 - Volt Gauge Fluctuating
Nov 27, 2014
I recently had some issues getting my 2000 Blazer LS started. It would act as though the battery was dying. But if I let it set a few moments, it would start right up. Then a couple days later, I needed a jump start to get it going. I took it to my local Auto Zone to have the alternator tested because the battery was only 3 years old. (It was a 5 year battery.)
They determined that it was the battery. So I went to Walmart and bought a 700 CCA battery. And today the gauge is fluctuating again.... Considering it is cold and snowing here, heat, wipers, and rear defrost tend to be essential. But if I try to run all of them, the gauge dumps. And causes everything to bog down. I do not have any aftermarket electronics installed in the truck. And until last Thursday, this was not an issue.

I will start out with a little history of the situation. A little over three months ago my original altenator died with over 200,000 miles on it. I took it in and had it replaced (they used a refurbished altenator) and about a 1-1/2 months later is when the issue started. The headlights and dash lights will flicker and whenever they dim, the volt gauge will go down.
When the lights come back to normal brightness the volt guage will also go back to normal. All this will go on for random lengths of time as I am driving. I took the vehicle back to where I had the altenator replaced and they replaced it again under warranty. About another 1-1/2 months went by and the same thing started happening. I took it back to the same garage and this time they put in a brand new altenator. Finally about a week after this last visit to the garage the symptoms came back.

The fuel gauge on my 2000 Blazer is flipping from empty to full. (Even as I drive down the road it moves.) And nothing in between. The fuel pump was replaced about a year and a half ago. I've been told the fuel pump controls the fuel gauge. So I'm wondering if there could be a loose contection or if this is a sign the pump will go bad again.

The A/C on my hand-me-down '99 Lumina has never been outstanding, but has kept the Florida summers at bay. I recently turned it on again (I only ran it once or twice this winter) and the system was empty. I refilled it and it was empty again in 72 hours. I was hoping the seals had just dried out, but it continues to empty after several other attempts to recharge it, including adding 134a with lubricants. I added 134a with UV dye in it and the only leak I found is around the compressor clutch. I accept that the compressor probably has to go, but am puzzled by the manifold gauge readings taken when I added the last can. I just don't want to put in a new compressor and find out that wasn't the only problem.
With the system off, both High and Low sides read just under 70. (Normal Low and High side operating pressures for this car are listed at 42 and 340 respectively.) When the system is turned on, Low drops to 30 and High goes to 80 and there is no air cooling. After 30 seconds the High side slowly climbs to 200 and the Low side slowly drops to 26, with almost no air cooling. When the High side hits 200, it drops back down to 80 and the Low side goes back to 30. After 30-45 seconds it does it again and keeps repeating. The compressor clutch stays engaged the whole time. I looked in the Haynes A/C Techbook as well as online and can't find anything that resembles this description. If this is just symptomatic of a bad compressor, or is there more evil afoot? Also, while I have the system open are there any parts I should replace at the same time given the age of the system?

Our 2000 blazer LT 4.3L 4 door 4wd has 190,000 km (about 115,000 miles). 3 Button dash control. Transmission was rebuilt at 100,000 miles (main troque converter spline was shot). The 4 wd will not engage in either hi or lo.
Whether moving or not, press 4 wd lo, light stays on. but nothing happens. I cannot hear the transfer case engaging.
Had a previous problem, (withflashing light): found the vacuum hose under battery case was worn through.
I do have a service engine light on the dash. This may be unrelated, because 4wd stopped working long before service engine light came on. I have changed the Oxygen sensor, but no reset the fault yet. Where to start.

My daughter drives my old 2000 Chevy Blazer with a reconditioned transmission I paid for in Aug 2010. The new (rebuilt) transmission is now slipping. Could this be as simple as a fuse (electrical signal issue) or not having enough transmission fluid?

I have a 2000 Chevy blazer 4.3L 4 wheel drive. 4 of the 6 cylinders are misfiring and the car has completely lost power. Before this issue occurred it was running fine and the next morning when I went to start it the car was turning over and wouldn't start. My dad and uncle believe it's a distributor or computer issue but I would like other opinions about this issue.....

During a severe thunder storm the factory alarm went off. I was unable to shut off the alarm with the key fob. The power door locks did not work either with the door switch or the key fob. I disconnected the battery and let it sit for 30 minutes.
After I reconnected the battery the door locks worked using the key fob or door switch. I took it for a drive with no further problems. About 10 minutes later the alarm went off again. I could hear the door lock solenoids attempting to lock/unlock the doors and there was a clicking under the dash. I disconnected the battery again, after the battery was reconnected the power door locks were still not working. The truck starts up and runs normal, everything seems to work except for the door lock?
I checked the PW fuse, it was fine. The battery is fully charged at 12.6V. I've disconnected the battery and will have another look at it tomorrow. There was nothing useful in the Owner's Manual and the resync procedure did not work.
Update: Before driving to work this morning, I cleaned the positive and negative terminals. The locks worked and the truck ran normally during the 30 min drive to work. After reading the Owner's manual closely, I discovered the Theft Deterrent System can be disarmed by locking the car with the doors closed. The system is armed by locking the doors with a door open, i.e. pressing the lock switch when exiting the vehicle.
No further problems with the alarm or the door locks whether the Theft Deterrent System is armed or disarmed. Hopefully leaving the battery disconnected overnight was the fix.

I have a 2000 Chevy Blazer with about 180,000 miles on it. It has been running fine, then a few weeks ago we got gas at a small little station we had never been to. The day after it started cutting out. We took it to the shop and they put a new catalytic converter on it. They said it also needed a new water pump and something with oil seals, so we went ahead and did that. It drove fine for a while, then the next time we filled up with gas it started cutting out and completely died. They put a new fuel filter, spark plugs and wires and distributor cap, basically gave it a good tune up. It's been driving fine. We filled it up and with in a few miles it start stuttering. At the stop light it rattled but kept going. drove it another 3 miles and it stuttered again. We are out of money and at our wits end!

I have a 2000 Chevy Blazer and the front grill is faded and yellow. I drove to a reputable body shop and the guy there told me that this type of plastic cannot be sanded or painted because will only fade again. He told me my only option was to buy a new or aftermarket grill which ranges from $360 to $450. Is there anything I can apply to the grill that will return it to its original black finish?

The cruise control on my 2000 Blazer LS 4X4 is not working. I just changed the multi-function switch and still nothing. I looked at the throttle cables and they seem to be fine. All the fuses are good as well.

2000 Chevy Blazer 4.3 (automatic) - When I bought it used, it shifted fine, has no issues other than the transfer case wouldn't engage every time. A few months later my overhead console display lights went out, then all the dash lights such as engine, 4x4, the gauges started lighting up and acting weird randomly, then a week later the truck started shifting funny.
Now 90% of the time, the truck won't start in 1st gear, it starts in 2nd, then while accelerating up to 30-35mph it will shift up way too soon and bog down, then shit back down to 2nd, then shift up again, and continue until it hits 30-35, then it fails to shift into overdrive. Also when coming to a stop, it kicks down a gear (into 2nd I assume) pretty hard and clanks pretty loud around 2mph just before a complete stop.
Weird thing is every once in awhile, it will go away and shift normal but the engine light is usually lit up during normal shifting.Could it be the ECM causing all these weird things?

2000 Blazer 4wd, automatic, 122000 miles
In the last couple of weeks, if the Blazer isn't driven for 3 or more days, there is a slight knocking noise for 15 to 20 seconds after start up. Oil level and pressure are fine. I'm guessing it's the lifters.....

My gas gauge is moving up and down like when I start up the car the gas indicator will go down to the middle when my gas is full. My car is a 2003 toyota camry.

When I give my car some gas my boost gauge fluctuates a lot and doesn't hold, I have an OEM piston style dv revision d I believe, and I have a catch can and also a blow off valve, and I'm stage 2. I was thinking of getting an awe diverter valve?

My brother has a '92 K1500 5.7L in which he had a leaking water pump. He replaced it with an Autozone unit. After replacing the pump, he now states he is experiencing fluctuating temperatures on the gauge. He has little heat at the heater, even after letting the truck idle and after driving it. This was not a problem prior to replacing the water pump. He has put approximately 200 miles on since the replacement and it has been about 2 weeks since he replaced it. He believes he has all the air out of the system, as he has checked the overflow container and radiator several times and the coolant level has not gone down.
This now "suddenly" appears after the pump replacement, we are thinking it is not the temperature gauge sensor or bad thermostat. We are thinking possibly still air in the system or water pump cavitation.

Have a problem with the coolant gauge on their Passat? The temperature gauge on my 02 Passat sometimes reads normal (190) when I am driving and then all of a sudden it will drop back to 90. My first guess was the sending unit, but the dealer says it might be the gauge cluster too. I would think that if it was the gauge cluster the other gauges would act up too. ?

So today we were driving back home and the oil gauge start fluctuating rapidly. However it would only fluctuate when the engine speed was slow, like when you are at an idle in gear. Once I gave it some throttle the needle came back to normal. Also while making a turn the needle stayed steady as well, which made me think that it isn't a low level situation,(plus I did verify the oil level once I came to a stop).
I keep reading about oil pressure sending units going bad. I just so happen to an extra aftermarket sending unit and gauge from summit racing laying around, so I'll hook that up tomorrow and see about what the pressure actually is at idle. I hope that it is just a small problem. Whats the pressure supposed to be for the 4.0 OHV at idle anyway.

my 03 ranger 4.0l was working properly and all of a sudden I am having an issue. The battery light is on, and the volt gauge is just above L. With my multi-meter I am showing 14 volts on the output stud on the alternator, and 13.5 volts at the battery while idling. When I turn the lights/fan on I show minimal draw at the battery. Not sure if these are good checks but I figured a good place to start. Where/what should I begin checking?

My son recently bought a 2012 GLS. The temp gauge was fluctuating and I noticed the overflow was really low. I added coolant and warmed the car up with no change. After it cooled a little, I cracked the radiator cap and heard bubbling air. Upon complete removal of the cap, I saw no fluid, however, the cap is above the radiator where the hoses connect. I added coolant directly to this opening until I could see it. Closed everything up and warmed up the car. Temp gauge is now steady 1 mark below half way. The question is, did I add enough coolant? and should I see coolant inside the radiator cap when the vehicle is cold?

I have a 1998 Jeep Cherokee L6 4.0 Liter automatic with 223,000 miles.
The oil pressure usually runs around 1/8-1/4 when driving around town and now I am getting temperature spikes. I had the coolant and water pump replaced last fall when I was having similar idling issues then. My coolant isn't a perfect green color--it is a little bit grey, but it is full. I cleaned the entire throttle body last January, cleaned the IAC today, and redid the NSS this week (not that this probably matters, just being thorough in my explanation).
It seems to happen worst on hot days (of course) when idling in traffic for a few minutes and makes the air conditioned air run warmer than it should.
Is this a busted radiator? The mechanic said I did not have a leak when I had him check last week.
