View 4 RepliesI 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.
Been doing a lot of repair's on our 1994 Chevy blazer. It's a 4.3 v6. We finally got her running and now it seems like it can't take high speeds for very long without over heating and eventually smoking some. Had to bypass heater core, it's clogged. That worked with temp. Also replaced radiator and cap. Replaced both heads, took thermostat out. That worked with temp too. It has a new water pump, new exhaust manifolds, has good spark plugs, oil changed and oil filter. Kind of at a loss.
View 16 RepliesOur 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.
2002 Chev trailblazer, I have had the throttle body cleaned.... Sometimes after short stops, my vehicle will not crank, some times I have to step on the gas several times and it will finally crank, it sets no codes, no check engine lights come on. If it sits overnight, or for more than 20 minutes it cranks right up.

View 3 RepliesI got my blazer look at and here what they come up with so far. Transmission fluid is discolored. Transmission shifts late between 3rd and 4th at 52 mph. Transmission slips between 2nd and 3rd gears at 32 mph. Lock up 41-43 mph in and out. I never told them this but I change the transmission fluid about a week before i took it there and when I check the fluid it was nice and clean and not burned like he said it was. He said most likely it internal damage.for them to take a look in side to see what is wrong with cost me 400.00 and I said no.

View 2 Repliesmy 97 chevy blazer has a lot of cranking first start in the day. I changed the rotor and distributor cap but I don't smell any fuel then all fo asudden it will start. I am wondering is it a fuel relay problem, a fuel filter, or some sort of sensor. when it does start it is very smooth running no shaking or hesitation full of power for the rest of the day starts and stops erands . is it worth buying a plug in code gadget and will this problem show up as a code.
View 4 RepliesMy wife bought a 2003 Chevy Blazer LS 4WD recently and it's nearly perfect except for one quirk. While driving on straight and level roads it will suddenly go left a little and then back to the right. I bought 4 new tires for her and had an alignment done at the same time. The technician allowed me to watch the alignment while in progress. All 4 wheels were connected to a computer and the screen showed the rear was in perfect alignment. The driver's side front was also in perfect alignment but the passenger side was out. That side was aligned and the technician assured me there was no other problems.
On the drive home....it still wandered right then left then repeated every few seconds. I took the Blazer back this morning and they repeated the alignment but it still has the same problem. I have an appointment for Monday morning at a different alignment shop. What might be going on? Everything seems to be tight on the suspension. The vehicle looks brand new inside and out and runs great. It only has 117K on the clock and looks totally original underneath.
A co-worker has an issue with a 2002 Chevy Blazer where the oil is mixed with the coolant. My understanding is the usual causes of this are blown head gasket, cracked cylinder head, or cracked engine block. If the cause is a head gasket, they'll probably fix it. Cracked cylinder head makes fixing it iffy. A cracked engine block probably means junking the vehicle. Is there a fairly inexpensive way of determining the cause?

View 1 RepliesMy 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?
View 7 RepliesI have a 94 chevy blazer. I purchased it not running. I replaced the fuel tank, fuel pump, fuel filter and plugs. The car ran fine for a couple of weeks. Then it started choking out after putting into drive. i tried to give it gas while shifting and it still died. I replaced the fuel regulator, dist. cap, fuel filter again, and the ECM. It now chokes out while in park. What am I missing?
View 3 RepliesI 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.
Went under truck and saw fluid. Squeezed the rubber boot and fluid poured out does that mean the steering rack needs to be replaced? If so how hard is it to replace?
View 4 RepliesI 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!
