WOW, this is some scary stuff LOL.
I bought a 2000 Blazer back in Oct. 2009 and I love it! I have always been a loyal Chevy man!
There are some things about this Blazer that suck, like # 3 spark plug, as I found out after bringing it home, but I fixed that problem; I took a 1/4 socket, ground it down to fit in a 3/8 drive, 5/8 socket, and used the 1/4 drive ratchet and boom, spark plug out and new one it.
I had the clunk in the hood, but that was an easy fix for me; I took a piece of copper sheet and made a shim, problem solved LOL. I will keep my $4.80 for the spring washer LOL.
The only major problem I have had to date is the passenger side upper control arm bushings. I knew they were bad when I bought it, put it off, but finally got to it.
Every once in a while there is a drop or two of oil under it, but it's a Chevy, they bleed LOL. I did change the transmission fluid and filter, and the brakes.
I did have the drivers side window stick UP thank god! They usually quit working when they are down LOL; that was another easy fix for me, I took the motor out, took it apart and re-faced the brushes and it has been fine!, I think I saved $150.00 or so with that fix. I learned that back in 1990 with an 86 Olds I had, I had the motors replaced by the Olds dealer and I got the old motors and messed around with them, and found that the brushes go bad.
As for the hood hinge shim deal, I have a bit of an engineering background, I also maintain things, keep the oil changed and check it every few days, keep the front greased, and just because it's a truck, doesn't mean it can take anything, after all, it is just basically a car that says Blazer on it LOL.
But after all, I still love this Blazer, it drives great, although it is a tad under powered, but I can live with that. I think GM should have shoved at least a 305 under the hood LOL; maybe sometime down the road I will stuff a 327 or 350 in it hehe.
Well just my 2 cents; take care all and drive safe, and remember, if you take care of your car, your car will take care of you.
I bought a 2000 Blazer 2WD new. I have 147,000 HARD miles on it.
All of the problems (except transmission) mentioned I have had to deal with either through extended warranty or out of pocket.
The brakes, hubs and poor overall quality of the vehicle build & accessories are the major weak points. At 60,000 miles, expect things to begin failing frequently due to wear out.
The engine is solid if you can keep the rest of the vehicle from disintegrating around it! Change your transmission fluid every 50,000 miles. Get rid of the DEXCOOL ASAP and make sure to flush completely.
Don't bother cutting rotors, buy (premium) new ones all around along with new ceramic pads, and have the rotors turned true by an expert before you install them.
You can expect to replace wheel hubs every 60k or so. Make sure the ball joints get lubed during LOF service. The drive train will hold together if you take care of it.
I still have the vehicle. It was a lemon from day one due to many, many repairs under warranty. After 30,000 miles it settled down and went from Key West to Anchorage and back. It has seen severe use.
It has been a love/hate relationship with this vehicle. The 2000 was a particularly bad year from what I have experienced and heard. I would not buy a used one unless it was a steal and I knew the complete history of the vehicle. Hope some of this helps.
2000 Blazer, 4.3L V6: 273000 km and counting.
Major problems: 4 times truck wouldn't start when I turned the key:
~150000 km: dead battery (wouldn't charge - replaced).
~200000 km: electric fuel pump failed.
~250000 km: wouldn't fire in salty fog on Atlantic coast. Local garage rebuilt ignition system (had never been touched before).
~270000 km: ignition coil failed. Dealer said previuos repair had used a cheap whitebox coil.
Other problems (typical for this vehicle):
- front wheel bearings replaced 2X (1 warranty, 1 paid). No problem in last 100000 km.
- 4WD solenoid replaced once.
- hazard switch replaced.
All in all, not bad for "cheap low quality North American crap" as typically seen on auto forums. At least it has never run away uncontrollably.
Now if I could just reverse the rusting... :-(
I must say, I have read with great interest the comments on the Blazer and while I too have had some of the similar "ailments" with my truck that many others have had, I would not trade it for the world.
We bought our 2000 LT in 2001 with 18k miles on it. I have driven it for 9 years and put almost 250,000 miles on it.
I am having some problems now and did have others recently (had to have the fuel pump replaced 2 times, but it was my fault, driving it when the low fuel light was on), so can't blame the truck, just my being lazy & not stopping to put gas in it.
I am having problems now with the ABS system and am looking for another vehicle. I am keeping my Blazer though, to use as a company vehicle because it has been such a great truck for me. It has all the bells & whistles on it and none of them have ever caused me a problem. Well I take that back, the window did jump out of its track once, but I put it back & no more problems. The leather seats have lasted better than any seats I've ever had in any vehicle, they still look new & warm up nicely in the winter.
I'm hoping to put 300k miles on it before it is retired from everyday work, at which time it will proudly be used as our primary company truck for deliveries.
I, too, have had a lot of these problems.
Re: the tailgate/rear window switch where the little plastic arm breaks, I used the emergency access hole to open the tailgate so I could remove the cover panels. After that, I just removed the broken actuator arm and took some stainless steel electric fence wire and tied the solenoid shaft to the unlocking lever and it's been working fine so far. The replacement switch assembly costs about $50 at Autozone or O'Reilly's. If the wire breaks, I'll probably just get a new assembly. It'd cost about $300 to get a shop to fix it.
For a while before I took the panels off, I just tied a wire tie to the lever and let it stick through the emergency access hole to make it easier to open. You could probably tie a cord to the wire tie and run it to the front and open it that way.
But my new problem is the A/C working intermittently. The wife says (I rarely drive it) it cools fine, but will just quit cooling and blow hot air, then later it cools again. What's up with that? Any hints are greatly appreciated.
