Bought a 96 Blazer ran good for 2 months, then it started messing up. The engine idles very high most of the time, but at times won't idle at all. Checked engine codes said mass air flow sensor. Changed it, ran good for 2 weeks then started doing the same thing. Codes said EGR valve. Did that, ran good for a week then started doing the same thing.

We've replaced TPS, map sensor, IAC valve, 6 fuel injectors with fuel pressure regulator, vacuum hoses and PCV valve. It still idles very rough and high rpm, but sometimes it will run great and idle fine.

Whatever the problem is its not consistent. I'm getting ready to replace the PCM module. When all else fails, replace the computer. Maybe then the air conditioner will work.

My husband works for GM... I own a 95 Blazer 4WD. Love it. However, the ABS seems to take over at the most inopportune times. Especially going down hill and having to brake. Does not feel like it will stop. Took it in to a local mechanic and they hooked it up to the computer. Running and in park it registered moving at 60 mph. So we disconnected the ABS and they say it will cost about 600 to get it fixed. Anyone else with this problem? Is it the ABS or is it a speed sensor and does that have something to do with the braking system?

I own a 95 Chevy Blazer, the blinkers don't work. Anyone have this problem? I have replace all the bulbs and have put in 4 fuses? They think it's a wire short but can't find it.

Also didn't start last night but started up fine this morning. Now doesn't start again. It fires just doesn't turn over. They are thinking possibly the fuel pump? Does anyone know about a wire/plug under the drivers side carpet that can short out and cause the fuel pump to not always fire correctly? Has anyone replace the fuel pump themselves? Is it difficult? Is it located in the fuel tank?

I have owned a 95 Blazer for 3 years now. Problems, problems, problems, and even more.

Repaired transfer case (hole in vacuum line), alternator, starter, fuel pump, catalytic converter, ignition system, and most recently, like everyone else, a blown oil line to the oil cooler, I think I got it shut off before any serious engine damage.

Working space is absolutely terrible, 2 foot extension with a swivel on a 1/4 inch ratched to remove lugs on starter terminals. Chevy really messed up this one.

Disgusted in PA.

I have a 95 S-10 Blazer, 4.3L with 235,000 miles on an engine that has never been opened up. I have owned this vehicle for almost 10 years and it has been a good truck. I won't begin to list the number of repairs I have made to this vehicle. I just wanted to comment on a few things...

For the person with the blinker problem, I went through that same issue a month ago. They just quite working one day and the bulbs and fuses were fine. I ended up having to replace the entire turn signal/wiper switch assembly that is attached to the steering column. The new switch ran me $430 (Parts America on-line), and I replaced it myself; so, if you have a mechanic do the work, it may be expensive. Also, with your starting problem, replace the fuel filter before you replace the fuel pump, it may just be clogged and might solve your problem. I have put two new fuel pumps in mine and it is not an easy task because you have to drop the gas tank (very difficult w/o a lift).

All in all, I have truly enjoyed my Blazer and I plan on driving it as long as she can hold out.

I have owned a 1995 Blazer since 2002. It currently has 138500 miles. My advice to anyone considering buying one is this: Buy a sledgehammer and hit yourself in the head until you come to your senses. Besides, it will cost you less to buy the sledge and you will numb up quickly. Death is slow and painful for the average 95 Blazer owner.

I am determined to spend all of my life savings in an attempt to defeat this evil monster. If I fail, I assure you that the dastardly beast will meet a cruel and untimely death (perhaps at the hands of some local H.S. kids). Thanks GM, I'm going back to Honda.

Bought a 1995 Blazer S10 with Vortec Engine in 2003. Was a great vehicle until it became a monster. Running rough and idle was a big issue. I had it scanned for codes and found that the EGR valve was stuck open, and replaced the spark plugs while I fixed the EGR that was stuck open with carbon from the exhaust gas that was going back into the intake manifold.

Ran great for about a year. Same thing happened again. Only this time after taking off the EGR, nothing was wrong, and still missing. This motor only has 58,000 miles on it, so I decided that the spark plugs was to blame. Replaced the spark plugs and still missed. I had it scanned and the only thing that the mechanic could say was that it had a misfire.

I finally took off the intake only to find out that GM had used plastic fuel lines to the poppets, that when they get clogged, caused the lines to burst open and flood the intake with gas, because the lines hold a pressure of 64psi at all times. The cost of the CMFI was around $500 large. Decided that was just too much for as old a Blazer as this. Went to pick-a-part, got one for $5.00, just replaced today and working like a charm.

If you have a Vortec, most of the time it is a carbon issue with it. Cleaning out the intake -Upper/Lower will give you better fuel mileage and help greatly. Also welding up the hole in the EGR works great, so you don't have this issue again.

Hm, just bought a 95 red apple Blazer... and based on what I've read... I'm scared as hell being this is my first car and all...

I'm having some issues with reading the fuel gauge as it fluctuates a hell of a lot (from almost E to about half a tank). Can't wait to find what easter eggs I find in this car in the future, cause it's only been 2 days since I've had the thing and it already stalled on the off ramp from the high way, could not start it on my inclined driveway (probably due to the gas, but not sure, and it says I've driven almost 250 miles I think when in actuality I've only driven it a total of a little under 100 miles since it was bought... Wish me luck guys haha :(

We have a 95 Chevy Blazer, and guess what, all the problems listed we have had. Replaced fuel pump engine etc. etc. I think GM should stand up and make some recalls.
