I have 96 blazer that recently threw a rod bearing. In my hunt for a used 4.3, I stumbled upon my coworkers motor out of a 99 bravada. He's givin it up for a great price and I know it was well serviced, it was pulled for a 350 swap. Does anyone know if this motor will work in my 96????

The 99-01 had the secondary air injection so you can use it but need to change the exhaust manifolds or simply plug the place where it comes out - depends if smog state and they would really have to get down in there to see it. The computer may be different also so check with the GM dealer on that with your VIN - i.e. is a 96 and 99 the same? Think some of the sensors were also changed so some inputs also may have been. Wrecking yards have a cross ref book that also tells the answer.

Your wiper motor maybe fine or burnt out by now but putting a new one only going to burn out again GM's Blazer and Jimmy have that problem the mechanical parts under the cowl where the wiper arms screwed to is seized you have to remove the cowl that black plastic piece below the windshield, removed the wiper arm first then remove the two end piece then the middle piece then loose the nuts at the base where the wiper arms was and that center nut on the motor also remove the wiper motor carefully remove the mechanism spray some W-D40 on each joint then oil each joint, then work it with your hand till it free up, if the wiper motor is still good every thing will be fine but some times when the mechanical parts seized up like that it puts pressure on the motor and burns it out, if you are going to put a new motor make sure you do what I told you and you'll be OK,GM have a good plan but ashamed to let the Japanese refined it, water keep wetting the mechanism under the cowl and that’s why after a while it seized up, my wife paid over six hundred dollars to fix our truck because I wasn't here and it stops before I get home I had to buy a new motor again and do all that I told you and now the wipers are OK, and it only cost me $87 dollars for the new motor at AutoZone, I hope you can do this yourself the dealer makes more money repairing these trucks than what they made selling them, and if you have rear wiper take that out and do the same thing too don't Waite for it to stop.
Hope I was of help.

My SECURETY LIGHT comes on sometimes when I am driving, which let me know the pass lock system not working properly some time the truck start up and shuts off immediately no matter how much times you starts it, it just shuts off like its out of gas then after about ten minutes it starts and every thing is fine, when I check the manual I've learned that if this happens you are to Waite ten minutes then start and it will start but I can't take this anymore does any one have any remedy for this situation, I don't want to go to the dealer, most time that’s just waste of money. Thanks

Need a body code scanner to look at and they are the $200 plus range but the dealer is the best for this as they have seen them. Usually its in the column either the hall effect sensor on the tumbler or the wiring and connector (called the ignition switch - don't ask why) so a pain to fix either way. Good luck because at some point it may fail completely and not restart - have to fix it soon. Was the dash pulled for a heater core recently cause that may be the reason as the connector was not firmly reseated.

Thanks I do that yes there seems to be an AC leak under the dash and the technician tried to find it, so I think that’s what causes the problem I'll just take it to the dealer as you said thanks again.

Sounds just like my 1998 Jimmy 4dr. How well does your rear wiper work ? mine hasn't worked for years , Power mirrors are nice but in true GMC fashion , they quit working a long time ago !! The fi rst and only time I tried to recline my seats the levers broke off , now i just use a screw driver . what kind of crap is GM trying to sell ??

now it works with a loud screechy noise, my power mirrors don't works any more, my seats don't recline anymore cause the levers are all broken, there's a loud cracking sound at the front end when I turn the steering fully to left or right, GM really sucks.

Can a 1995 chevy blazer be chipped or does it have to be tuned with a tuner?

Good question and not sure but the Jet catalog should tell you - if its ODB II then Jet has the add on module. Those juts fool the temp so run richer thus more HP but would have to say mpg drop. The turners are like $300 plus and can override the top speed limiter (why cause at 93 the things will be shaking), reset tire size/odometer, and shift points. For a stock vehicle spend your money on quality ignition parts and filters!
