Normally just the card goes bad and never had to do a motor. As you will see the torx screws may be hard to reach without a bit and a 1/4" drive and add a thin bead of silicon sealer to the cover edge to seal the moisture out and gently snug the screws so you don't flex the card,

Service engine light keeps coming on and says that my tranny is stuck in 3rd gear. I have changed both cylinoids and the light still keeps coming on. I have also been having problems with getting the key out of the ignition ever since the light came on. The tranny works fine if I switch gears manually. I have changed the cylinder in the ignition and that hasn't helped either. Any suggestions of where to check now?

Known ign switch (really the ign module) in the steering column. Triggers all sorts of weird codes and problems - lucky its in the 97 only. Sorry.

Hi - did this problem ever get resolved? I am having the same issue - along with the radio & pwr. windows shutting off immediately upon turning off the key (used to have a delay). The override switch is fine, but also the drivers side wont lock when using the power lock when the car is turned on. Only when off. Help - my Chevy Dealer wants over $100 just to look at it. All fuses are OK

Thats all in the headlight switch assembly - replace and its about $55 at most stores - have to remove the dash trim to do it.

96 chevy blazer LT, need answers by piper5

my son had a 96 chevy blazer LT. today would have been 30 days of him having it. It has already been in the shop, because after having it 2and a half weeks it had to be jumped everytime you started it. Then on friday oct. 20 he and 3 friends were heading back to school for one more band practice before the game that night. as he left his friends driveway, the brakes went out, the blazer revved shut it's self down completely and went into a series of rolls. when it did land they had enough time to climb out, then it caught fire from the dash to the front end. one passenger said after the fire started, the blazer went haywire, it tried to start it's self, the headlights went off and on, and the horn went off. they were all wearing their seatbelts and thankfully came out with very minor injuries, but now noone will even answer my question as to what would cause the brakes to fail, the engine to rev and shut down, and where they rolled, it should not have rolled.
does anyone know what causes this? why are companies avoiding me?

The starting problem was normal for a 10 year old Blazer - alternator and/or battery. As to the other terrible problem I am glad that they all were OK but I was lost on the series of events. Please slowly detail and maybe someone can explain what happened. A 10 year old used vehicle has no warranty and who knows what the previous owner or owners did to the vehicle so without a complete repair/service history GM can't really do much. The NHTSA has forms to file on accidents that may provide you some help. Gas and transmission fluid will ignite and then the electrical will melt and wires will short. Need to say if 4wd or not and mileage and anything else you know plus all past repairs.

ok, i'm still shaken, but as slow as i can. here's what
happened. my son and his friends were leaving a friends house around 4pm last friday. his friends driveway is gravel that goes into asphalt. he got to the middle of the drive, applied the brakes, only instead of slowing, the blazer sped up. (There was a nurse living next to the house, and what she said, was it sounded like it just throttled all the way up.) Once the brakes went out and it sped up, it shut down on him completely. no motor, no steering, everything just locked up. when it locked up, he had no control, it hit loose gravel on the flat surface of the road shot them toward a ditch. the ditch caused the series of rollovers. when looking at where the rollovers started, if they were to roll at all, it should have been side to side maybe twice into the woods. instead it was end over end, corner to corner, then side to side. what really gets me though is from where it shut down to where the wreck started, there wasn't enough room to get that much momentum going to flip. all but 3 windows shattered. the front seats have a gap between the doors between 6 and twelve inches, which kept them away from the doors. then it caught fire. but it burned either from the back of the dash through the motor, or the motor to the back of the dash. I wish i could show a picture of what it looks like. We know the blazer malfunctioned, we just don't know what went first. But because of the fire, they cited him for careless driving. i know there where some recalls, i just don't know if any of the 6 before ever took it in, and the service department where he got it, replaced the belt and battery 2 weeks after he got it. we had no idea anything else was wrong. For me, all of this happening, and he only had it a little over 3 weeks, i don't understand. Aren't they suppossed to be checked and serviced before they put them out to sell?
