I tapped the motor and and the wipers go on and off, so thats definately the problem. I'll try to clean the card, but if that doesn't work could I replace just the card (looks like they cost about $20 - they call it a wiper motor pulse board), or do you recommend replacing the entire motor?
 
Thanks for all your help!

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.
