Chevy Blazer GMC Jimmy Electrical Problems

  • Well, I took out the starter that I just put in to have it tested. It was bench-tested @ 95 amps, which was the max that it should put out. But, I did walk out with a starter/ignition swtich (which, by the way is a pain in the [non-permissible content removed] to put in 'cause it's mounted right on the steering column). After installing everything, the truck seem to kick over just fine. I tried it a couple of times, then decided to put the truck back together. After all that was done, I tried to start it again, and it was like it was dead as a freaking doorknob. So, now I'm scratching my head so much that I think I hit bone.

    Regardless what the stater test revealed, I feel like your starter is worn out. I did not think people tested starters anymore, they just replace them as a routine procedure after 100,000 miles if there are starting problems. Before replacing the starter, make sure the battery, the cables and the cable connections are good. You need to replace the starter and starter solenoid with a remanufacturered starter and a new starter solenoid.

    NAPA has the best remanufactured products. NAPA remanufactured starters cost from $100 + $29 core deposit for a standard starter to $144 + $60 core deposit for a premium remanufactured starter. Both starters include a new solenoid. Replace the old worn out starter and you will be amazed how well the engine starts.

    As you found out, there was nothing wrong with your original ignition switch. Ignition switches seldom fail. I have never had to replace a ignition switch after 50 years keeping my old cars in good condition.

  • all the fuse is new is a 1992 chevy blazer all the bult is new i try everyting ground cable new what next? hablo español
  • I have a 96 blazer that when you use the hazard lights all the tail lights flash even the backing lights the same as when I use the brakes at first it was just blowing fuses when I had the lights on and then turned now there's no turn signal at all and Ive checked all the connections to the lights but when I do use the braking or hazard lights everything else dims its almost like there's a short somewhere but Ive checked and replaced almost everything except the multifunction switch which I don't think would be the problem cause its my brake lights too and it was blowing fuses and I'm totally at a lost here and don't know what to do except replace that switch but don't want to unless I'm sure that's the problem....any help would be greatly appreciated.
  • Okay I have a 1999 Blazer LS 4x4 4 door got about 118,000 miles now. About two years ago the throttle position sensor went bad or became out of adjustment. At the time my job was kind of hit and miss so I just unplugged the sensor. Everything still runs fine. Since then I have lost my job and been through a few others thanks to the economy and have not replaced it. About six months ago the right (passengers side) headlight went out. No big thing but before I had the chance to replace the bulb it came back on. For the past several months now some days it works some days it doesn't. Recently it quit all together. I also noticed my tag lights not working. My over head light stays on unless I push the over ride button on the dash. Today I replaced both the high and low beam bulbs in the head light and the tag light bulbs. Tag light still does not work and when high beam is selected the whole light goes out. Tested all bulbs they are good. Checked fuses they are good. I am loosing hair here. Have looked at all the wires I can get to to see if any chaffing did not see any. Break lights and turn signals work fine. Cruise works. Don't really care about dome light only mention incase they are somehow related.
  • General Motors issued a recall on the windshield wiper problem. It takes them
    about 20 minutes to do the recall. Solder on the printed circut board would crack thus
    leaving them inoperable. I know this because it happened to me. There was no problem scheduling the vehicle for the recall because they are able to do it very
    quik.

    I have an '89 full size Chevy Blazer that does not have any power going to the ignition. When the key is turned nothing happens. The battery is fully charged and I have power going to the alternator and starter. I have checked all the fuses in the fuse box and the inline fuses that I have been able to find. I am curious if power needs to be coming out of the starter solenoid or where else I could check to see if there is a break in the power. Any help would be greatly appreciated.

    Your starter may have 3 leads on it. It may have 2. The large lead is direct from the battery. Only when the ignition switch is in the start or run position,you should have battery voltage to the small one(ones).Power to one small one makes the solenoid
    engage the starter drive gear which cranks the engine. One of the other small wires supply power to the ignition thus making the engine fire when the ignition switch is released. Of course to test the starter on the vehicle you'll have to have someone to help you.Use a voltmeter or a old 12volt bulb and socket you may have laying around. I use a side marker light and 194 bulb for this.Make sure the vehicle is in neuteral or park also. If there is no one to help,chock the wheels,turn the ignition on run. Get under vehicle with a screwdriver and bridge the solenoid using the large battery wire and the small wire on the solenoid. the engine should crank.If you get no results,start checking for a break in voltage between the ignition switch and the starter.Let me know what happens and I have a couple more things to add that may help.

    I have a 2000 Jimmy, and today when I put on my turn signal, the daytime running lights turned off. It didn't matter which turn signal it was. Either one made the lights turn off. My regular head lights stay on when the signal is on. PLEASE HELP!!
  • Pretty sure they're designed that way. I know my 2001 Jimmy does the same thing. I always assumed the DRLs turned off so the signals were more visible to oncoming traffic. Headlamps don't go off when you signal for obvious reasons.

    As long as they turn back on when the signal goes off, you're fine.

    But I have a 2002 chevy cavalier, and they don't turn off when i signal. I could of swore they never turned off before this. Besides, I've never noticed it on any other jimmy or blazer I've seen.

    On my '02 and '99 Blazers the DRL stay on at all times unless the headlights come on with darkness.
  • tiffs26tiffs26 Posts: 6
    Not sure. I found another forum that said this is normal. I'm gonna call a GMC dealer tomorrow and find out if it's supposed to do this.
  • tiffs26tiffs26 Posts: 6
    I talked to a GMC dealership and they said the DRL are supposed to turn off when the turn signal is on. So if anyone has any question, there's your answer.

    THE RUNNING LAMPS ONLY GO OFF WHEN THE ENGINE IS TURNED OFF.
    THEY ARE SUPPOSED TO STAY ON AS LONG AS THE CAR IS RUNNING.
    IF YOU PUT ON THE EMERGENCY BRAKE, THEY WILL TURN OFF. I OFTEN
    PUSH MY E-BRAKE ONE CLICK TO TURN THEM OFF WHILE DRIVING.
    BELIEVE IT OR NOT, THE MULTI-FUNCTION SWITCH PROBABLY NEEDS REPLACED. I HAD NO BRAKE LIGHTS,OR SIGNALS. A LOT OF STRANGE
    THINGS HAPPEN WHEN THIS SWITCH GOES BAD. ALMOST ALWAYS TO DO WITH SOMETHING WITH REAR LIGHTS. CHECK THE SWITCH. THEY COST
    ABOUT $300.00. I FOUND NEW ONES ONLINE AND PAID ONLY$32.00.GOOD LUCK!

    Like I said in my earlier statement, I talked to the service department at a GM dealer, and he said they should turn off when the blinkers are on. I think I'm gonna take his word for it.

    You may want to check the recall site. There was a recall on some part of the brake that would cause the brake to flip over.
