Replying to: ryan502 (Oct 11, 2009 1:34 am) would be very very hard to diagnose. Other people should take note of this in case it may happen to them. I would not have guessed that the antanea ground would have caused your problem. I would have suggested a break in the circut insturment panel. I would have been wrong. Thank you for sharing the info with us. I will surely remember what you found for further referance. |

Replying to: ryan502 (Oct 11, 2009 1:34 am) The lighting circuit does go to the radio to give the dimming effect for the indicators. It also goes to the lights in the instrument cluster, but the turn signal indicators do not dim. Just sort of thinking out loud here, but all these lights should not be going through the antenna lead. Looking at a schematic on a 98 and later model. Shows a grounding junction with several black wires, one of which goes to the lighting circuit of the instrument cluster, and another that goes to the *stock* radio connector. This may be where you are losing your groud connection, and by connecting the ground through the antenna you are feeding back a ground through the radio lighting ground to the instrument panel. You might just look around the radio, and just to the left of the steering column (if I am remembering locations correctly) and see if you find a damaged junction/splice connector with black wires in it. A man can go crazy trying to track down the ground loops in a modern day auto electrical system! Good Luck! |

Replying to: ollie23 (Oct 18, 2009 8:04 pm) rear brakes need adjusting. After you tighten your rear shoes, your problem will go away. It's an awful feeling when the brake pedal pulsates and that awful noise you are hearing. If you follow my instructions, I am sure your problem will go away. Try it and let us know what happens. |

I have a 97 Blazer and my daughter was driving it when it just shut down....All the dash lights are out and the truck won't turn over....I checked the fuses and found 5 or 6 that did not have 12 volts...ie eng, guages, turn signals etc.....the trans would not go into neutral either, I had to lift the dust boot off and manually release the shifter to get it into neutral....troubl shooting and moving things around the dash lights come up and I can start the trk...but turn the key off and try to restart,,,,no lights again....Help....

Replying to: retsdog (Oct 25, 2009 1:19 pm) Where I live a rebuilt altinator is $150 bucks.If it is the altinator, get a new one at the parts store. It costs a little bit more but you won't have to take it back 3 or 4 times like I did with rebuilds. It's the way these GM vehicles have been since the mid 90's. Good luck and let us know if that did'nt cure your problem
