Since I can identify the Lights On Chime terminal, for the test, I should be able to ID the terminal for Key In Ignition Chime.
But alas, the next step in flow chart asks if Key In Ignition Chime is working. NO. So I have reached the convergent point for BOTH failures' Flow Charts, withOUT knowing what FSM screw up is. Take THAT MF'er!!! Pretty soon, we'll reach a convergent point in Flow Charts for EVERY INTERMITTENT that I have here. Resume tomorrow. Anyone following??? |

CCM pull hard job? Pffttt; try the A/C programmer.
It's ON the firewall, HIGH ABOVE THE GAS PEDAL. Everything is working now. Every screw turn, I'll have to wiggle parts, WHILE LISTENING TO CHIME, and see if I can find a loose connection............ |

Right now, I can get NO problems to manifest. EVERYthing is working perfectly.
I wiggled harnesses, STUDIED them, doesn't look so scary at all. No CHIME interruptions, NOTHING. A/C, Radio working, NO problems. I'm ready for SOMEthing - .......... A/C Programmer back in. |

Will try to re-secure some of these harnesses with plastic loom, zip ties. Maybe that will manifest SOME problem... |

A shot of A/C Programmer, for an idea of accessibility.
If yours never fails, good. If it does, you know where it is. The 'firewall' side of A/C Programmer is PAPER. It is NOT sealed against its mount. NOT liking that... Rapping with my knuckle did not interfere with chimes... |

Chime is in dash behind DIC. Rapped on Chime Module, and it started back up. DIC IS loose - knocked on it, Chime stopped..

Chime module.
I cannot figure out if it's the connector, or the Module itself. Touching the TOP Mounting tab interrupted the Chime. BARELY wiggling the Chime Harness Connector did the same thing. Either way, could Chime Circuit malfunction interfere with other circuits????????? USE CARE TO NOT PUSH THE DIC INTERFACE BACK OUT OF THE HOUSING - NOT EASY TO SNAP BACK IN !!!!!!! |

No clue Matt; all I did was grease on the 4 tabs. I can't see that grease made the difference, but I cannot argue with results ( so far here ).
I gave it a brief glance about breakdown of the module itself, but didn't see anything. Should have investigated further. Not too late tho' ---------------- The greased connections did NOT fix it. Wrap up / cleanup, Key in, rapped on chime again, it stopped. TO MAKE IT WORSE, PULLED THE KEY (NO MODULE CONTACT), THEN STUCK IN THE KEY, AND THE CHIME RE-STARTED. HOLY CRAP.......................................... |

Sticking the key on, that made chime re-start, might have induced current to 'jump' a bad connection / solder joint in the Chime Module. Again, I'm able to stop Chime, and re-start it, by knocking on it. Have to pull it, and open the Module. I can't do any damage to it, in its condition... |

Put in the chime logic board, and beat on it. Top, side, bottom, inside, outside, it would not STOP chiming. I am absolutely dumbfounded. SOMEone come up with something stupid, that's the solution. |

I HAVE been able to stop the chime by rapping on the Module.
I have NOT been able to stop it by just wiggling it on the harness. Nothing else, wiggling other harnesses interferes with it, EXCEPT working the Key in ignition... ??????????????????? |

Perhaps it is the Chime Module housing, applying pressure to one of the connection tabs, opening a soldered joint.
And this is why I can stop the Chime only when INSIDE the housing, with rapping pressure? ??? |

I'm going to put a Dremel to the 4 tab openings.
BESIDES, I CANNOT TELL THAT IT'S NOT ONE OF THE CONNECTORS, ON THE END OF THE HARNESS, TO THE CHIME MODULE. I'm convinced that pressure is applying to one or more tabs, that's breaking the connection. The logic board is held inside the housing, so it will not move out of place inside the housing... |

It appears for the moment Matt, that you are right - broken solder joint.
I opened up the opening, plugged in the chime, and it wouldn't stop with rapping. Holding my breath here.................. |

With baited breath, I say you're right.
Chime is in. Working. I CANNOT stop the Chime by rapping on it with my fingers, whereas I COULD before. Got one Watched on eBay for $20. Re-assembly continues, looking for another Short / Open. I WAS able to make tranny selector lights blink, sometime past in this thread, so there could be another short / open. LCD Fuse feeds Chime, SO BROKEN JOINT IN CHIME LOGIC BOARD WOULD SURELY MAKE LCD FLICKER. |

Already got one Watched on eBay there Matt. Just have to MAKE SURE that there's breakage in it. It's what diags is all about - ruling OUT stuff.
Most of Chime Circuit is above, post 123. FSM Section 8A-76-0 Electricity flow is like water. Interrupt it in one place, and water flow is changed EVERYwhere else. An LCD Light will show it. |

CCM out of the way. The 2 tap connectors, added by the shop that put in the auto, are loose.
I could have done the auto, and saved myself $5.5k here... The horn might be out, since I pulled the left horn, of 2, and left an open connector. And we are having FUN. Get out, cam card out, edit pic, post, and back in. SH*&.......................... |

The speed shop [pffttt] that did my auto install did a great job mixing up all the dash / console screws and bolts.
$9k. That was a $6k job, and they did a $3k job. Stay away from MAYHEM Motorsports. Mayhem? Yup. It did almost NO GOOD, to label and tape dash screws. Thankfully I have the GM Manual for ALL C4 parts. What a nightmare. (Andy / Matt; I can try to upload those Manuals of C4 Parts - they're an invaluable resource - 22 .pdf's, 425 megs) I spent :45 waxing the I/C glass. I was able to hide some scratches here... |
