Ignition switch has intermittant Acessory contacts

[beendunned]

I had an interesting summer project , involving my wife's 2001 Century. She told me that the AC quits Once-in-awhile! The problem worsend to a point where it was traceable. And after determining Freon and AC system was OK. I descoverd that. Cruise was quiting at the same time! Voltage tests on the fuse (interior) panel, showed less than 1 VDC on AC1 BCM and Cruise, when in failure mode. (DISARM AIR BAGS THEY CAN HURT U BAD !!!) these all connect to the ORANGE wire coming from the Ignition switch accessory connection. Replacemenrt should be left to people who know how. (AIR BAGS---BOOM--- say no more !!) But I feel that if My wife had had a dealershilp look into it I would have a new BCM. AC controller and the origional iintermittant problem. BUT that is My opinion, with cause .

Hope this is helpful to some of you motorheads out there

My main problem was finding valid wiring diagrams, a lot of books do great on engine disassembly, but are quite lite on electrical.

My local library however was subscribed to a great online reference website and it cost me less than two bucks for printint the schematics

good luck BD
