2000 bonneville instrument guages go nuts or may work properly, a/c may come on or maybe not (fan always works, though sometimes the passenger a/c blows cold and the drivers won't), and courtesey lights may or may not come on. Replaced ECM with no luck. Thinking BCM? But there are more than one? My daughters car, in Florida, with summer and luv bugs, this is a must fix for the a/c.
