Mystery Electric Problem - Unbelievable
2006 commander 4.7L. Had auto starter installed December 2014 - worked fine. Moved overseas for military in January and car arrived in March 2015. Since then have had flashing dash lights and headlights (when in "off" and "auto" position), blinkers, wipers, back up sensors work sporadically (as if power is off and on repeatedly), tach and speedo jumping in sync - zero, then read accurately, then back to zero - error msgs like "service suspension" also appearing randomly. Problem got worse - in early April radio worked, but now, no power to radio. Talked to auto starter guys who recommended reset of control module (possibly got screwed up b/c of battery disconnection during shipment), but that hasn't helped. Can hear clicking under dash when key is in acc and on position. Clicking associated with lights (and everything else) going on and off. A.S. guys say that the clicking is the module trying to start car but it still happens when I disconnect module!
Based on write ups here, have replaced ignition switch, battery, multi function switch to no avail. Clicking coming from behind the two large circuit breaker looking things under steering wheel on left side. Am at wits end. Wondering if you guys have any ideas. Am in a place where I am loathe to take it to a local mechanic.
Sure do appreciate it. Thanks.
