92 olds cut sup s- keep going through batteries. On occassion cruise (nonfactory installed) won't work or will independantly speed up (as if resume), right blinker won't work unless I fiddle with wiring in back, left has failed only 1-2x, radio lights sometimes work, door will chime after 5-10min, (on highway) power windows and locks may cause the car to lose significant power, digital dash flickered on/off (new 5 yr ago), and engine will stall or almost when coming to a near stop. All these things have occurred spontaneously. At first,as I vaguely recall, my check engine light came on, diognostic said EGR but tested ok. After long frustration a safety switch,or something of the sort,was bypassed and it seemed ok, but since then these things have progressed. I won't even touch on the many repairs and replacements. ?????
