2000 4x4 blazer ls

interior lights will not come on when any door is opened, will come on with dimmer put all the way up

dome overide when pressed multiple times (4 i think from my last 2000 blazer) will not shut off headlights but will turn off interiors when dimmer is all the way up. i think the person who owned it before me had an aftermarket alarm which is not hooked up anymore

in addition

ABS activates once when i first take the truck out and then never again on that trip unless it sits for a while

thanks for your input, i have a complete 2000 blazer working for a parts truck in my back yard. bought a new one because i smashed rear quarter panel on a telephone pole
