so i have a 2000 chev blazer..
gauges,cd player, wont work untill headlights are turned on...and when you move the dimmer up or down the dash just flickers and then goes back to same brightness.. I installed new dash switch. and have notices on the harness the blue wire has been tagged and leads to a remote start.

Body Controll module?
Bad Wiring to remote start?
im more flustered then puzzled.....

 

i also have removed the remote start, and the theft bypass module.

Im starting to think i may have to take the entire dash out and fix any old haggled wiring to and for the remote start

other problems ive had are with the speed sensor..i replaced the pigtail for the speed sensor...and also the speed sensor but it wont shift auto when in drive but will go to second if i shift from 1-2 but no 2-3 it just acts as it is in neutral.
