check the fuse on the back of the headunit

haha i did..and it's not blown ...i put the old factory unit back in to check and it worked fine

 

[bradfordpoole 10+ year member]

Hmmm is there a fuse holder (little black box) in your constant 12v wire? If so check that one

 

[CMattox23 10+ year member]

i'll go check..i hope thats it but in the case that it is blown why is my factory unit working?

on the power wire of the eclipse not the car.

 

[bradfordpoole 10+ year member]

the fuse is on the yellow wire of your aftermarket HU harness

 

[CMattox23 10+ year member]

no fuse there sorry i misunderstood. theres a 15a fuse on the back of the hu that isn't blown. no ****ing power to it anymore though. i cannot figure it out

You probably have a short in the wire somewhere. When you touched the ground it may have melted the jacket somewhere and now there is an intermittent connection causing it to go in and out.

 

[CMattox23 10+ year member]

you don't think it would have anything to do with the internals of the hu itself?

 

[YoungBloodM50 10+ year member]

IDK. check everything else first. Then it must be the HU. Narrow it down by removing the possibilities.

you might have done it wrong

haha i probably ****ed two things up yesterday...hu's bein looked at tomorrow to see if it's fried...and i found out last night when it became dark out, my interior lights will not come on when the car's off or on, everytime i turn the car off my factory hu forgets my presets, the time, and the eq settings. my remote on my keys will not unlock or lock the doors, can't roll the windows down unless the engine is running, same with the locks............anybody has any input fill me in lol

check all your fuses in your fuse box

check all your fuses in your fuse box

Definitely this.

Also, again, check all your wiring. If there is a wire touching (causing it to ground out) then your constant wire might be jacked. Causing your presets not to work. But definitely check your fuses, I almost guarantee that there is 1 or 2 blown in there.
