I finished up a head cam swap and all is great except my asr ligjt is off and I cant turn it on or off if u let the car sit it will randomly work for a few and then shut off again has anyone had this problem and know what the cause is plus it seem to come on when u play wit the grounds on the drivers side head

 

Any idea on what it mite be would b great and it worked before the swap lol
