help.......... my onstar button and mic notworking on my h3t. is there a fuse for this mic?
or dealer service only ??

 

Did it work before? have you removed or installed anything near the dash light control module or the radio?

 

it has worked before, i did not install anything. The onstar and mic just stopped working

 

if you have an aftermarket radio and used a PAC adapter it might be faulty. you can try power cycling the truck. like remove the battery a few minutes then re attach .

 

thank you , i will do so, but i do want to ask , is there a fuse for the onstar , like ive read about online?
because i do not see one in the fusebox
ive seen some not so helpful articles mentioning the onstar module....
