Alright, this is my first post but an important post. I have a 2004 trailblazer EXT which is pretty much loaded (which may be the first problem). My current issue is that over the holiday break (2009) the overhead DVD stopped working...now for the long part of the story.
SIMPLE...So I went into the fuse box (under the backseat) and replaced the 10amp fuse...pop, it blew right away. I disconnected the battery and replaced the fuse (this is the Onstar fuse which controls the DVD) and hooked the battery back up...pop, it blew right away. Took it to the service station, paid $100 for some guy to replace the fuse and it worked.....for 10 hours then it popped.
Took it back and they said the whole unit needed to be replaced ($1500) and that this "should fix the problem". Now I am not a betting man but I am thinking it is not the unit but possibly the wiring. I of course can tell this and the service guys are not willing to check the wiring as it could take a long time. BUT of course if the new unit doesn't work I would have to pay more for them to check the wiring.
I am looking for any input from any of you out there. I am not willing to look at headrest units etc but I am looking for a cheaper way to fix this thing, other than replacing the fuse every 10 hours. I am more than happy to start pulling the unit down and checking wires myself but I am not sure how to attempt this without busting the casing or a clip that holds the whole thing together.
Would love your feedback.
Thanking you in advance....Hobstar
