Hey folks-
I recently purchased this 2012 Explorer at auction. At the time of inspection the SYNC touchscreen worked, but after bidding, when I went to go pick it up the screen was out.
I took it in to the dealership, and was told that the module needed to be replaced and I was quoted at ~$1,100. I told them to order the part and give me a call the next week when it was supposed to come in.
During that week, while we waited. The screen came back on and worked for 2 weeks straight with no issues or concerns. So I called the dealership and told them to keep their module. Now, it's gone black again and the family car is without audio or heated seat controls.
This time I decided to investigate it before taking it back in and coughing up $1,100. I have tried restarting using power and >> to no avail. I have pulled the 29 fuse a couple times and each time the audio kicks on for about 30 seconds before cutting out but I don't get so much as a flicker from the screen.
From what I've read, there's no promise that replacing the module would even fix this issue, and aside from disconnecting the negative from the battery, pulling the 29 fuse, and using the Sirius voice control USB trick all to force a restart, there don't seem to be any definitive ways to address this issue.
Is there anything else left to try? Does the 30 seconds of audio indicate anything?
Thanks!
