I'm new to the forum, have an '09 Commander with a 4.7. It has the Boston Acoustic system with the DVD player in the dash (I think that is a useless feature by the way - the DVD in the dash). I'm having random problems with the dash cutting out. The gages dip to zero, and the radio cuts out. When I bought the vehicle, it was doing that, and the dealer fixed it. Then my front diff went out, and ever since, it's back (I hope nobody ever has to find a reman diff out there). Car has 130,000+ miles on it.
Here's what we know. I've invested two hours of labor by a good mechanic in checking the entire charging system and fuse panel. Everything is okay there. The Park Assist switch is always off, and I cannot turn it on. It was working when the system wasn't doing this. Every so often the fan won't start up on the A/C - heat. It eventually cuts on. It's as if there's a wire loose somewhere, but I've been told that if the Park Assist module is bad, I should start there. I have been through the car wash at times, and when the air is whirling around to blow off the water, there have been times when the dash is looking more like a Christmas tree.
Where do I start? I've been told the park assist module is pretty expensive. Thanks in advance for any help.
