I have a 95 Dodge ram the overhead console is not working. The screen on the display is black will not even come on any one have any ideas were to start to fix the problem it came on a few times then would just lose power to it this is what I have done so far I have took the overhead console down and check the wires on or at the plug in I have checked the curcit board for any damage nothing was found look at the wires running down the piller the are connected

 

Not sure about dodge but on my Toyota and jeep (with a GM compass/mirror) it was some surface mount resistors. I will post pic's in a bit but, these resistors are little square things (maybe 1/8" by 1/8"). With some numbers on them. They get hot, cool, hot, etc then crack the solder joint and/or lift off of the circuit board. Take a magnifying glass and look at each of them. You will have to open up the unit. (I do not have one nor ever worked on one, so I cannot help you much on how to do that). When you find one that looks a little hinky, just touch with a hot soldering iron to re-seat it. Or just hit all of them.

 

Look at the item labeled "4R3" the left side of it. You can see how it looks hinky, that's a bad solder joint that needs to be fixed. On my Toyota, I actually removed the puny little resistor and put in some 1/4 watt ones, that take the heat better. You may want to check the inter-webs for a mod for that.
