I have a 97 Town & Country, that won't stay running when I start it. The overhead console display is blank and gauges on the dash are inactive. Husbands friend scanned the system and came up w/ needing a new body computer..and said it's a $1000 fix. Does this sound right? what is the smartest way to deal with this... is the part findable in junkyard? Does it need to be 'flashed' once new part is installed? I'd be happy to hear any of anyone's experiences like this, thank you.
