Dash lights flickering and keeps blowing fuses affecting right side front and rear marker lights (tail light and front marker light right side only) replace the fuse and it may last a day or it may last a few months, I see lots of complaints about flickering and I think it's a short, the fan relay for the heater motor kept blowing and after replacing it twice and the blower motor once I found that the problem was in the connector harness (bad solder job at the connector) burnt so bad I'm surprised it didn't catch fire!! in motion and parked.
When driver or parked and idling the dash, indicator lights, headlights, tail lights, speedometer completely lose power. This has happened while driving in low light conditions causing a very serious hazard.
