• Problem Abstract: Onstar and High Output Headlamps
  • Reported By: Stu Fleming (stufleming@home.com)
  • Year: 1999
  • Model: GTP
  • Applicable Options: Onstar, Hud, Moon Roof
  • Solution: replace components of On-star
  • Cost: Warranty
  • Other: I new GTP has the Onstar system installed in it. www.onstar.com for those who do not know what it is. i also installed high wattage headlamps and in the process blew the circuit for the On-Star System. It appears the Onstar is very tightly integrated into the cars "Nervous System" so adding even a minor load could cause an issue. please feel free to email with any questions. 4/23/1998 at 06:01:14 CST
