Both the Automatic Headlamp System and the Daytime Running Lamps (DRL) are not working on my 2006 Tahoe. I can turn the Headlamps on manually. I have replaced the dash mounted Ambient Light Sensor. All bulbs and sockets look in new condition. I have checked the DRL Fuse and swapped the DRL...

My '99 Tahoe 5.7L is not starting easily for the last few weeks. It's not my daily driver. I replaced the Fuel Pump in June 2010 with a Bosch unit. Before installing that pump, the only way to start it was spray some starting fluid in the throttle body. That is not working this time. Now it...

My co-workers 2002 Tahoe has an issue with the exterior/interior lights. The Head lights, Interior lights and Tail lights will come back on after the Tahoe has been turned off. Tapping the brake will turn the lights off. Any ideas what to look for while trouble shooting? Thanks for the help.
