Hi All, I have a 2005 Tahoe and am having an odd set of malfunctions. A. First off, when you use the left turn signal, the left, right and center rear lights all blink. B if you press the brake during a turn, they all go off. c. Sometimes the problem goes away. Have tried checking all the rear lights, connectors and plugs. Nothing appears wrong. The battery connectors look good with no corrosion (new battery) suggestions?
