2010 GMC Terrain: Saga Of The Dead Signal Lamp
January 06, 2011
Noticed last night on my way home that the Terrain's right turn signal was out. When activated it exhibited the classic "fast blink" symptom I remember from my bulb-slaying high school ride. The video tells the story and reveals the culprit. Left turn signal shown first as standard.
And because conventional screws are apparently banned on modern cars, the culprit taillight is held in place by two 10mm bolts hiding under under cosmetic covers, which in turn hide under the rear hatch. Good theft prevention, I suppose. Removal is still fairly simple. Two bulbs cost $5.49 at Pep Boys. The whole process took five minutes and the blinking is now back to its normal pace.
