Check out my video DIY tutorial for changing a burnt out map light bulb in a 2000, 2001, 2002, 2003, 2004, 2005 & 2006 GM Chevrolet Tahoe.
These DIY instructions should be the same for other similar General Motors vehicles such as the Silverado, Suburban, Avalanche, GMC Yukon Denali, Sierra, Hummer H2 and Cadillac Escalade.
