Top 10 2001 GMC Jimmy Questions & Answers

The flasher on this vehicle looks nothing like the flasher's of yesteryear. It will be located behind the drivers side knee bolster(under the steering wheel). It will be a small black box that is about 3 inches wide, 2 inches deep, and 1 inch thick. It may be somewhat difficult to locate because on some of the GM trucks they actually hide it behind the guage cluster bezel but to the left of the guages. Let me know if I can help you any further.
