"Works fine unless battery light comes on."
Anonymous, AL (2002 GMC Sierra 1500 Base Unsure)""Both brake lights continue to come on at random, but present no other issues than the warning lights. However, when battery light comes on it somehow crosses with the AC so that it does not function, and releases the cruise control. So far this does not seem permanent, and both recover and function well. Frequency is not predictable and may happen once a month or go several months without issues.""
