just bought another 2001 ranger today. noticed the cruise control didn't want to work. pressed the ON button, then pressed SET and my SPEED CONTROL light blinked once. the cruise control did not engage. I ran the KOEO test, and all the switches on my steering column blinked once like it said it should. I am not sure where to go from here.
I tried the test in my old ranger that I am replacing, thanks to being rear-ended on the freeway and totaling it, and it worked on that one. I remembered seeing something about that switch while browsing online, and decided to swap them out. Worked great.
