The dash light will not illuminate when I press the "on" switch for the cruise. It did illuminate once last night while driving, but still wouldn't set. After shutting down and parking at the restaurant, again, it didn't light up when pressed. Is this the switch going bad/needing replaced?

 

Problem solved. Found out this was related to the same problem I was having with my tranny shift problem. Did the ECM plug cleaning trick suggested in my other thread about no overdrive, and fixed all problems!!!!!!! Not bad for 2 minutes of work and a little WD40.
