I was driving and my OD light started flashing, speedo, odometer and cruise control quit operating. I was in a major rain storm today, did something get wet? Truck is running fine. Thanks in advance, John

The ONLY way to know what's wrong is to read the code that's stored in the PCM.

Without the code all you can do is buy parts and install them until you get lucky and find the problem.

Whack your gauge cluster. Seriously. Same thing happens to my truck when it is humid out. I give the gauges a good whack, and they start to work. Oh, you've gotta be stopped when you do it too.
