Clear red. Was that done correct?Ground fault in wiring, shifter?Thanks for any help.
See if your ground form eninge to battery is any good first. Scan for codes, a pro model will need to do this it should be an orange/white wire from switch to pcm and black to ground at left side of dash. That could be loose. Check to see if pcm is getting a signal from switch

Is it not working at all or only when the head lights are on?
If so when the headlights are on, try turning the dimmer all the way down and see if it works then. If it is you may have a Central Timer Module (CTM) Problem, just fixed a similar problem on my 97 dakota
