Hey guys, im having a problem with my 02 dakota. I lose power to my windows and windshield wipers, ive noticed that when the key in the ignition jiggles at all i lose all power, as of lately my speedometer has stopped working and abs lights are on. I changed the abs speed sensor on the rear diff and nothing. Then one day i go to move the truck up and noticed the abs lights are off in excitement i take the truck for a ride around the block no problems later that day go to get back in and bam! The abs lights are back on and no speedometer again. Ive summed this up to an electrical problem but dont know where to start, any advice?

 

There are multiple circuits on the ignition switch so it is very possible for some things to work and others not.

Sounds like it's time to replace it. It's not that difficult. The switch and lock cylinder can be replaced separately.
