I was having trouble with my wipers, radio, heater, and windows. So after checking all the fuses we pulled the steering wheel cover off and was looking for anything out of place. There was nothing in that since so I seen there was a black box under the shifter so I tapped it a couple times and everything started to work. So I know I have to change that just really not sure what it is? I know it has something to do with the ignition?
