Jakes not working right
 
The jakes seem to be weak and the high and low setting both work the same. The med setting does not work at all. When on they dont slow down the truck any. I think maybe it is something electrical? The truck is a 00 Western Star, Thanks :?:

your medium setting is not working. you need to verify if your ecm is seeing the input, the switch output might be live or ground depending on the make model year
