Hello everyone new here I just need a little help I have a 99 GC 4x4 and I'm getting a abs fault for pump motor circuit. I ran 12 volts to the motor and it does run . I opened the case and didn't see any bad solder joints so I'm in the market for a replacement unit. The module on my vehicle is 56041022AD B and the Mopar parts house gives me number (56041022AH) does anybody know if the two modules are interchangeable? Can I just get one out of a junkyard if the numbers aren't the same and will it work? Or do I need to find the exact same one ? It seems like they changed the unit on the 2000 model and up. Thank you to anybody who takes the time to read this.
