This part also malfunctioned on my VX last year and needed to be replaced. I went online and found a Newer Replacement than my 2001 at a Salvage Yard on Long Island. I discovered that the Isuzu OEM part is Exactly the SAME for I think the Trooper or Rodeo maybe Both! Merlin could explain. Took a Few Minutes to Install by my Mechanic and it works like a Charm ever since !
