good afternoon my name is ***** ***** I will assist

yes, you need another converter. unfortunately, a lot of aftermarket converters do not meet OEM standards and will fail in about a year. we use only walker units or the factory units which are more expensive but last and have a warranty against the light coming back on.

was it a napa converter or another brand???

ok, the first thing I would do is call and see what there warranty is for the part. NAPA does say 1 year on there parts. if they do and will warranty it, I would ask for an upgrade to a walker converter to eliminate the possibility of having the same issue a year from now.
