it's too late for a return. only got 30 days and i took too long to get it installed to determine it didn't help. just realized i didn't unhook the battery during removal / installation... don't know if that could have affected it...someone suggested a fuse or relay. looking in the owners manual , all i see abs related is a 10 amp fuse marked ac clutch, abs ingnition. the ac doesn't work , could this fuse being blown stop a scan tool from communicating with the ebcm ? also i seen ground wire as a possible culprit. anyone know where the ground is ?
