I don't know if it is that.... there isnt really a "service 4wd light" per se. I haven't paid attention to the group for a while (sadly) since my '95 has been trouble-free. This blinking light is in the switch panel on the dashboard. I am used to the shifter on the floor. Is there a message that says "service 4wd" that comes up? Adam
