Does a 1992 dodge ram 350 van have relay for the blower motor?
Yes, a 1992 Dodge Ram 350 van almost certainly has a relay for the blower motor. While the exact location and specifics might vary slightly depending on options and trim level, blower motors in vehicles of that era rarely run directly off the switch due to the high current draw. A relay is used to switch the higher current circuit. You'll need to consult a wiring diagram specific to your van's year and model to pinpoint its location in the fuse box or underhood relay center.
