plinkers & seatbelt go on & off sporadically.

Yes, have not check fuse someone said I would have other things wrong if it was fuse and they would not work at all. I hear it make tbe blinker noise but can't see the arrows inside or outside.

Oh thank you SO MUCH for letting me know that. Mounted to the heater assembly under the dashboard, the body control module is responsible for transmitting the signals that are having issues. Don't check fuses, first time I have recommended that, and have the technician that did the diagnostics and repair to the heater find out what they did wrong during the job.

Thanks sooo much for you help. I will contact them.
