Relay Identification
« on: January 22, 2021, 12:12:54 PM »
putting my new dash in, and I have no idea where this relay mounts or how it mounts to the body/steering column/hvac box? It has long-ish wires coming off before it merges into the main harness behind the cluster, which leads me to believe it goes somewhere behind the radio/HVAC controls. Any ideas?

It is either the turn signal relay, or the seatbelt warning timer relay. If it looks like it mounts near the turn stalk, it's for the signals, and if it is the one that clips up near the ABS computer then it is the one for the seatbelt warning.

It's neither, the seatbelt timer I disconnected, and the turn signal is in place. Based on the wiring diagram its the HVAC controller, I just have no idea where it goes

Figured it out, it clips on the HVAC box, on the passenger side next to the recirc flap motor
