Not sure about the 2000. I guess your Owners' Manual will say which fuses/relays it should be. For the 1996, check Fuse 37 and Relay 14 (for the heater blower) located in the Passenger compartment fuse box. Left and under the steering column next to your left knee. Push/pull knob/lever for the fuse panel to drop down.
In addition, check Relay 23 (in the steering column). I think this is also called the Flasher. Need to remove the turn signal Multi Function Switch to access it.
Here is a thread on the MFS.
