It is located in the engine compartment, on the firewall, passenger side. Before pulling it, check for power to it. If no power, check for a corroded relay. It is located in a smaller relay box located right near the air filter box, between the engine and fender well. Kinda hard to see-. When you pull the cover, the relay will be in the #2 slot (2nd position from the radiator) the #1 slot is usually not used. It's only $7. Do not confuse this box with the power distribution/relay box on the drivers side.
Of course, first check the fuses.

First check fuse panel for burned fuse, if all o.k., Take a look up under passenger side dash, it's usually a common spot.When you find it, locate wires going into it & probe with 12vdc test light for power with key on & fan in run position. If light comes on by probing one of the wires, your fan motor is shot, if nothing at either wire, start back tracking for relay & switch malfunction.

It's less than foot from the heater core. I would guess that either the damper doors are not on correctly or the vent hoses are not hooked up. Can you hear the blower motor running? Maybe they didn't hook the motor back up when they replaced the heater core. It takes a ground and a hot wire.I can't remember where it's at but it may be part of the same unit. Did you check the fuse?
SOURCE: locating heater blower motor resistor
the resistor is behind your glove box. open the box and push in the sides to release it and let it hang down...the resistor is right there. I didn't try to replace it, a friend did it, but the part was under $20.
SOURCE: my ac/heater fan stopped blowing.
Does it work on all speeds, or has it only stopped on #1 speed for instance....the blower motor is located at the passenger side footwell...
