How to Relpace the Blower Fan in a 1998 Audi A4 Wagon


1. Open the passenger-side front door. Remove the plastic trim on the side of the dash that rests against the door. The trim is held on with clips and can be pulled off by hand.
2. Open the glove box door. Remove the five 8-mm bolts that fasten the glove box to the dash with a socket wrench. Disconnect the wiring harness for the glove box light. Remove the glove box, noting how the lower rear edge of it clips into place.
3. Locate the blower motor, which is a large, black, round part bolted to the underside of the dash. Disconnect the wires that go to the blower motor. The harness may be behind the motor and difficult to reach.
4. Remove the bolts that hold the blower motor to the dash with a socket wrench. Plug the wiring harness into the new blower motor to ensure that the new blower motor functions properly.
5. Install the new blower motor by bolting it into place in the reverse order that the old motor was removed.
6. Reinstall the glove box. Install the bolts and tighten them. Plug the wires back in to the glove box light. Reinstall the dash side trim.
