The blower motor relay (Voltage Reduction Relay or VRR) is mounted with a single screw directly to the instrument panel's structural plastic inside the glove box opening, next to the left-side energy-absorbing bracket (Fig. 20).

(1) Disconnect and isolate the battery negative cable.

(2) Roll down the glove box as described in the Glove Box section of Instrument Panel Systems.

(3) Using a short or 90 degree screwdriver, remove the screw that secures the blower motor relay (VRR) to the steel clip in the instrument panel plastic flange.

(4) Maneuver the VRR into the glove box opening far enough for access, and disengage the wiring harness from the relay.

(5) Remove the relay through the glove box opening.

INSTALLATION

(1) Position the relay into the instrument panel inside the glove box opening.

(2) Align the VRR with the connector and engage the wiring harness to the relay.
