Corp. Ref. No. 711209
Date Sept. '87
SUBJECT: NO LOW BLOWER OPERATION
MODELS AFFECTED: 1981-1987 REAR-WHEEL-DRIVE DE VILLE AND BROUGHAM 1980-1985 ELDORADO AND SEVILLE
Some 1981-1987 RWD De Villes and Broughams, and 1980-1985 Eldorados and Sevilles equipped with a non-BCM controlled ECC system may experience a condition of no low blower operation. This condition may be caused by a crossfeed on circuit 976. Confirm a no low blower condition by selecting the low setting on the ECC head and checking the voltage across the blower motor terminals. If this voltage is above 6 volts, the ECC system is not achieving low blower operation. Repair this condition using the following procedure:
1. Cut circuit 976 on both sides of the center bulkhead connector (C101).
2. Run a jumper wire through an open connector cavity.
3. Splice the harness wiring to this jumper on both sides of the bulkhead connector.
