Question about 1992 Cadillac Eldorado
Had same thing happen on my 92 el dorado. problem is at the blower control power relay the 2 plug connectors or the connector for the blower fan. theree is a flow chart to test the voltages going to these connector in the factory shop manual, for a 92 el dorado on page 1C-17 if I remember correctly. if voltages check ok then make sure plugs are securely plugged in. if still does not work, then it's the blower control power relay. good luck!
