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!

My heater blowers dnt work and i need to knw where i can locate the resister blocks for my heater blowers so i can ghange them


Its located under dash,or near glove box.

The dash panel lower side has to be out.

HEATER BLOWER MOTOR


Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.


It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

The heater and air conditioner in my 1992 Daihatsu charade are not working. Can you assist please?


Do you mean the fan motor???? See if it will work on "high" speed only. If yes, replace the heater motor resistor. Otherwise you may have a bad heater motor.

The Blower Motor Resistor is located behind the glove box on the dash. Remove the whole glove box to access. The Resistor is mounted against/sort of into the fire wall.
1. Disconnect the negative side of battery.
2. Disconnected the Electrical Connection to the Resistor.
3. Remove the bolts/screws. I believe they have 8mm heads, there should be 2 of them.
4. Replace with new one/Replug electrical connection.
5. Reconnect the negative side last.
6. Test System before putting the glove box back in!
The Blower Motor is easy (compared to $1000) to remove and replace.
