We have a 1997 oldsmobile cutlas ciera. The heat is working but barely blows and sometimes doesn't blow at all. We think it's the blower motor and want to order the part but need to make sure this is the...


This could quite possibly be the issue but prior to purchasing a blower motor check the plug that runs to the blower motor for a burnt or frayed wire.usually when it works intermitenttently like this the wiring is an issue.If the speeds are not functioning correctly the blower resistor is having issues check the plug to the resistor as well.

Where is the blower motor located on a 1992 Cutlass Supreme S?


Blower fan motor is located under the passenger side dash.
Remove the panel and then unbolt everything in your way until you come to a sort of triangular shaped blower motor.

My heat in my cutlass supreme turns off when i switch the switch to high but works on low


Three possibilities. AND all you can do yourself!
1. Hi/Low Blower Relay. However these usually fail on low and works on High.
2. Blower Control Switch.
3. Blower Motor Resistor.
If you do not have one: buy a Voltmeter, available for $6 at Walmart.
If you do not have one: buy a Haynes or Chilton Manual at most auto parts stores for $20-$25 dollars. I say this because you are obviously going to keep this vehicle. It will have most of the information with pictures to assist you.
Quickest way to determine which one?
Finding the Resistor....Go on line to autozone.com or advanceauto.com. Answer the questions on year, make, model and engine and go to "look up parts" or click on "Replacement Parts".
Pull up the Hi/Low Blower Relay.
Know you know what you are looking for.
This Relay is located near the Blower Motor.
The System goes: Switches, Relay and/or Resistor, Motor.
Unplug the electrical connection from the Switches going to the Relay.
Turn the engine on. Turn the Selector to Low and using a voltmeter, check for voltage coming from the Switch. Turn to High and rechaeck for voltage coming fom the Switch. No voltage on High? The Switch is bad.
Do the same with the Relay to Resistor connection and or Relay/Resistor to Motor connection. Check the Low and the High voltages.
Let me know if this helped or if you have additional information or questions. Feel free to contact me at FixYa.com!

1971 Olds Cutlass Supreme. Dash brake light stays


They are unrelated. Just make sure your brake release is fully relesed. The switch turns the light on if the release isn't against it fully.

Fan on the air conditioning only works sometimes


Blower running all the time, even with the key out is a dead ringer symptom of a bad blower motor speed control. Replace that an your blower problems will disappear. See post below. For manual, call your local library and ask if they have online access to repair manuals.

Fan on the air conditioning only works sometimes


Sounds like the blower motor resistor which is under the dashboard on the passenger side near the blower motor. This is a small device that has three wires going to a plug inside the duct-work. You wil need a9/32 socket to remove the resistor.
