98 buick heater stop working


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.

1992 chevy suburban blower motor


If its not working at all try this.

Find it up under the passenger side of the dash. They are a real treat to get at. With the key on and the blower speed setting set to high tap on the blower motor. If it starts working replace it. If it doesn't start working let me know and I'll get you some info to check wiring.

All the heater blower speeds work on my 1998 Suburban except the high speed. I have replaced the blower motor and the switch. What else could the problem be? I have seen some writings about a resistor but...


Hello Boco.

In your Suburban there is a high blower relay.
When the switch to high is selected it activates a relay to another circuit that is fused separately.
This fuse in under the hood marked blower fuse 3 which is a 50 amp fuse.
This is most likely the problem.
However, if it isn't then the problem becomes the relay, the switch or a broken wire.
If it isn't the fuse, contact me back here using comments and I will help you with the next step in fixing your heater blower.

Thank you for using FixYa.
