The fan speed resistor is most likely open.

SOURCE: blower moter has 1 speed

I would replace the resistor first. More than likely this is the problem and inexpensive.

Blower moter will run only on high


The most common cause is a bad blower motor resistor. It attaches to the blower motor and controls fan speeds. It's typical for a bad resistor to lose 1 speed at a time until you are left with just 1 speed as you are experiencing.

Blower moter quit on 2004 chevy impala


If the blower runs on the highest speed setting, a stepped resistor has failed that allows for the different speeds. If it won't run at all and the fuse for that circuit is OK, then either the blower motor, the switch, or a relay servicing it has failed.

FAN BLOWER (FOR A/C AND HEAT) ONLY BLOWS ON THE HIGHEST SETTING. IS THERE A FAN SPEED CONTROL OR RELAY THAT CAN BE REPLACED, OR IS IT SOMETHING ELSE?


Hello leebarker
The blower moter switch or the blower moter controler can cause this
problem. Remove the plug from the switch, use a 12v test light to locate
the 12v power wire in the plug. Next with a small jumper wire bring power from the 12v contact to the low and medium speed contacts on
the plug if the blower changes speed replace the switch if it still only
has high replace the controler. The blower controler is located on the
passenger side end of the heat-a/c box near the blower moter.
By the way the key must be in the on position for this test.
I hope this helps. Good luck.

Blower moter in my 2002 pontiac grand prix was workin on 5 only then quit all together.Replaced the blower resister today now only works on 5 and when on 1,2,3,4 automatic lights dont work.Any one know...


If the blower motor is bad ,this would happen ,the setting 5 gives it full voltage,but on the lower speeds lower voltage,and if the blower is bad,it will not run.

Replaced the climate control and blower wont work


f that just put power to the blower moter and see it it runs if you pull the relay jump a wire across the terminals with it out and add a ground wire to the case of the blower to another spot on the chasis if it still does not run your blower switch may be bad dont worry just run a toggle switch to a good blower moter
