The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.
the blower motor relay is located next to the blower motor it is connected to the motor by a purple and black wires
On 03 silverados i belive the blower motor relay is internal to the blower motor resistor. i could be wrong though, check the underhood fuse/relay panel for one.
The blower motor relay only operates the high speed function. That relay would be in the fuse/relay center under the hood.
The blower motor relay for high speed would be located in the power distribution box under the hood.
Not knowing what year S10 you have, you can generally find the blower motor high speed relay nearby the blower motor on the firewall. The resister for the other lower speeds is also found close by the blower motor.
There is a fuse for the blower motor on the fuse panel, I do not know of a relay.
Where is the blower motor relay at.
Need to know what year. FYI, the relay for the blower motor only operates the high speed function. The lower speeds are operated by means of the blower motor speed resistor.
Its not the relay, it is the blower motor resistor.
check for voltage at the blower motor on all settings. if no voltage check the blower motor resistor or relay. if it has a resistor it will be right beside the blower motor, if it has a relay it will be the relay on the firewall under the hood.it will probably have a purple,orange,blue,and black wires.
The Heater/Blower Relay is on the blower motor housing under the dash in the passenger compartment on 1999-2002 models
