the blower motor relay is located next to the blower motor it is connected to the motor by a purple and black wires
Its not the relay, it is the blower motor resistor.
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.
I think the blower motor relay is internal to the blower motor resistor which is located under the passenger side dash.
the relays are behind the glove box. you have to take the glove box out to have access to the relay for the heating system
The blower motor relay only operates the high speed function. That relay would be in the fuse/relay center under the hood.
When the blower motor stays on it means there is a short to power, or the relay is sticking. 99.9% of the time the relay sticks. I belive on the 2004 silverados the blower motor relay is internal to the blower motor resistor. Try to find an auxillary blower motor relay and if there isn't one then replace the blower motor resistor.
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.
The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.
There is a fuse for the blower motor on the fuse panel, I do not know of a relay.
Swap the relay with a known good one, many of the relays are of the same part number. Keep in mind that the blower motor relay only controls the high speed function. The blower motor speed resistor and the blower motor switch controls the lower speeds.
Where is the blower motor relay at.
