Want this question answered?
the blower motor relay is located next to the blower motor it is connected to the motor by a purple and black wires
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.
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.
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.
The Heater/Blower Relay is on the blower motor housing under the dash in the passenger compartment on 1999-2002 models
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.
