I think the blower motor relay is internal to the blower motor resistor which is located under the passenger side dash.
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 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.
You can find the 2004 Nissan Maxima blower motor relay switch beneath the passenger side dashboard. The blower motor relay switch will be behind the glove compartment.
Bad blower resistor?
its located behind the glove box on top of the blower housing.
Go To Your Underhood Fuse/Relay Center Located Near The Master Cylinder. You Will Find The Relay There.
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.
It's under the passenger side of the dash.
Should be at the passenger's side firewall
check fuse / relay if both are good you may need a blower motor
On a 2004 Chevrolet Silverado in regards to a relay for the torque converter. After very intense research I cannot find anything that says it has a relay. I have never heard of any vehicle having a torque converter relay.
