Most likely the Blower Motor Resistor.
This is typically caused by a bad resistor. Could be the switch itself, but it's usually the resistor.
it is under the glove compartment on the passenger side of the truck
Its not the relay, it is the blower motor resistor.
If yourtalking about the heater blower, I believe they are hidden behind the glove box inner liner.
you have to remove the glovebox, its behind that, it has 2 bolts and a "connector", should be on the left side of the blower housing.
It is located on the passenger side below the dash. A 7-wire harness goes to it. It is next to the blower motor, which is circular in shape.
Yes, located in the blower motor resistor pack. Follow the wires backward from the blower motor to find it.
The blower resistor on a 1999 Chevy truck Z1500 is located behind the glove compartment. There is also a resistor on the firewall next to the blower motor itself.
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 heater blower for a 2002 Chevy Silverado is mounted under the dash. It is on the passenger side, in the heater housing.
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.
