Yes, there is a high speed relay and it should be in the fuse/relay center under the hood.
The front blower resistor on a 98 Dodge Caravan is replaced by removing the cover and disconnecting the wiring harness. The resistor can then be pulled and a new one put in its place.
The wiring harness on a blower motor for a Ford F150 is connected to the blower itself and the resistor switch that is under and/or behind the glove compartment on the vehicle. This resistor switch is a set of 3 or 4 wires connected by a plastic clip.

Pull out the lock on the blower motor resistor wire harness connector to unlock the connector latch . Depress the latch on the blower motor resistor wire harness connector and disconnect the connector from the resistor. Remove the two screws that secure the blower motor resistor block to the HVAC housing. Remove the resistor block from the HVAC housing............
The a/c heater blower motor resister is located in the vehicle on the passengers side inside the housing next to the blower motor...............Remove the blower motor resistor wire harness connector.Remove the blower motor resistor screws.Remove the blower motor resistor.
The blower motor resistor is above the passenger side close-out panel, below the glove compartment and towards the firewall. There will be a wiring harness leading from it to the blower motor and another harness leading into it. The harness leading into it will have a 4-wire connector and the harness leading to the blower motor will have a 2-wire connector.
It should be called the auto HVAC blower motor resistor wire harness. Goes from the auto climate blower motor resistor to the blower motor.
the resistor is gonna be right off the blower motor attached to the blower motor by a wire harness should be by the heater core
Under the hood. In the blower motor harness connector.
YesYes
A blower resistor can be replaced, in your 2002 Oldsmobile, by removing the resistor wiring. Remove the retaining screws. Reverse the process to install the new resistor.
With great difficulty!
