replace heater relay and or heater blower motor
There is a fuse for the blower motor on the fuse panel, I do not know of a relay.
The 1998 Dodge Neon does not have a relay. It does have a blower motor resistor that could be bad.
Not sure about the relay, but there is a blower resistor assembly located on the heater case to the right of the blower motor.
In a 1997 Jeep Wrangler, the relay switch for the heater blower and motor is located behind the dash. It will be directly behind the HVAC knobs behind the dashboard.
The only relay in the heater system would be for the high speed function of the blower motor. That rely would be located under the hood, on the firewall, close to 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
Behind glove box in dash
it is next to the firewall near the heater coil
Go To Your Underhood Fuse/Relay Center Located Near The Master Cylinder. You Will Find The Relay There.
It is in an auxiliary relay box directly beneath the air filter hose. The blower motor relay is the large one second from the left as you look down from the right fender.
The high speed relay for the blower motor would be found under the hood, on the passenger side of the firewall, close to the blower motor speed resistor.
