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.
The Heater/Blower Relay is on the blower motor housing under the dash in the passenger compartment on 1999-2002 models
check the fuse, the relay, the switch and the blower motor resister. If these all check out could be the blower motor its self is faulty
check for voltage at the blower motor on all settings. if no voltage check the blower motor resistor or relay. if it has a resistor it will be right beside the blower motor, if it has a relay it will be the relay on the firewall under the hood.it will probably have a purple,orange,blue,and black wires.
replace heater relay and or heater 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.
There is a fuse for the blower motor on the fuse panel, I do not know of a relay.
It could be the blower motor, control switch, relay (if your vehicle uses one), loose connection or bad fuse.
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 relay on the heater/blower circuit on a Ford Escort MK6 is probably behind the glove compartment. There are two popular places that Ford puts its heater/blower relay switches. The other place would be next to the blower motor itself.
heater fan blower motor is burn up not working need to replace it could also be a heater relay typically located on the fuse panel that needs replacing could also be the switch on the switch panel
fuse or relay most likely
