It's in the resistor block, which in the diagrams comes right after the fan control switch
The blower fan motor is worn out.
It is on the evaporator case and is held in with 2 screws.
Not grounded properly.
The 1998 Dodge Neon does not have a relay. It does have a blower motor resistor that could be bad.
If the blower works on some speeds and not on others, you may not need a motor. Instead, you may only need a new blower motor resistor.
99 TRNS PORT BLOWER RESISTOROn my 98 it is under the dash on the passenger side, you have to remove the glove box, and the blower motor it is behind the blower motor with 3 crew holding it in
blower motor resistor
Open the hood ...it should be on the left side of the firewall...right off of the blower motor box...
There is none - usually it is the module in the top of the heater / blower box (resistor module) that is the problem.
Hummm!! it Seems it is a known problem with Mercedes from 94 to 98. Is two problemsThe blower motor resistor can be defective andthe blower motor itself.
My guess would be the blower motor speed resistor is burned out.
Look under your glove box and locate the wiring coming out of of the blower motor. This wiring connects to more wiring coming out of the heater/ac ducting behind the glove box. That connecting wiring comes from the blower motor resistor. It is held in place by two screws, one on each side. Remove those screws and the resistor will slide out.
