Blower Motor

I have a 1995 plymouth neon, my blower motor quit yesterday. Fuses were good, I unplugged the connection from the motor and put it on the battery and the motor worked. I plugged it back in and grounded the negative wire from the motor to a screw on the dash and the motor worked but only full speed. On the climate control it seems that the temp selector works and the switch from heat to ac to vent ect. works, all except the fan speed control. Do you think the speed control is bad or did I loose ground somewhere else. If it's somewhere else, where can I look?
Thanks,
Joe

 

Sounds like maybe the resistor crapped; its what controls fan speeds. Not sure where it is mounted on a Neon, but the one on my wrecker is mounted right in the ac plenum (to cool it since resistors create heat).

 

i think neon is on the hvac case on outside under hood

but yes it sounds like the resistor

 

What does the blower motor resistor look like? I'll take it off and buy another one.

 

here is the replacement procedure sounds like it is under the right side cowl screen

Remove windshield wipers.
Remove cowl top screen.
Disconnect the resistor block wiring connector.
Remove two resistor block retaining screws. The screw threads attaching the resistor block are not full length. It is necessary to gently pry out the resistor block while turning the screws counterclockwise enabling the threads to engages.
Remove resistor block from vehicle

 

Thank you Brian, I'll give it a try today.

 

Hello, I did replace the resistor block. The old one didn't look bad. It still isn't working. I left the new one in. The only way I can get the blower to work is to physically ground the black wire that goes to the blower motor. The motor is only on High speed at this point. The speed control has no affect on it, however the temp. control and "vent, heat, ac,"ect all seems to work.
Can you suggest any other place I can look for a problem with it?
Thanks,
Joe

 

hmmm how does the black grounding wire look sense that seams to be causing trouble. maybe replace that. im assuming its black as you say thats the wire your grounding.

 

Know what, it does "look" ok but I didn't check it. I'm going to run a new ground and see what happens.
