I saw this burned out connector and cannot find any info on it. The only thing I can find in the service is it is Connector C115 (I think). What do you think it is?

 

anyone?

 

I have a different vehicle, but based on the location it looks like it might be the Power Lead for the High Speed Blower relay on your HVAC. If so, it should come directly off the starter, through a fusible link, to the connector, and then to the high speed relay. At least on the G-bodies, they are very prone to melting like that. Poor connection in the connector, or too high a draw from the old blower motor.

 

Could it be a sign the blower motor is going out?

 

Old motors have brushes that are worn. A new blower is only about $20. A poor connection anywhere in the circuit can also add resistance, causing higher amperage draw. Usually it is a combination of poor connections and old motors.
