heater temperature valve actuator GM part# 16124952[blend door motor]
 

1995 convertable standard, the connection from the motor on the one i removed is different from the ones with this part # although the connector slides out of the motor it will not fit into the new one pls help i have pics of both

The one on right has a shoulder around the base of the white plastic shaft extending from the main body of the housing. It is this shoulder which keeps the assembly from sliding all the way into the ac/heater box. All after market replacements that I have found have this same incompatibility even though they claim to fit...they do NOT. Genuine gm part number 16124952 is the only one, in my experience, that will fit.
