Well the car came to me with some 'no-name" 15 lb. solenoids, they worked ok untill I replaced the door weather strips. Then the 15 lb solenoids wouldn't release so I ordered some 35 lb. solenoids from "Rocky Hinge" company in Ohio. The new slolenoids worked great at first and the passenger door still releases with authority but the one on the driver side is lazy and weak. Seemed to go weak almost right away,( I put the new ones in about six months ago) but I haven't used the car much due to undergoing a complete refurbishing. Maybe I just got one bad solenoid?
