Lindberg Dancin' 64 Impala Lowrider Blue Green Plastic Wired Rc Hoppin Car

This Hoppin' model with electric hydraulics works, but only partially. The down button lifts and lowers the drivers side no problem. However,  The up button does NOT operate the passenger side as it should. The button works, as you can hear the power trying to activate the motor, but something is stopping it from bouncing like it should. And sometimes the car gets stuck in the up position and you have to flip it upsidedown manually and push the button to get it unstuck. 😅 I know it sounds complicated, but there are only about 8 gears and a motor under the hood. It should be an easy obvious fix for someone who has even a little bit of mechanical inclination. But thats not me.
