Hardtop Retraction Issue
Hello. I am having an issue with my hardtop 2009 Pontiac G6 GT with the 3.9L engine. I have never worked with hardtops in my career, so this is all new to me. But the issue I have is when I press the button to retract the hardtop, the motor can be heard(unless I am playing music), then you can hear the locks releasing. The trunk pops up slightly, about 2-4 centimeters or so, the motor shuts off, and the roof moves slowly leaving a gap, then the retraction slows and stops. nothing else happens if the button is held longer. I just bought this car from my work at another child dealership. If anyone can lead me in a direction to fix this, please don't hold back. Thank you.
P.S. I am new here.
