The trunk lid started giving us problems about a year ago . When it started to lift , it would get stuck and you would help lift it and then the motor/gear? would engage and the top would complete it's cycle. Now we're getting no lift at all .I can open the trunk and see all the mechanisms but I'm not sure what or where to check first . I'm an RV tech and handy with wrenches, meter , etc. I need some help troubleshooting this one . It's getting warm and we want to use the top .Please help me keep the wife happy. THANKS !!
