I have recently had my roof motor pack in. Car sitting outside garage for 3 weeks maybe didn't help. I have with assistance from someone's step by step guide, removed my motor. It was wrapped in a cloth which was sodden. I have dried, cleaned and WD40'd the motor. It works on a 12v supply but after several seconds it starts to run rough. Perhaps because it isn't attached to the system. I am wondering if it is worth getting a new motor and relocating it. £80 sounds reasonable. I am in Falkirk and have a few roof issues. Working on them but if there is someone good, locally, that is great. Not yet sure if my motor is a goer, or if there is some other wiring issues leading to roof not working.
