If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mec hanics and all. Plus i know a website that sells very cheap but very very good manuals online, without expiry i.e. for lifetime.
for this u can try reliable-store which is pretty good

this will need inspecting by a auto electrician as it would seem either the motor that lowers the roof is either faulty or there is a problem that is earthing out the component somewhere, worn wire or something like that, these are nearlry impossible faults to trace without the correct tools and knowledge
