Have an old, 1997 GM Opel, and now need probably new, scissors window device. What's the best way to find one? I'm in CM. Options seem the local GM dealer, some place in BK i don't know, import from EU via post, etc. Ideas welcome. Yes, could look into like new 2nd hand but even that is mysterious to me.

Don't think you would find any parts in country and if you did they would be very expensive. I would try the internet. Places like this one.

For S/H part try Meng Opel on facebook , Opel.in.th and on facebook also depending on the model a Deawoo part may fit.

or have a local repair shop do their magic
