1994 Mercedes Benz 280 4 cyl Automatic

I have a 1994 Mercedes Benz and just recently the front power driver and passenger windows wont' go up or down. I dont know what to check. Don't want to take to the dealer.

Thanks so much,

Will the passenger window operate with its individual switch?

if they both failed at the same time then I would suspect a faulty convenience control module.
