Honda Civic power windows may stop opening or closing due to defective window switches. The issue may be intermittent with no obvious reason as to why the issue started or resolved itself. Sometimes if you press or pull the switch with a little more force than normal it may operate. All these are signs the electric window switch may be failing. While it's most commonly the switch make sure you or the mechanic at the shop verify the switch is bad and not the window motor before replacing any parts.
