My 2000 chevy cavalier windshield wiper doesn‘t work,I replaced the fuse and it works when the engine is not running,but as soon as the engine starts,the windshield wont work anymore
you have a short in the system
sounds stupid but touch a bare wire to the wiper motor housing and the other end to a ground and see if it works. Chevy's have a thin ground on there wiper motors and if broken will do things like this. If its the problem just put a ground wire to the fire wall and it will last longer than a new motor. May not be the problem but is common.
