GAdams You need to count the number of flashes. The number of flashes will give you the flash code or error code. IE: 3 flashes pause 3 flashes pause etc. = left motor short If you have your owners manual it should list the flash codes and what they mean for your chair. If not you can contact Pride Mobility @ 1-800-800-8586 and ask for Tech Support. If medicare paid for your chair the they will pay most of the repair cost. Contact the provider where you got your chair to see if they can repair it or refer you to a service Company that can. Hope this helps
