I installed my amp steps over a year ago id say. They have worked awesome so far but the drivers side is giving me issues. When the weather is warm the step retracts and extends fine......as soon as it gets cold (say around mid 30s or colder) it dosent come all the way down or fold up tight. Ive checked the wiring and all the connections are good. The next thing Im going to check is if it binds with the motor taken out and its cold. Any other ideas or what to check?
