Ok so i went to start my car today for a cruise downtown... as i heard the antenna come up i heard thump thump thump thump as it reached the top so i was like ok what the ****... so i shut it off and turned it back on so the antenna would come back up it went up half way... then again off on, came up quarter's way up... then when i shut it off it stays about a third up... is my motor going? Is there something blocking it? I never had this problem before... could weather be a factor it was 30 out when i did it. Any help would be cool...
