I am in the middle of this Texas winter storm and we haven’t had power for 4 days. I needed heat so I went to sit in my car for a while. Well, I didn’t realize my windshield wipers were in the on position but a block of ice over the windshield was constricting them from moving. Now everything has melted, and although they still work, they stay running for at least ten seconds after I shut them off and they park in the wrong position. Also, the first three speed settings stay at the same speed. Is this a motor malfunction, or can I easily repair this? I know they can be recalibrated but I don’t know why they don’t shut off after I turn them off. This is the last thing I need on top of this disaster we have been dealing with this week. Any help is so appreciated. Thank you.
