I ordered this part for my parents when their compressor went out on their vehicle, then they discovered that theirs was not broken but that it was an electrical issue with their vehicle. This was purchased in August 2012 and has been sitting in my garage ever since. Purchased from A-1 Parts Depot in Orange, NJ as a tested, reconditioned and fully functional unit. Guaranteed. Since we don't need it I am selling it for half what I paid, to get it out of the garage and into the hands of someone who needs it. Feel free to ask questions if you have any.
