Stevens Ford

took my 2010 F 150 in because the lights would come on and off every five minutes, the air conditioner was not blowing cold, sometimes the starter would stay engaged. I made an appointment, delivered my vehicle the evening before my appointment. They had my vehicle for two days , did not do anything to it but set it out side in the lot. When i called to check on it the service adviser told me they would check to see if the technician had started the work on it and call me back, never called. When i called back they told me the tech. hadn't been able to duplicate anything the truck was doing, so I could come and pick up my truck. Air conditioner was blowing 85 degree air. They did not charge the air conditioner or me. This is the second time this has happened, last time they had my vehicle 3 days and did nothing. I will not go back, and I will not buy another Ford product.
