On 5/31/2010, I had the rear Blend Door Motor replaced, due to, it was making a clicking noise . Malcolm - Cunningham charged me $623.97 parts and labor for this service . It did fix the problem at that time . On around 11/15/2010, I started to hear the same clicking sound, I had heard before . I called Malcolm - Cunningham, at that time, and was told to bring back my Explorer, and they would look at it . Unfortunatly, I was not able to bring my vehicle in until today, 01/17/2011 . They looked at my Explorer, and, told me that it was the same problem that I had had before . The Rear Blend Door Motor is the problem . The service Adviser told me that I had driven over 13, 000 miles since it was first repaired, and that, it was no longer under warrenty . He told me he would give me a discount on parts and labor . He said they could fix it for, around, $450.00 . I declined . I think that the work that I had done originally, was not of good quality . The original Blend Door Motor, lasted for 8 years, and, the replacement motor lasted for 7 months . Something is not right with this . I have been a loyal Ford customer for the last 20 years . But, if this is the way I am to be treated, when I have work done on my vehicle . I am going to have to look at going to G M, or to some import vehicle . I had been happy before, but, this really stinks . Orig . inv. # C90891 5/31/2010 New inv. # C03237 01/17/2011
