Ford Fiesta — High speed running of blower fan after switching on a/c and does not come back to slow speed.

I had given my car to cargo Ford, Baroda on February 13/ 2014 with the problem of excessive noise due to running of blower fan at high speed immediately on switching on A/C . This was attended by Cargo Ford, Baroda, and I was charged Rs. 5000/- for attending the problem. It seemed to have been solved but after two weeks the high speed issue restarted. Cargo Ford was informed about it in the month of March 2014.The problem was again discussed with the service technician named Mr. Bhavsar when the car was given for servicing on 12/4/2014. However it was not attended to and the problem remained. Third time the car was taken to Cargo in the second week of May (This visit to Cargo ford was not entered in the records) I was told the noise of blower fan was due to its running at high speed as it was summer time and the ambient temperature was very high though it was explained that the blower ran at high speed immediately after switching on the A/C even in the early morning when the car was started for the first time at 5 AM. It is also brought out that the temperature on the dash board during day time showed 60 to 70 degrees and never above 70 degrees While the problem was being faced. Also the problem had started the first time when the ambient temperature was 12 degrees c at Udaipur. The car is around four and half years old, is single hand driven and has run around 35000 km. I have again given the car today (21/05/2014) to cargo Ford . I AM GETTING SICK OF FORD CAR, I WILL NEVER EVER BUY A FORD. (Email...[protected]@hotmail.com)
