The tale so far - e-mail sent to service manager:
Xxxxx,
My wife brought our 2007 entourage in for AC service on 7/8/09 and told the service person that the air conditioning was "not cold" ref: service ticket XXXxXXXX
The service ticket states: "low on freon - charge and evac a.c. system"
I did extensive investigation on the cause of sudden loss of cold air and was told to check fuses under the hood. The night before her appointment, I did check and found the 7.5 amp compressor fuse was blown. I have been informed that the most likely cause of this failure is with the compressor clutch field coil having insufficient resistance. (TSB 07-97-003). I saw no note of a resistance check being performed or of the fuse being replaced.
I checked after the service and found that the 7.5 amp fuse has been replaced with a 10 amp fuse. I am not an auto mechanic nor an electrical engineer, but I know that it is not a good practice to fix an electrical problem with a larger fuse. My concern is that the service did not fix the problem, only masked it and may indeed have exacerbated the problem.
I am extremely concerned that this could lead to further problems which could cost us a fairly large sum of money after the warantee expires.
I would appreciate hearing from you regarding this matter. I can be reached during the day at XXX-XXXX or in the evening at XXX-XXXX.
Thanks in advance, XXX
