Mr. Michael J

The air conditioning went on my 2009 Enclave this summer and I decided not to have it fixed and continue to drive it until at least next spring. Now the engine cooling fan is running on high full time. My mechanic says that with zero pressure in the A/C system, the computer sends a signal to the fan to run all the time. Now I am faced with either a $2,000 bill to fix the A/C or buying a new car before winter. Can this be right?
