I am just about to complete the purchase of a very well maintained 2010 Nitro SXT with only 75,000 miles from 1 owner. The vehicle looks like a new vehicle both inside and outside. The dealership has put a lot of time and work into issues. My main concern now is the A/C that was reported to need a new compressor from the previous owner's service center. My dealership tells me that they cannot find a problem with the A/C and cannot confirm the need to replace the compressor. The A/C blows only cool air on any day. How should I handle this with my dealership?
