$1400 seems kind of steep..... BUT, i've never replaced a compressor on one so im not sure where its located. Hell, I've replaced alternators that were $400-$500 in labor alone because they required dropping the entire subframe of the vehicle. Wonder if its a case like that where they burried the compressor in the bottom rear of the engine and thereby requires a lot of R&R labor?

Ask the tech for a breakdown so we have a better idea of what they're charging.
