This was my first repair on a turbocor compressor. The IGV on compressor #1 stop responding.......couple months later compressor #2 IGV stop responding and got stuck in a fixed position just like #1 compressor. We talked to DTC they said there was a problem with some of the IGVs installed on some of the ealier compressors. Just finished up the repair today...... compressors came online and loaded up correctly.
