SERVICE INFORMATION

Some 1985-1987 Cimarrons may experience erratic A/C compressor operation. This condition may be caused by a corroded power steering pressure switch. To diagnose this condition, disconnect the power steering pressure switch and jumper across the connector terminals while the compressor is operating erratically. If the compressor stops cycling erratically, replace the power steering pressure switch, P/N 10041728. Should the compressor continue to cycle erratically, refer to Section 6E2, Chart C-101, for 1985-86 2.OL or Section 6E3, Chart C-10A, for 1985-87 2.8L.
