DESCRIPTION

If the air conditioner is operated after hot soak, the indicator light on the air conditioner switch may flash and the compressor will disengage, even though there is no problem with the air conditioner. However, the air conditioner will work properly if the air conditioner switch is reset. In order to correct this problem, a modified temperature control box has been established.

CHECKING PROCEDURE

To determine if the temperature control box or other component of the air conditioning system is the cause of the malfunction, use the following procedure.

1. Start the engine and turn the air conditioner on.
2. Check the sight glass on the receiver/dryer for the proper amount of freon. Refer to the 1983 Air Conditioning Technical and Troubleshooting Manual, (P/N 9999-95- 013M-83), page 18.
