Perform the foolowing to see if there are any trouble codes.
1. Turn ignition on. Set temperature control dial to maximum cooling, then slowly to maximum hot. After one minute, press AUTO and then OFF button. Simultaneously press AUTO and OFF buttons. See Fig. 2 .
2. If any problem exists in A/C-heater system when buttons are depressed, temperature indicator will light up a segment corresponding to the error code. The temperature indicator will then alternate every second between displaying "88" (all segments lit) and diagnostic trouble code segment. See Fig. 5 . If system is okay, segments will not light up.
Fault information is not retained in memory. In case of multiple problems, appropriate indicator lights will light up. If indicator lights "A", " C", "E", "I" and "L" light up at same time, common ground for sensors may be open.
