Using the multimeter, check for continuity through the

heater fan switch between terminals 27D and 399 with the switch in

the LO position, and terminals 27D and 400 with the switch in the HI

position.

If continuity is not present in both positions, replace

the heater fan switch, following the procedures contained in

paragraph 10-57 of the TM. However, if continuity is present, check

for continuity from lead 400 at the heater switch to lead 400D at the

heater motor. If continuity is present, replace the heater resistor,

following the procedures contained in paragraph 10-58 of the TM.

However, if continuity is not present, repair the body wiring

harness, following the procedures contained in paragraph 4-62 of the

TM. If the wiring harness is beyond repair, notify IDS maintenance.

Windshield Wiper/Washer System.

While reading through these

paragraphs, concerning troubleshooting of the windshield wiper/washer

system, refer to figure 7 on the following page.

Malfunction: WIPER MOTOR INOPERATIVE (GAGES OPERATE).

Step 1.

Inspect the mechanical linkage for evidence of binding or

Replace any linkage found to be defective, using the

procedures cited in paragraph 10-48.of the TM.

Step 2. Using the multimeter, check for continuity between lead 57F

at the wiper motor and ground. If continuity is not present, repair

the body wiring harness, following the procedures contained in

paragraph 4-62 of the TM.

If the wiring harness is beyond repair,

notify IDS maintenance.

Step 3.

Disconnect lead 27K from the wiper motor and, using the

multimeter, check for battery voltage at lead 27K with the rotary

switch in the RUN position.

If battery voltage is present, repair

the body wiring harness, following the procedures contained in

paragraph 4-62 of the TM. If the wiring harness cannot be repaired,

notify IDS maintenance.
