CORRECTIVE ACTION
36. ONE REAR TURN SIGNAL DOES NOT WORK.
WARNING
Although KEY SWITCH must be on and battery ground cable connected to test electrical circuit
voltage, turn off KEY SWITCH and disconnect battery ground cable before doing resistance tests
or replacing parts. This will keep you from getting shocked and prevent damage to parts and
equipment.
NOTE
Scrape painted surfaces to bare metal before connecting test leads to ensure correct multimeter
readings.
Step 1 is for left rear turn signal and step 2 is for right rear turn signal.
Step 1.Test turn signal switch (1) as follows: Pull apart wire connectors (2 and 3).
Using multimeter set to ohms scale and adjust to 0 ohms. Connect red test lead to
wire terminal (4) and black test lead to wire terminal (5) on wire connector (3).
Push turn signal switch handle (6) to left turn position. Check for 0 ohms on
multimeter. Push turn signal switch handle (6) to off position. Disconnect test
leads.
If multimeter reads no continuity, replace turn signal switch (1) (page
2-664).
Step 2.Test turn signal switch (1) as follows: Pull apart wire connectors (2 and 3).
Using multimeter set to ohmns scale and adjust to 0 ohms. Connect red test lead
to wire terminal (4) and black test lead to wire terminal (7). Push turn signal
switch handle (6) to right turn position. Check for 0 ohms on multimeter. Push
turn signal switch handle (6) to off position. Disconnect test leads.
