Turn Signal/Hazard Flasher

Turn Signal/Hazard Relay Input Test

22-126

Remove the turn signal/hazard relay (A) from the under-dash fuse/relay box (B).

Inspect the relay and fuse/relay box socket terminals to be sure they are all making good contact.

If the terminals are bent, loose, or corroded, repair them as necessary and recheck the system.
If the terminals look OK, go to step 3.

Make these input tests at the fuse/relay box.

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the turn signal/hazard relay must be faulty; replace it.

Cavity	Test condition	Test: Desired result	Possible cause if result is not obtained
1	Under all conditions	Check for continuity to ground: There should be continuity.	Poor ground (G501) An open in the wire
2	Ignition switch ON (II) and turn signal switch in Right or Left position	Connect No. 2 terminal to No. 3 terminal: Right or left turn signal lights should come on.	Poor ground (G201, G301, G501, G601) Faulty turn signal switch An open in the wire
2	Hazard warning switch ON	Connect No. 2 terminal to No. 3 terminal: Hazard warning lights should come on	Poor ground (G201, G301, G501, G601) Faulty hazard warning switch An open in the wire
3	Ignition switch ON (II)	Check for voltage to ground: There should be battery voltage.	Blown No. 19 (7.5 A) fuse in the under-dash fuse/relay box Faulty hazard warning switch An open in the wire
3	Hazard warning switch ON	Check for voltage to ground: There should be battery voltage.	Blown No. 5 (10 A) fuse in the under - hood fuse/relay box Faulty hazard warning switch An open in the wire
