1. Check the Fuses:
* Locate the fuse box: This is usually under the hood or in the passenger compartment (often under the dash). Consult your owner's manual for the exact location and a fuse diagram.
* Identify the blinker/hazard fuses: The diagram will show fuses specifically labeled for turn signals (left, right) and hazard lights. They may be grouped together or spread out.
* Inspect the fuses: Look for blown fuses – a broken filament inside the glass window is a clear indicator. Replace any blown fuses with fuses of the *same amperage*. Don't use a higher amperage fuse, as this is a fire hazard.
2. Check the Flasher Relay:
* Locate the flasher relay: Again, your owner's manual is crucial here. It's often under the dash or in the fuse box, but its location varies by model year. It's a small, square or rectangular component, possibly with a clicking sound when working.
* Test the flasher relay (if possible): Some relays can be tested with a multimeter, but it’s often easier to simply swap it with a known good one from another car (if you can find a compatible one). This is a simple and effective way to eliminate the relay as a possible culprit.
* Replacement: If testing suggests it’s faulty, replace the flasher relay.
3. Check the Bulbs:
* Inspect all turn signal and hazard bulbs: Make sure all bulbs are working and correctly seated. A burned-out bulb in *any* position can cause the entire system to malfunction, particularly on older vehicles. Replace any burnt-out bulbs.
4. Check the Multi-Function Switch (Turn Signal Stalk):
* This is a common point of failure: The multi-function switch, located on the steering column, controls the turn signals and wipers. Wear and tear, corrosion, or internal damage can disrupt its function.
* Testing is difficult: Testing this switch requires specialized tools or a good understanding of automotive electrical systems. It's often easier to simply replace the switch if you suspect this is the problem (it's relatively inexpensive compared to professional diagnostics).
5. Check the Wiring:
* Corrosion and broken wires: This is a likely culprit, especially with age and environmental exposure. Carefully inspect the wiring harness connected to the lights, the flasher relay, and the multi-function switch, looking for broken, corroded, or damaged wires. Clean any corrosion with a wire brush and electrical contact cleaner. Repair or replace damaged wires as needed.
* Ground connections: Poor ground connections can disrupt the electrical circuit. Check the ground connections related to the turn signal system.
6. Consult a Repair Manual or Mechanic:
If you're not comfortable working with automotive electrical systems, consulting a repair manual specific to your 1995 Ford Mustang or taking it to a qualified mechanic is recommended. They possess the tools and expertise to diagnose and fix more complex problems.
Important Safety Note: Disconnect the negative battery terminal before working on any electrical components.
By systematically checking these components, you stand a good chance of finding and fixing the problem with your blinkers and hazards. Remember safety first! If in doubt, seek professional help.
