Where is the starter relay fuse on a 1997 Ford f150? ›

The starter relay is at the right rear of the engine compartment. You can check for any voltage drops with a multi meter to see if the relay is bad.

I found more info on this. Fuse #27 runs the fuel pump.

The blower relay is located in the blower/flasher relay block. It is under the dash, drivers side to the right and above the gas pedal.

Ok first check fuse no. 13 in the under dash fuse panel. If this fuse is ok you will have to get you at least a cheap 12V test light to find you problem. Now in the first schematic see the fuse on the left it provides power to the brake light switch on the brake pedal on the light green/red wire.

Failed Fuel Pump Relay

A small fuse from the fuse box controls this function. If you have trouble starting your vehicle and have these signs there might not be enough fuel drawn to the combustion chamber. Replace the fuel pump relay fuse or swap it with a different relay fuse and check if the engine turns this time.

A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.

Inconsistent or Intermittent Operation: The blower motor may operate inconsistently or intermittently when the relay is failing. You may notice that the airflow is not consistent, with the blower motor turning on and off unexpectedly or not functioning at all.

A/C Settings Won't Work. A bad control switch won't be able to accurately change your A/C system's settings. The button will most likely refuse to respond even if you try to increase the fan speed. In some cases, changing the temperature might even lead to the A/C turning off completely.

Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it. Start car and see if the blower motor works. If fuse blows again, check for loose circuits.

One of the best ways to determine if a car fuse has blown is by using a test light. It should illuminate both ends of the fuse, and, if it doesn't, it needs to be replaced. Sometimes, a blown fuse is caused by a damaged wire, motor, or other part.

Is there a fuse that controls brake lights? ›

Check Your Fuses

The first thing to check is whether or not the brake light fuse has blown. This fuse is usually located in the fuse box under the hood, and it's relatively easy to check. Just remove the fuse and hold it up to a light - if the wire inside is broken, then you'll need to replace the fuse.

Fuses protect the car's electrical system to prevent overloads. If your brake lights aren't working, a blown fuse could be the culprit. While fuses are inexpensive and relatively easy to replace, locating and accessing the correct one might be confusing. Each vehicle model is different.

In most cars, it will be under the hood, in a large box with a black lid. This is where car fuses and relays are installed. It is also called a fuse box. This box is usually installed on the driver's side of the vehicle.

If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won't turn over - no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.

You'll feel two relays to the LEFT side of the steering column. You want to remove the one CLOSEST to the steering column: that's the Starter Enable Relay. It just pulls straight out (toward FRONT of car). NOTE the orientation of the relay you've removed (where the spade plugs are, etc.).
