Where is the fuse for the air suspension on a 1997 Ford Expedition? ›

The fuse for the air suspension is #15 in the underhood power distribution box (see first illustration for location undder the hood). The compressor is located under the windshield washer reservoir.

To locate the fuse specification chart for your vehicle or to learn how to change a fuse, refer to the "Fuses" section of your Owner's Manual.

Resetting the air suspension on a Ford Expedition can be done by following a series of steps, including removing the appropriate fuse, setting the wheels off the ground, adjusting tire pressures, driving the car, unplugging the compressor, pushing off control valves, and plugging back in the compressor.

When air suspension fails, you'll know it. The most likely first symptoms are a lower, sagging ride height, or the selectable ride settings that no longer function. Other symptoms include a rougher, noisier ride, and sloppy handling through corners and over bumps.

An activated inertia switch keeps fuel from being pumped into the system to minimize the risk of fire in case the system has developed a leak. Once it is triggered, it must be reset manually by pushing a button on top of the device which restores current to the fuel pump.

Many cars did (and some still do) have a crash sensor that cuts off the fuel pump and those DO have a reset switch. Typically in the trunk area, sometimes marked with a sticker. Your owners manual will tell you exactly where it is and how to reset it. It's not difficult to do.

Several things, including a failed pump, a clogged filter, or a kinked or blocked fuel line, can cause this. If your car is not getting enough fuel, it may not be able to start, or it may run very poorly. Another common fuel pump problem is a failure to create pressure.

Generally the manufacturer's brand name and the actual part number should be enough to identify the right fuse. Unfortunately, this information is not always provided on the fuse, so this guide will help you to interpret the information that you might find on the fuse.

In most cases, the main fuse box is situated under the hood, near the battery, while secondary panels can be found in the passenger compartment, often hidden behind a removable panel.

Flexi Says: A fuse in a circuit diagram is typically represented by a rectangle or a squiggly line. The rectangle is more common in American diagrams, while the squiggly line is more common in European diagrams.

What are signs of a bad fuse relay? ›

A bad main relay can cause problems like a no-start condition, unreliable vehicle ignition, an engine that won't stay running, and an illuminated check engine light. Relays are electronically-controlled switches. They connect or break paths in a circuit to control electric currents and their respective devices.

Well, you see, that fuse protects the ECU (Engine control unit or ECM engine control module) from over amperage's. So if there's an electrical surge, the brain is protected. On a newer model car the ECU/ECM controls everything ignition related AT LEAST. Timing, ignition, air.

The air suspension system cannot function without the compressor. If the compressor does not come on at all, that may be a sign that it was overworked and has burned out or it could be as simple as a fuse or relay problem. Of course, referencing a proper wiring diagram is where the analysis should always begin.

The five suspension heights typically offered by ECAS are (from lowest to highest in terms of height) "Loading," "Highway," "Standard," "Off-Road," and "Off-Road Extended." Height is controlled automatically based on speed and undercarriage sensors, but a manual ride height switch allows control over the suspension by ...

The AC fuse on most HVAC systems is typically on the unit's control board. You'll normally find the board behind an access panel on the unit's lower compartment. While you sometimes have to unscrew areas to access the control board, others have clips.

Taking Longer To Air Up

This could be from an electrical issue, a failing or malfunctioning compressor, a clogged air line, or simply an air leak before the manifold. An air leak that affects the whole system will most likely occur between the compressor and the manifold.
