Chassis and Brake Warning Lights On After E-Brake Repair

What the customer reported

The customer previously had repairs performed on the e-brake component. Following those repairs, the chassis warning light was illuminated and the brake warning light was also on.

What we found and did

The technician traced the warning light concern to the ABS Wheel Speed Sensor on the driver rear, which was the starting point for the main concern. The technician removed and replaced components as required to access and install the sensor, then retested and verified the repair as required. A final road test was performed where applicable. The visit also included further diagnosis billed at $99.99 per hour.

What the customer reported

The vehicle was towed in because it wouldn't start after installing an aftermarket alarm.

What we found and did

Pro tip

Aftermarket alarms can sometimes interfere with your car's electrical system. If you experience starting issues, consider having the alarm professionally removed to prevent further complications.

Front Windows, Headlight Switch and Stereo All Quit at Once

What the customer reported

The vehicle owner reported that multiple electrical issues all began around the same time about a month earlier. The air conditioning first blew warm air and then stopped blowing air completely, the front windows did not work while the rear windows still did, the stereo had no display lighting and did not work, and the headlight switch, high beams and turn signals were not functioning.

What we found and did

The technician performed an electrical diagnosis at our Haines City shop, covering initial testing and inspection of the system, to address the vehicle owner's list of concerns. The technician's notes do not list a specific fault found. The shop's recommendations included a multi function, turn signal, cruise control and wiper switch assembly and a used radio, but none of that work was performed on this visit.

Truck Attempts to Start Without Key

What the customer reported

The vehicle owner reported that their truck was trying to start on its own without a key in the ignition, and the negative battery terminal had burned off and was found on the floorboard.

What we found and did

The technician performed an initial assessment and determined that the ignition switch needed to be removed and replaced. This was executed to address the issue of the truck attempting to start autonomously.

Result

After replacing the ignition switch, the truck no longer attempted to start on its own, resolving the issue.

Pro tip

If your vehicle starts cranking without a key, it could indicate an ignition switch problem. Addressing it quickly can prevent further electrical damage and costly repairs.

FAQ

Electrical Repair in Haines City: questions answered

Answered by our technicians serving Haines City.

Why does electrical diagnosis take longer than other repairs?

Because the fault is almost never where the symptom is. Tracing a circuit means following the diagram from power through the switch, the module, the load, and the ground, testing at each point until the break shows itself. It is slower than swapping a part, and it is the only way to be right the first time.

Can you find a drain that only happens some nights?

Yes, though intermittent drains take longer than steady ones. Sometimes we need the vehicle overnight so we can watch the current draw over time and catch the module that is waking up. We will tell you up front if your symptom is the kind that needs to sit with us.

Can I just keep jump starting it until it gets worse?

You can, but every deep discharge takes life out of the battery, so you often end up buying a battery on top of the original problem. The drain is also still there and can leave you stuck somewhere inconvenient. It is cheaper to find the cause than to keep paying for the symptom.

Do you work on aftermarket stereos, alarms, and remote starters?

We can diagnose problems they cause, and add-on equipment is a common source of drains and strange faults because it gets spliced into circuits it was never meant to touch. We will trace what it is doing and show you what we find. If the right fix belongs with the installer, we will tell you that too.

How do I know I will not be paying to have parts guessed at?

We tell you what we are going to test and what that takes before we start, then come back with what we actually found and what it takes to fix it. Nothing beyond that happens without your okay. Brian and Niki built this shop on putting the customer over the money, and diagnosing before selling is what that looks like in practice.
