If your car won’t start, a fuse keeps blowing, or you’ve already spent money at a shop with no answers, you’re not alone. At Caleb’s Car Care, Mobile Diagnostics and Repair in San Antonio, we specialize in figuring out what others miss.
Whether it’s an electrical gremlin, a drivability issue, or a mystery noise, our Ready-Set-Go™ Method finds the real cause—not just guesswork or parts-swapping. You choose the level of inspection that fits your needs.
FAQs
-
Your visit includes a system scan, relevant testing, visual inspection, and real-time explanation of findings. We bring the shop to you—so we can test components under actual operating conditions. We’ll provide a summary of what we found, what caused it, and your repair options. Most mobile diagnostics last 45-90 minutes depending on the issue.
-
No. If we recommend a fix and it doesn’t solve the problem, we refund your diagnostic fee. We don’t charge for wrong guesses.
-
Intermittent concerns can be very difficult to diagnose and sometimes can require multiple hours of diagnosis to come to a concise conclusion. Using a wide array of service data tools our technicians are equipped with as much information as can be expected by an independent repair facility to correctly, diagnose concerns quickly and effectively, even when they don't show their face consistently.
-
Absolutely. We don’t just read the code—we dig into the system, sensor signals, and conditions that triggered it.
-

Our Diagnostic Philosophy
At Caleb’s Car Care, we don’t just scan for codes—we solve problems. Modern vehicles can throw multiple codes for one issue or a single code for unrelated problems. That’s why we rely on training, real-world testing, and factory-grade tools instead of shortcuts.
Our goal is simple:
Find the real cause of your concern
Explain it in plain English
Help you decide your next move with confidence
We’re here to out-diagnose the dealership—without the dealership games.
Common Issues We Diagnose
Car won’t start or hard starting
Repeated blown fuses or battery drain
Check engine light or warning indicators
Rough idle, poor fuel economy, or stalling
Strange smells, noises, or vibrations
Faulty sensor readings or inaccurate dash info
If your concern points to an electrical fault, we can go deeper with our Electrical Diagnostics service.
Tools and Methods We Use
We combine OEM-level tools with proven testing methods to deliver accurate results every time.
Professional-grade scan tools with OEM access when needed
Multimeters, test lights, and pressure gauges
Live data monitoring and freeze-frame analysis
Factory service manuals and technical bulletins
Visual inspection and functional testing
VIN-specific wiring diagrams and flowcharts
Once we identify the problem, we explain what’s wrong and your options. If it can be fixed on-site, we’ll handle it immediately. If a part needs to be ordered, we’ll give you an exact quote—no pressure, no surprises.
Why You Shouldn’t Wait
Ignoring a car problem usually makes it worse—and more expensive. A small short can turn into melted wiring. A misfire can destroy a catalytic converter. The sooner you get a diagnosis, the more likely it is to prevent bigger repairs down the road.
