Comprehensive Auto Electrical Repair & Maintenance Services
Our team handles every part of your car’s electrical system with real attention to detail. We get things diagnosed and fixed fast so you’re not stuck waiting around.
Alternator
The alternator keeps your battery charged and converts electrical energy into mechanical energy. If it starts to fail, you might notice your lights dimming or warning lights popping up on the dash.
Sometimes you’ll even hear odd noises. We run full alternator tests with proper diagnostic gear to pinpoint the issue.
If you need a new alternator, we can replace it. Our alternator service covers:
- System voltage checks
- Inspecting and replacing belts
- Checking all wiring and connections
- Full charging system evaluation
Most alternator jobs take just a couple hours. We’ll test everything again after the work to make sure it’s all working as it should.
And yes, replacement alternators come with a warranty. Just for that extra peace of mind.
Battery Replacement
Your car battery starts and powers electronics when the engine’s off. In Thornhill, you’ll usually get 3-5 years out of a battery.
Signs that you’re about to have a dead battery include:
- Slow cranking when you start the car
- Random electrical gremlins
- Dashboard warning lights
- Swollen battery case
- Corroded terminals
We stock top batteries for all kinds of vehicles. Our battery service includes:
- Testing your system before we swap anything
- Disposing of your old battery properly
- Cleaning and protecting the terminals
- Checking the charging system
We make sure your new battery’s secure and connected right. That way, you avoid vibration damage and annoying electrical issues down the road.
Starter
The starter motor gets your engine turning when you turn the key. If it fails, even a good battery won’t help—you’re not going anywhere.
Common starter issues:
- Clicking but no engine turnover
- Grinding noises when starting
- Starts sometimes, not others
- Starter stays engaged after the car starts
We start with a full check of the starting system—motor, solenoid, and all the wiring. If you need a new starter, we’ve got you covered.
Most installations are done in a couple of hours, depending on your car. We double-check everything after the repair to make sure you’re set.
Other Vehicle Electrical System Services
We do more than just the basics. If it’s an electrical component we can fix it.
- Power window and door lock systems
- Interior lighting
- Dashboard lights, dome lights, whatever
- Entertainment system repairs
- Radio, speakers, touchscreen
- Climate control systems
Advanced Driver Assistance (ADA) Services:
- Backup camera problems
- Parking sensor calibration
- Blind spot monitor repairs
- Lane departure warning diagnostics
We also take care of keyless entry, immobilizers, and car alarms. Sometimes these security systems glitch out and need a reset or repair.
Plus, for newer vehicles, we do computer module updates and reprogramming. That can boost performance and fix known bugs straight from the manufacturer.
Signs Your Vehicle Has Electrical Problems
- Dim or flickering lights, including headlights
- Burning smell
- Trouble starting the car
- Dashboard warning lights
- Slow power windows
- Blown fuses more often than usual
- Battery keeps dying or dead battery
- Accessories cutting in and out
Dead batteries aren’t always old batteries. Sometimes the alternator just isn’t recharging it right.
If your power seats, mirrors, or windows suddenly stop, it’s probably an electrical issue—not a mechanical one.
Modern cars have a bunch of computers running everything. Weird stuff on your dashboard or entertainment system is usually a sign something electrical needs attention.
What Does Your Vehicle's Electrical System Control?
Your car’s electrical system does a lot more than people realize. It’s pretty much the backbone behind all the stuff that keeps your car safe and comfortable.
First up, it handles starting and ignition. No electrical system, no engine start. The battery, alternator, and starter all work together to get you moving.
Lights come next—headlights, brake lights, signals, interior lights. All essential for seeing and being seen, especially at night.
Don’t forget entertainment and info systems—radio, navigation, dashboard displays. All powered by electricity.
Comfort features like power windows, heated seats, and A/C are all electrical too. Kinda hard to imagine driving without them, right?
Then there’s safety systems—airbags, ABS, traction control. These only work if your electrical system is healthy.
And now, with all the new tech, you’ve got driver assistance features like:
- Backup cameras
- Parking sensors
- Lane departure warnings
- Automatic emergency braking
When electrical issues pop up, they can mess with more than one system at a time.

Real Stories in Thornhill, ON
"The staff at MR automotive are very professional and honest. When Bobby told me my air conditioning would be a little more expensive to fix due to the previous owner crazy gluing all of the lines together - I was happy to understand the situation instead of just being presented with a huge bill to replace everything. This isn't the type of shop where you'll be told to replace things prematurely or without proper explanation and proof - which is quite hard to find these days!"
Owen Wright
"MR Automotive is full of people who know their stuff but it's also great for people who aren't car-savvy (like me!) I trust Bobby & David to do a great job every time, they never sell me on anything I don't need, but make sure I at least understand what's going on. Thankful to have a mechanic I know and love."
