# Starter Motor Repair in Upland > Clicks, grinding or a slow crank? Route 66 Auto Repair in Upland tests the starter circuit first, then repairs or replaces the starter motor. Source: https://route66autorepairshop.com/electrical-services/starter-motor-repair Updated: 2026-09-17 Business: Route 66 Auto Repair, 1775 W Foothill Blvd, Upland, CA 91786, (909) 608-7699 Hours: Monday to Friday 8 AM–5 PM, Saturday 8 AM–2 PM, Sunday closed **TLDR:** No-crank problems often start with **cables or connections**, not the starter. We test the whole **starting circuit** before we quote a part. When you turn the key and get a click, a grind or nothing, the starter motor is a likely suspect, but not the only one. Route 66 Auto Repair in Upland tests the battery, cables and starter circuit before we replace a starter, so you pay for the actual fault. We accept tow-ins, and our after-hours key drop means you can leave a car that will not start and hear from the counter once the vehicle has been tested. ## Signs your starter motor is failing - A single loud click and no crank. - Grinding or a high-pitched whirr while cranking. - Slow, labored cranking with a battery that tests good. - It starts on the second or third try, then fine for days. ## What a starter repair actually involves The starter is a strong electric motor with a solenoid that pushes a small gear into the flywheel ring gear. It draws more current than anything else on the car, for a few seconds at a time. That makes it sensitive to weak batteries, corroded cables and poor engine grounds. When the starter itself has failed, most shops, us included, replace it with a new or remanufactured unit rather than opening it up. We also inspect the flywheel or flexplate teeth, because a chipped ring gear will chew up a new starter quickly. ## Our starter repair process 1. **Test the battery:** A weak battery is the most common cause of a slow crank, so we check it first. 2. **Measure voltage drop:** We read the loss across the positive cable, ground and starter circuit while cranking. 3. **Check the controls:** We confirm the starter is getting its signal from the key, relay and safety switch. 4. **Replace and inspect:** If the starter failed, we replace it and inspect the ring gear teeth while it is out. 5. **Verify:** We crank the engine hot and cold before returning the car. ## What's included in starter motor repair - Battery state-of-health test - Cranking voltage drop test on cables and grounds - Control circuit check through the relay and safety switch - Starter replacement with a new or remanufactured unit, as approved - Flywheel or flexplate ring gear inspection - Hot and cold start checks after installation ## Can starter trouble wait? **Need now:** - Grinding that means the gear is not engaging cleanly - Intermittent no-starts when you depend on the car daily - Any burning smell or smoke while cranking **Need later:** - A slightly slow crank with healthy test results - Cleaning light corrosion at the cable ends ## How pricing and timing work The counter states the diagnostic fee before testing, and it applies to approved related repair. Starter cost depends on the part and its location: some bolt on from above, others sit under the intake or behind exhaust parts. The written estimate spells that out. If you have a hybrid, tell us it is a hybrid at intake and we will explain what we can take on, since many hybrids start the engine without a conventional starter. ## After the repair Crank normally and avoid holding the key more than a few seconds at a time. If the engine is slow to fire, that points to fuel or ignition, not the starter. Ask about [ignition system diagnostics](https://route66autorepairshop.com/electrical-services/ignition-system-diagnostics) in that case. You can also book a [starter motor condition inspection](https://route66autorepairshop.com/diagnostics-and-inspections/starter-motor-condition-inspection) before a long trip. ## Frequently asked questions ### Is it the battery or the starter? A clicking sound with dim lights usually points to the battery. A single click with bright lights often points to the starter or its solenoid. We test both, plus the cables, so the diagnosis is not a coin flip. See [battery testing](https://route66autorepairshop.com/electrical-services/battery-testing) for the battery side. ### Can you tow my car in if it will not start? Yes, we accept tow-ins. Call [(909) 608-7699](tel:+19096087699) so the counter expects the vehicle, and use the after-hours key drop if it arrives after closing. ### Do you repair starters or only replace them? In most cases a new or remanufactured unit is the practical choice. If a separate solenoid or relay is the problem, we replace just that part. Your written estimate shows every step. --- Call (909) 608-7699 or visit https://route66autorepairshop.com/contact for a written estimate.
