What should I do today if the battery is dead?
Do not try to force the car to start repeatedly, as this can drain the battery further. Keep jumper cables in the car at all times, as Boise winter guidance recommends. Call a local pro to diagnose the battery at home before approving any work.
What should I check on the tires?
Check tire pressure using the pressure listed on the driver's door jamb, not the maximum printed on the tire. Pressure drops about 1 PSI for every 10°F drop in temperature, so a low tire is more likely in cold weather. Ask the pro to check the tire before you approve a replacement.
What should I ask for before hiring a mobile mechanic?
Ask for the full out-the-door price, including the mobile service fee and diagnostic fee. Published Boise examples show a $35 mobile fee in inner Boise, $50 in rural Boise, and a $100 diagnostic fee with up to 1 hour of troubleshooting. Ask for proof of insurance before work begins.
How can I prevent this next winter?
Boise guidance says cold can reduce battery strength by about 35% at 32°F and about 60% at 0°F. A seasonal-maintenance guide suggests handling battery and tire checks in October or early November, before temperatures stay below freezing.
What to do next
- Ask the mechanic to test the battery at your home before approving any replacement.
- Check tire pressure against the driver's door jamb reading, not the tire's printed maximum.
- Ask for a written out-the-door quote that includes the trip fee and the $100 per hour labor rate, if applicable.
- Ask the pro for proof of insurance and any relevant certifications before work begins.
- Call (208) 795-9673 or email [email protected] for a free quote from an independent, insured mobile mechanic.
