M&J Auto Electrics has worked from the same Pitt St, Merrylands workshop since 1980. Most of our customers come from the surrounding Cumberland and Parramatta suburbs, but we regularly see drivers from right across greater Sydney — especially for Smart Start interlock installs and hard-to-find electrical faults.
Find your suburb below. Everything is done at our workshop at 173 Pitt St, Merrylands NSW 2160, open Monday to Friday, 8:00am–4:30pm.
Merrylands 2160
Our home suburb. The workshop is a two-minute walk from Merrylands station and the shopping centre, so you can drop the car off and get on with your day while we diagnose and repair it.
Merrylands West 2160
Just a few minutes from Pitt St. Bring in warning lights, flat batteries or air-con that’s stopped blowing cold, and we’ll give you a straight answer before any work starts.
Granville 2142
Our neighbours to the north-east. Granville drivers come to us for electrical diagnostics, starter motor and alternator repairs, and air-con regas from $170.
South Granville 2142
A short drive from the workshop. We look after everyday cars and commercial vehicles alike, from charging faults to lighting and accessory fit-outs.
Guildford 2161
Right next door to Merrylands. Whether it’s a car that won’t start, a central locking fault or an airbag light, we’ll find the cause with professional scan tools.
