Ever since my driver’s side central locking mechanism self destructed I’ve wanted to either find a replacement part to fix it or come up with a better way to accomplish the same functionality. After viewing a YouTube video about installing a keyless entry system I decided that such a feature would do just that.
To make this sytem work I needed to find two new parts:
- A linear actuator to actually move the door lock. Volvo makes this already (part no.1315178) and thankfully they are widely available on eBay which is where I got mine.
- A controller kit. China makes billions of these and they’re all basically the same with the main difference in the number of buttons on the key fob. I just needed one for my doors, so I eventually settled on this one from Amazon.
With my parts in hand, I set out to put it together.Continue reading
Now that the dashboard was off and the new blower was installed I could turn to the ignition issue. I had proved that both the starter motor and the engine itself worked, so the issue had to be somewhere between the key and the starter. I looked around on the forums and saw it suggested that the most common cause of what I was seeing is a broken neutral safety switch. This is a simple switch connected to the gear selector that prevents cranking when the car is not in park. Unsurprisingly the switch itself is located in the gear selector housing. The entire assembly is a sort of wedge shaped plastic bit that is connected to the gear selector by a plastic lever with a hook on the end. When the transmission is in park the lever connects a circuit that allows current to flow to the starter. When it’s not, the circuit is broken and no crank. I undid the two screws holding it in place and lifted it out gingerly. Once on the bench I prised the tabs holding the metal cover on and took a look inside.Continue reading
