| + | = Dashboard Assembly Removal and Replacement = | ||
| + | You will need to remove the dash assembly to remove the dash pad, troubleshoot wiring, or to replace/lubricate the wiper linkage. Having the dash out makes changing the radio easier, but you can alternatively do that by only removing the glove box to gain access. It also much easier to install a tachometer after removing the dash, but again that could be done by reaching up under the dash. | ||
| + | |||
| + | |||
| + | It would be a good idea to label each wire you remove with masking tape. Write on the tape what the wire is for so that when you put the dash back in you'll know which wire goes where. This is especially important for all the green wires (flashers and brake-pedal wires). If you get stuck, see the [[Wiring]] article but beware the wire colors vary for differents years. | ||

| + | It's easiest to remove the entire dash (with gauges, radio, etc) '''after''' separating the wiring harness from the firewall. I've done it by removing wires from dash/gauges etc. and leaving the harness in the car, but it's much easier to separate the harness first from the car, then remove the whole thing. | ||

Nissan calls the dash assembly the "Instrument Panel". Both square-gauge type (Standard) and round-gauge type (Deluxe) are removed in the same way.
