2006 Nissan 350Z 9000 miles
I can't get my windows to work. Bought this as a project car, dude gave me new switches and said everything worked when he parked it. I put in the new window switches, that didn't work. Put in new window motors, that didn't work. I Think it might be an issue with the wires, but I haven't been able to find what the issue is. If anyone has a wiring diagram that would be great. The gas gage and speedometer also do not work, but they light up.

Here’s what’s likely going on and what to check next:
⸻
Why It’s Happening
• The ABS module provides the speed signal to both the cluster and the traction control system. • If that signal isn’t reaching the cluster (due to a disconnected wire, blown hidden fuse, or short), the cluster stays at 0 mph, ABS & TCS turn off, and the SLIP light comes on. • The radio harness on a 350Z runs right by some CAN bus wiring — if a wire was cut/spliced wrong, it can break communication to the cluster. • Battery disconnection can’t cause this alone, but if something was already loose or was bumped during the radio install, reconnecting the battery could make it show up.

What to Check
1. Check the ABS Module connector
• Located in the engine bay, near the brake master cylinder. • Make sure the plug is fully seated and no pins are bent. • If the ABS module is unplugged or not powered, you’ll get exactly these symptoms. 2. Inspect radio wiring
• Remove the head unit again and look for:
• Any twisted orange/orange-white wires (CAN lines) that were cut, left open, or grounded. • Any black/yellow (ignition) or constant 12V wires tapped incorrectly. • The speed signal wire can also run through here on some trims (light green or pink depending on year). 3. Check the smaller fuse box (IPDM and cabin fuses)
• Even if the main fuses look fine, check:
• Meter fuse (10A)
• ABS fuse (10A/15A)
• ECU fuse (10A)
• Sometimes a small fuse that doesn’t look blown will still fail under load — test with a multimeter. 4. Scan for codes (ABS & ECU)
• Even if the CEL isn’t on, your ABS module may have stored a communication or speed sensor code (like C1101 or U1000). • This can point to whether the issue is a bad sensor or a wiring/communication fault. 5. Wheel speed sensors
• If one sensor fails, you normally still get speedometer readings (ABS just disables), so since your speedo is dead and all lights are on, it’s more likely a wiring/power issue, not just one bad sensor.

Most Likely in Your Case
Since it happened right after the radio wiring fix:
• A CAN wire or speed signal wire in the radio harness got disconnected or shorted. • The ABS module fuse or METER fuse blew during the wiring job (and looks intact visually but is actually open).
