tach stopped working

[n240sxfnatic]

Ok so I was driving home last night and when I was pulling away from a stoplight I noticed that neither my stewart warner nor my stock tach was working, the speedometer was though. I started the car this morning to find the same thing. My question is where do I start. Is there a connection I should check somewhere?

sterwart warner???

check lower harness to make sure it's plugged.
check continuity on wires.
Pull cluster, clean contacts, make sure everything looks right.
Try someone elses working cluster.

FSM has the cluster pin out. you can find the relevant wires there.
I'm assuming this is not HUD right? HUDs are known to act up mostly from old age.

there are some connectors on the transmission. Make sure theyre, uh... connected.

I had my reverse lights go out when i bought my car. 2 1/2 years ago. I only fixed it last week.

Check the relays behind your drivers side fuse panel. Sometimes they like to come loose, ..I had the same thing happen once before.
