OK guys, I've got a problem. 1990 Ka24E.

I have the infamous non-functioning HUD problem, HOWEVER I also had NO lights in the dash cluster. The lights in the radio/HVAC controls worked, but the only thing working in the gauge cluster was the tach. The odometer didn't work either.

Fast forward to today. I got a spare cluster and HUD from another S13. I put it in before realizing that it was from a DOHC car, so the tach doesn't work. My own fault, however the HUD and speedo on the new cluster also aren't working. My question is this: are the speedometers also different between SOHC and DOHC cars? Or is there a speed sensor or something that is either bad or is different between the engines? The backlighting is working now, so that's OK. Don't know if the new odo works, I don't want to drive it until it's put back together.

To sum up: neither HUD nor speedo are working, even after putting in a new cluster. Everything else is, except for the tach, which I know how to deal with.

I really need help. My dash is all over the passenger floor right now until I get this resolved.

 

have you checked all your lines?

 

By lines do you mean electrical connections? Where would I check, other than making sure the plugs are secure in the rear of the cluster?

 

Shortened version: are the SOHC and DOHC speedometers different? Also, will the speedo remain completely blank if the speed sensor is bad, or will it read zero?
