'94 Altima. Not sure what happened. They were working fine. My son backed the car out of the garage to get the lawn mower out. When we go to run an errand, the speedometer, tachometer, odometer, and temperature gauge are all dead. Checked all the fuses - no such luck. My son said when he was backing the car out, he went from neutral to park while the car was still rolling a bit (and he thought the tach might have died then). If it was just the speedometer/odometer, I would figure something in the cable from the transmission (is this still how they work? last time I had to bother with that was on my '76 Saab). But the tachometer has to be a completely different connection. Any suggestions?
