Is there one relay that controls all dash board function?

Dash guages and turn signals.

Depends what year / model the car is, I suppose.

Also, I know the turn signals are linked to the hazard switch. If the hazard switch is sticky, or broken.. your turn signals will act rather funky. As for the gauges? The speedometer on the W123's is mechanical, controlled by a cable. The oil pressure gauge is also mechanical, with an oil line going to the back of it. The fuel level isn't on a relay, I don't think.. and goes to the sending unit in the tank. If you have a clock.. well, that just gets power. As for the tach (if you have one).. Um.. I'm not sure.. never really got a good look at the tach.

Best of luck to you.. whatever the problem may be.

When cold, the key will not activate anything but the starter motor and srs light. Turning the key back and forth 20 to 40 times and i may get everthing to turn normal...all lights, gp..etc...then all is well until the next morning.

I have the non tumbler portion of the ignition switch on order but I am replacing blind as I have not pinpointed the problem.

That's what I was thinking your problem was - the ignition switch
