I have a few, if you need a new one let me know
I don't know how the rpm meter works on your car but new cars use a Stepper Motor to turn the needle. If yours has a stepper motor it could be electrical problems, fuse, wires broke, etc. If it's the stepper motor you might need to replace it. I'm guessing but I suspect you need to get the dash off to work on the back of that gauge.
bad cluster motor, burnt out traces on the cluster.. number of possible causes.
Hi, I have the cluster out but how can I tell if it has a stepper motor?
Would you happen to have the back plastic trim that covers the instrument clover? Thanks.
Thanks for the videos.
I have complete instrument clusters. Not 100% sure what you mean by cover, but I may have it.
The question came up in this thread about the rpm hand. There was a posting about issues with this Tach and the problem may have been resolved.. For the '91, 1.9l engine the Haynes repair manual shows the Tach is driven off a computer. It doesn't show the details of the Tach so it could be an analog voltage or digital pulses. It looks like an analog voltage fed to the inside of the Tach and that would have a needle on a meter similar to the old type of voltmeter. The other end of the supply voltage to the Tach comes from a fuse. If you replace the Tach and the new one doesn't work you probably have a wiring problem.
Thanks. I replaced the cluster. The tac now works. Thanks
Hi and thanks. I’m not sure what it’s called but it’s the part of the dash (black in color) that you have to remove the screws from and then remove it in order to get to the cluster as the cluster sits behind it. Thanks.
