1989 Mazda Protege Speedometer and Odometer stopped working

Ok first off I do need to know what year it is there was no protege in 89. Get back to me with that and I will happy to try to help.
If it is a 98 protege then I would check the vehicle speed sensor or VSS. If you have a digital multi meter then get back to me and we will do a test to see if it is that or the speedometer sensor on the back of the instrument cluster. Thanks for your support.

Car was purchased in 1989, but I think it's a 1990 model. I'm not near the car to double check.

I hope this helps.

Ok this does change things as not you have a speedometer cable. I would undo it from the transmission and check to see if the cable will turn you can hook a drill to it and manual spin the cable and see if the speedo moves at all it not I would unhook it from the speedo and do it again if the cable still dont move then replace the cable. This is also why you have no odometer they work together. Hope this it more helpful. Thanks and have a great day.

Thank you, I will give it a try.

About my Hold light problem.

The hold light flashes on and off.

There is no problem with normal shifting. It's just that the hold feature does not work. I don't use this feature anyway.

Is there any real concern? I can live with the light flashing on and off. As I said, the car drives fine.

Ok that may have something to do the EC-AT module. So if you have a digital multi meter and can make a jumper wire then we can first pull codes from it and then do some diagnostics. So first you need to make a jumper wire and ground the single pin connector and turn on the key and count the flashes of the hold light as it will flash in numerical sequence the code numbers to you. Lets say it gives a code 11 it will flash 1 short pause and flash 1 then longer pause and on to the next number ok. Get the codes to me and we will go from there. Here is where the connector is and what it looks like.
