SPEEDOMETER DOESN'T WORK AFTER HAVING THE CLUTCH REPLACED

Mazda do not make distributors or electrical connectors . These parts are made for mazda to mazda specifications by electrical manufacturers / contractors . So being aware of that it is possible (long process) to get the name on the distributor to Lucas-Nippon denso -nitto -Mitsubishi-( Mitsubishi make for a lot of different car makers as oem equipment) etc and any other details stamped into the body of the distributor or ignition module and contact them on the web site at the technical section or parts section and try and track down from there. Another way that I sometimes use is to cruise the wreckers (mazda in this case ) and look for distributors from other engines that will have this part in use as there is always a parts over lap where new products are fitted to the run out models before the new model is on the market

You could try this page: http://www.partsgeek.com/ymm/1993/mazda/mx6.html?sort=pop&scat=engine_electrical

Without knowing the name of the part you could look at the different connector and match one up. Good luck!

If the shop that installed the clutch also replaced the hydraulic system, I would take it back to them.
If they only replaced the clutch disc and cover, the master cylinder or slave cylinder may have failed.

When my MX6 was doing this it turned out to be an hydraulic leak from the clutch master cylinder, which runs on the same fluid reservoir as the brakes. Clutch master cylinder replaced and all good again!

Easiest solution would be to pull the fuse, but if you do that your air bags won't be in working order. A flashing light is usually a sign that a relay is out in that system and it isn't working anyway. Your fuse panel will show you which fuse it is.

depends if the bolts are seized ,just cut them off if they are ,hardest part is jacking vehicle up

It's easier to remove the engine but if you have a hoist and good gears you might get away without removeing the whole engine.

you need to replace the board behind the cluster i haveone they are no longer found at the dealer if you email me i can see if its the right one

did you try replacing the ignition module?
every time that happened to me, it was exactly that. I have found an inexpensive way of repairing this.

Go and buy yourself a workshop manual (Something like the Gregories manuals sold here in Aus) and for the 50 bucks it'll cost you, you'll have yourself a good cheap car. A good manual will show you step by step how the job is done and you can have it there with you as you go.
