I just did this today. 1. remove the 3 plastic screws below glovebox. 2. remove plastic screw farther down under dash (after you do above, you will know what I'm talking about. 3. remove panel (all screws should be out now) 4. go behind dash and remove two nuts that hold radio in place. 5. push on radio from behind, and radio will come out the front. 6. Detach all connectors (about 8).
PS: I removed the negative battery cable just to make sure the power is off.
If you do it right, you can get it out in 1/2 hour without damaging your dash. Don't believe the people who tell you you have to take your dash out. The only panel that needs to be removed is the one below the glovebox, and it's pretty easy to do that without breaking anything.
WHATS THE TIMING MARKS ON 93 MAZDA 929
you have to remove the dash and every thing attached to it. Is it the same for a 1988 Mazda 929?
What is a timing cover seal on a 1992 mazda 929 and where is it located at?
929 1990 Mazda power brakes fails
well it's a very difficult job, so just take it to the dealer and $2,000 later you'll have it done! Don't forget to take a cup of coffee with you...............
Try powering the stereo up with jumpers to a power source. If the stereo still won't work with direct power check to see if it might have a anti theft stereo. If no then replace the unit. If it works with jumpers then look for a break in the wire or a bad fuse. Easiest fix in this case would be to run a new wire from the fuse panel, (key on power) to the stereo. These cars are known for stereo problems, my daugher has an 1989 929 and the stereo dies for days and then works if someone turns it off by accident instead of just turning off the volume...
In Canada traction control was optional on the 929.
originalkeyless.com they have the remote and the programming for Mazda 929's
Wheel hubs or bearings or could be the CV shafts.
From memory there are to 10mm nuts holding it in place. The nuts are located behind dash just above the transmission tunnel. possibly 100m above the trans tunnel. I dont know if they are able to be seen but I remember standing on my head for a while trying to find them. Just feel around behind there. Good Luck. Lee Tulloch
