Question about 2004 Mazda RX-8

Car will not start

We started having an intermitent problem with the power stiring motor, after taking the car to the Masda dealer they determined that the motor was going bad and it would take 900.00 dollars to repair. We dicided to wait and discovered that part of the electrical components (a/c, power window, radio ) would not work and the car would not start or turn over. I found the 120amp main fuse on the fuse block was intermitent and that if you put preasure on one side of the fuse there was arcking and those electrical components would start working again, including the power stiring motor.I replaced the 120A fuse and the car started working again. I thought my problem was over but after a week the problem came back and now is not the 120A fuse, it seems that the problem is after the fuse. another thing that i notice is that the fuse block inside the floor board has no power. can anyone suggest a good source of electrical wiring diagram or an idea of how to correct my problem!

    remember that the a/c blower not work and there is no power to the inside fuse holder. the 60A fuse neer the batery is good as well as the 120A main fuse on the under the hood fuse block.

You can find the service manual with wiring diagrams for your car from here:

It looks like the wiring is faulty/burnt out and you may need to replace some of them.

Is there a way to reset electronic throttle control light on 08 Chrysler town and country after it has stalled and wont restart?

No. There is not a scan tool can't either the pedal is not hooked up to engine with a cable. All computer analog signal with electrical wires. This is not one for most mechanics to diagnosos . they seem to have a issue with it. Anyways, take it to dealer. The pedal uses two sensors with oposote signals to determine position. The computer controls electric motor on engine that opens and closes throttle vale. Computer uses two sensors in throttle body to determine its position. If any of these four signals carries even slightly, nothing more than idle. Some will start and idle with no pedal response and other will stay at idle if engine was already started and once keep shuts off then won't restart. So take to dealer.

99 accord stalls turn off car wait minute it starts back up no problem

have the ignition switch checked....When the vehicle stalls while in motion, does the speedometer go to zero?? Shake your key while the engine is started and in park position....See if it stalls?? If yes possible faulty switch!! The switch has been recalled by honda since 2002....The internal connection that provides power to vital electrical parts shorts or has excess wear due to poor design. In this case power fluctuates and the motor stalls and other electrical parts shut off intermittedly. Call your local honda dealer to check if your vehicle is part of the recall, they may need your vin#. Hopefully this helps
