Shocks or bushings and/or suspension worn

what is the problem ?

sounds like you have a failing ecu. the capacitors in the ecu are worn out. there has been a lot of problems with the ecu on mazda's over the years, only take one out put overload from the alternator and the ecu starts playing up. no codes come up as it don't code its self. having the battery off is like a reset.

sending unit / fuel could be going bad or the fuel stock filter is getting pluged up when stir up the gas in the tank the sock is a filter inside the gas tank over the sending unit try changing the fuel filter out side the tank that could be pluged up.

Probably the master switch.The other door switches work independently from the master.

The 'freeze plug' is in the block, front and back, not the head.I is a disk if thin steel that is an interference fit and will knock out to be replaced without dismantling the engine. The correct name is Core Plug.

When you ran a test lead from the battery, did you run a separate ground wire to the bulb? If yes -- confirming no ground from the original lamp connection -- try inspecting the body ground closest to the lamp: Remove, clean w/ wire brush or steel wool (both the connector and the nut/bolt holding it to the body), then try again. If still no luck, check ALL the body grounds in the engine compartment. If there's still no ground, try using a "quick splice connector" to connect a grounded bypass cable to the original grounding cable, near the lamp. (These connectors can be tricky. Instructions say you don't need to strip the sheathing on the cables, but I usually cut the sheathing with a knife to make sure there's a good connection.)Regarding HID lamps: for running lights, do the main headlights come on w/ reduced power, or is there a separate lamp? If it's a main headlight, maybe there's an issue w/ a step-down transformer, or whatever system is used to dim the lamp.

Ask Mr Mazda what is wrong as it must be something to do with the Heat of the day or He did something so as he can make MORE money from you. Next time Rotate the tyres yourself as it will only take about half hour and cost nothing. You can than SHOUT yourself a few BEERS this the money you saved

Thats pointing towards the throttle body sensor.

Open the door from the outside and then take off the inner door panel to find the problem. It is usually the door handle that is broken.

Either a bad key or a bad sensor in the dash or where the key switch is that is not getting the signal from the key.

Bleed the clutch fluid to remove the air from the system. Make sure there is no play in the bushes of the gear linkages
