2008 saturn aura change the radio because the aux cord was messed up So i ordered another stock radio and plugged it in and it didn't turn on or anything put the old radio back and it worked just fine

Edgar, Strange old radio is fine now, maybe it was just a bad connection or ground. New radio maybe had to be programmed with a code to get up and working. Not sure ?

Can and how do you reset the tps switch on a 2005 pathfinder auto tranmission?

The tps (throttle position switch), comes preset from the factory. It shouldn't need any adjusting unless someone played around with it. On Toyotas they are security marked so you don't touch them because then you loose your warranty.
If you just want to reset your ECM(computer) then the easiest way is to disconnect the battery for a few minutes, but remember that you will loose the radio security code so you will need to know your radio security code beforehand. I think another way to reset ECM is to remove the fuse marked ECM or CCM or something similar for a few minutes.
After reseting ECM, turn ignition switch to the ON position (Car OFF) and depress accelerator all the way to the floor TWICE. This will recalibrate throttle position switch. Well that's how you do it on Toyotas anyway.

Radio and blower fan stop working

Probably a blown fuse or a miswire. Pull the radio and revert to stock. If the fan works carefully re-wire the radio with a good diagram.
if the fan is still dead with stock radio setup you may have a short, bad relay or bad temperature switch.
if you understand electrical get a tester and start snooping.
see if any of the manuals contain good wiring diagrams.
if not its best to leave it to the pros. You dont want your car to go up in flames. If you are super concerned about a fire, disconnect your battery when the car isnt in use. SpoonerTuner com Free downloadable Honda Acura Factory Service Manuals...

Radio not working

there are 3 power sources to radio. if stock, if not stock more.
Radio power.
memory power
and dial lamp power. (dimmer)

why not use a voltmeter to find out why its dead.
even better the FSM shows the wires, the colors and the path.
making guessing go to zero.

when working electrics pull battery minus lug, like the FSM directs you.
and keys in pocket. causing load dumps can cause very expensive
electronics to fail. even the EFI, PCM.

Stock radio works but no sound tested speakers and they work what could it be?

The stock harness was butchered, possibly to allow the separate amplifier to be bypassed. My guess is that the stock amplifier is still in place but not connected to the radio.

How do I reset Change oil light

The reason that you can't get the pressing pedal three times to work is because you took out the stock radio. When you take out the stock radio you mess with its programing abilities. I hope you kept the stock radio because if you ever need work done to your car that involves programing certain things like your cluster you will need your stock radio back in it for it to work

Where the brake switch on my polo 3003 model my brake lights dont work some told me its the switcc

Check & replace if necessary the brake pedal switch placed above pedals on the support.
If the problem still occurs you might access the ABS ECU (Electronic Control Unit) using diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored.
Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC stocked inside ABS ECU & reset it.

1. Remove the cover panel above the driver's side foot well ...
2. Locate old switch, push in brake pedal, and twist switch body to remove ...
3. Unplug 4 pin connector from old switch and plug into new switch (it only goes one way...don't force it!). Insert new switch into frame and depress brake petal. You should turn it until it locks into place and is positioned like the original.


4. Start the engine. Press the brake pedal once or twice and the EPC light should go out ...
5. Replace the cover over the foot well and you are done! If not, check the 4 pin connection and make sure it is fully seated in the switch. Also check to see if you can hear the switch engage when you press the brake pedal ... if not, you will need to remove the switch and adjust the push rod. The rod will move in and out for adjustment. Check to see if the brake lights come on when you press the brake pedal as well!
