I have a Aiwa head unit in my 2002 volkswagen jetta 1.8t, the power is on but no music is playing from the radio or from my phone. I checked my fuse box but it doesn't have the guide that tells me which fuse is which what should I do to fix the problem?

SOURCE: 2002 dodge grand caravan--radio cigarette lighter power out

there is another fuse box under the dash on the driver side. if you have your manual, look up the fuse positions in it and find the proper fuse. if i read your ad properly you have no power to the radio or cigarette lighter. this circuit is on one fuse in the fuse box under the drivers side dash

There should be a connector under each seat which connects power to the heating element. It is likely either clipped to the seat or tucked under the carpeting. You'll almost definitely need to remove the seat to get easier access to it, though it should be possible to find/access it without removing it, just more difficult. Once you find it, disconnect it. You can use any multimeter with a continuity tester to test the circuit. First, check the DC voltage coming from the wires that come up from the floorboard. If you are getting voltage there, you will want to check continuity of the element itself by probing the two wires with the meter set to it's continuity testing selection. If there are more than two wires you will need to determine which is the common wire and which are the "live" wires. With the power disconnected you can test the element to figure this out easily. For example if your heated seat has three wires, test all three for continuity in pairs. If one wire always shows continuity no matter which other wires on the same plug you touch that should be common.

If the element tests good (in other words you find that all the circuits show continuity) and you are getting power from the plug that comes from the vehicle itself, you might need to check the resistance of the element. It is rare to have a bad element that still shows continuity, but it is possible that the resistance may have for some reason become lowered and the element therefore does not heat up.

Try these and let me know how it goes!

SOURCE: 2002 Jetta TDI radio fuse number?

The Fuse number is..... drum roll..... 42 .... And you don't even have to have a dead battery for the radio to lock up. I have owned my 2002 tdi since New... and about 4 or 5 times a year radio dies. When you remove the fuse... don't immediately put it back in.... The capacitors in the radio have not fully discharged and if you put the fuse right back in.. chances are it will stay locked. I count to 15... then put the fuse back in. Close fuse door.... Operate radio normally till next lock up.... then repeat process. So you won't forget the fuse number... write #42 in the white space of your fuse location sticker that is attached to the inside of the fuse door. Hope this helps... tried to be detailed.

SOURCE: my epc light went on in my 2002 volkswagen jetta

Take it to the dealer, the EPC warning light - and even more the failsafe run which doesn't allow you drive faster than 20mph) is an indication of serious motor troubles. They can read the ECU faultcodes, which should be a good startingpoint for troubleshooting the cause ...

You could do some basic troubleshooting like checking the air filter, the oil level, the spark plugs, etc. You didn't fill it up with bad gas, did you ? And does the engine make strange noises/vibration when running idle ? In case you fixed some obvious cause, you can dis- and reconnect the battery to erase the engine's faultcode. If it's not fixed, the EPC (and failsafe run) will simply come on again.

My advice would be not to drive it untill it's fixed to prevent more potential damage.
