A good place to start is your owners manual. Baring that, on most cars, the power outlet is usually fused from the fuse box located in the engine compartment. (Hot all the time). Remove the box cover and (usually) the box cover has a listing of all the fuses on the inside.

Hello! "Bentley Publishers"is the only manual that shows fuse positions...However here are fuse location diagrams: This is as large as system will accept, let me know if you can zoom in...Guru...saailer

Heed of antifreeze coolant temperature!!!
First time you might check the thermostat operating.
The thermostat location for VW Jetta 1.9 TDI - AJM engine, is on back of the alternator at the bottom side of the bracket.
IMPORTANT: It is NOT necessary to replace the alternator if you want to change the thermostat !!!
Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 60 Celsius Degree you still warm up the engine until the lifter (pointer) reach 80 C deg. (second mark after 60 C deg.). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 90 C deg.
3. The thermostat opening temperature is 87 C deg.
4. If the hose is already warm the thermostat is out of order.

Thermostat location, Part number: 044121113, in german - "Kuehlregle" (Price around $25):



Important note: Always replace the thermostat seal, position 7 in the above picture.

Please do rate my response. Thanks!

The exact locations and picture of Engine Coolant Temp (ECT) sensors on 2004 VW Jetta TDI:

1. ECT sensor 1 placed on cylinder head:




2. ECT sensor 2 placed on the left bottom side of the radiator:

follow the top hose on the radiator to the engine where it connects to the housing inside the housing is the thermostat

It's located near the cam gear on the front of the engine however, the crank sensor, to the right of the oil filter near the bell housing is the part notorious for going out on these cars, and causing a p0322 and/or p0341 code, and sometimes others as well To replace the crank sensor you have to: Support the motor with a floor jack. Remove the starter, 2 of the starter bolts connect to the motor mount. Remove the motor mount from the frame, very easy. Remove the oil filter. That will give you just enough room to get an allen wrench in to remove the bolt holding the sensor in.

one is located over the battery, the other is located in the side of the dash.

First panel:
If you pop your hood the battery will be on your right sid in the front of the engine bay. There is a small rectangular piece on top of the battery with a lot of heavy guage red wires going to it. That is the engine bay fuse box.

Second panel:
if you open your driver side car door it's under neath a panel located inbetween the door and the dash board.

follow the top radiator hose to the engine and the dome looking end that the hose connects to is the thermostst housing remove the two or three bolts from that and the thermostst is under that
