What is your engine?

Your ac relay is in location one, very top left relay, Take it into auto zone and have them test it, or test it yourself if you have the knowledge, im attaching a link to the under dash fuse box diagram http://faculty.ccp.edu/faculty/dreed/Campingart/jettatech/fuse_block.jpg

Hope this helps

Sounds like a ground is loose somewhere, Electrical problems are hard at that point especially when it is a ground because there is no 12v currant to chase. Ground wise, they are all easy to find on this car, Two are under the battery tray, one ground bolt will have 5 wires, the other two, the others are on the corner of the valve cover (drivers side), The drivers side on the "dash Bar"( the bar that your dash mounts too) and on the front of the block toward the passenger side Good luck

lock your door and hold the key in that position, and then turn it the other way and hold it until they roll up, this should set the alarm back. If that doesnt work try replacing the radio with the stock one, your third option is to bypass the alarm module.

If you have a basic knowledge of how electrical works and how a starer system works you can create a basic and simple circuit using your stock ignition switch to bypass everything stock and if you have an alarm this will still allow you to leave it intact.

Alarm box is behind the abs light panel and headlight switch, Its kind of hard to get to but there will be a 6 pin and a 10 pin, the other box is for the headlights, unplug the 10 pin harness and pit a jumper wire from the red wire to the red/black wire. Alarm is bypassed

A local Checker or Auto zone can help you with that, but if you have a failure that is not corrected, the light will come back on.

That is the engine oil cooler. There is a 'O' ring between it and the oil filter mount. They harden and crack.

Ask your dealer for the large Oil Cooler 'O' Ring.

Remove oil filter. Remove exposed pipe nut holding oil cooler to housing. If nessacary, drain coolant so you can disconnect coolant hoses from cooler or catch coolant as hoses disconnected. Swing oil cooler away and remove old 'O' ring.

Place new 'O' ring with grease on oil cooler it to hold it in place and reassemble. Tighten oil filter pipe nut to around 18 ft lbs .

Refit oil filter. Refit coolant hoses and top of oil and coolant.
Run engine to check for leaks and allow to cool. Top of coolant to COLD level if required.

You will need hose clamp pliers and wrench for oil cooler pipe nut. Pliers can be obtained from most parts stores.

either emissions conrols are screwed up or the computer needs reprogramed to factory presets.. has a tune-up been done recently..fluids/filters changed..

run fault codes and look for cam/ rank position sensor problems. Check that the cam shaft is moving and that the timing belt is not broken. Ensure that the immobiliser is operating correctly

Computers have eliminated vacuum advance as a means of advancing timing. If your car has a computer, whether carbureted or not, the computer should control timing.

replace clutch and throughout bearing

transmission code for my 1999 VW JETTA , WOLFSBURG EDITION COULD IT BE DLZ. 2.0L

Hello
Code is engraved on a plate on the side of the transmission it self and usually it is a 3 letter code.

check your spark plugs or ignition switch or fuse or the connections in the engine which sup[ply fuel to the plugs

If your temp seems to come down when idle or at a stop, it is most likely the water pump.

VW has a known problem with the water pumps breaking. The plastic impeller on the water pump fails cracks.

Do not let your car overheat to the red line, once it beeps, turn it off. Other wise it can damage your engine. In fact watch the temp gauge, as you drive when it gets near the red line turn it off.
Turning your Heater on full will help to cool your engine.

My water pump made it to 84000 miles. I have a 2003 Jetta 1.8T Wolfsburg
At which time my timing belt, thermostat and water pump was all replaced. This saves on labor.
The water pump is driven off the timing belt. So while they are in there get that done.

Your owner’s manual has a Maintenance schedule list, your timing belt should be replaced at something like 60000 miles or so, I am not exactly sure of service schedule as I do not have it in front of me. If your getting your timing belt done, get your water pump replaced to. It will fail eventually.

As for over heating?
When is it over heating?
If you read the Owners manual it clearly states in there these cars run hot, do not let it idle for a long period of time. In the middle of summer in Fl, while sitting idle for long periods of time in traffic with the air conditioning on, my car will over heat a bit. This is normal.
Most people like to start their cars and let them warm up, this car you don’t let it warm up, and again the owner’s manual has this in it.

As for coolant, do not use water or green anti freeze, use G12 (it is red, pinkish) which you can find at Napa, or a Mercedes, VW dealership, in a pinch to top off the coolant you can use Dex Cool, not ideal but it works as G12 is not easily found at wal mart or AutoZone type places, I couldn’t find it there? The people at AutoZone told me Dex Cool is the same as G12, my mechanic says it is not the same. Close but not the same. It will do to top off the coolant.

Usually a stuck relay.
