While browsing I see that you have another thread about the oil light illuminating while on the freeway.
Left unsaid was what you did at that point. Continued to drive on or what?
I’m even more convinced the A/C may be a moot point and the least of your car problems.
So I looked and the fans and compressor don’t move. The fuses are all replaced. I wonder if the fuse box on the battery is bad. Iheard the wires in the box go bad so I am going to replace that.
The oil light went off. It was only on for a few seconds. I’m due for a oil change soon and it’s done this before when I was due for a change and it had gotten low.
You should not wait for an oil change to add oil if it is low. Low oil is the simplest easiest quickest way to damage your engine. Check the oil every other fill up, every other weekend or other regular schedule. Add oil if the level is at or below the fill mark on the dip stick. Oil is cheap, engines are expensive.
How low was it?
How long had it been since you checked the dipstick previously?
How many parts, probably unnecessary, are you going to throw at this without a proper diagnosis?
The Game of 20 Questions…
I fixed the oil situation and I don’t ever let it run low. And as for the diagnosis I have taken it in and paid a lot of money and they couldn’t tell me the problem. That is why I asked on here to see if anyone knew because the shop can’t figure it out and I didn’t want to pay a couple hundred dollars if needed.
I hope for your sake that the ultimate fix for your A/C turns out to be merely a couple hundred bucks. Unfortunately, on a car as old as yours it frequently runs into a LOT more money than $200.
Also, you could help other owners of Jettas if you tell us how you fixed the oil situation.
I’m not sure. I usually check it 2-3 times in between oil changes. And the light popped on and was off like ten seconds later and I immediately got more oil
If I could get a proper diagnosis I wouldn’t be asking in here.
How much oil did you have to add? If low oil was responsible for the oil pressure light, you are not checking it often enough.
An. HVAC specialist could not diagnose your problem???
Warning, I am going to be harsh

I think it is time we stop responding. The OP doesn’t answer the questions posed, nor check his oil frequently. He has repeatedly run his car low on oil. Says shop can not diagnose his HVAC system. How can anyone diagnose the system via the web?
well, you can always try this…
Window a/c instead of vehicle a/c - YouTube
I added 1 and a half q. And no they couldn’t.
I’ve answered all the questions and I don’t repeatedly drive it with low oil. I added a quart and a half so it still had enough. The shop told me I’d have to take it to a dealer. I asked on the web because vw are known for trouble with the ac so I was guessing maybe somebody had ran into this.
In 2008 I had a coworker with a 2003 New Beetle that had an electrical problem with the A/C and fan controler. One of the technicians inspected it (Dodge dealer), he was unable to diagnose the problem, rather than taking the car to the Volkswagen dealer for repair she replaced the car.
Some of these problems can be quite challenging but not impossible, you need to find the right technician.
pull out the a/c fuse under the hood. check the metal fuse tabs for corrosion. the fuse doesnt have to be blown for it not to work. also a common problem is for the cable to come off the climate control. so you can be turning the knob to cold and still be on hot. just some ideas. also there tend to be problems with the cables under the fuse box in the engine compartment.
maybe this will help
In regard to the lack of oil issue. You added 1.5 quarts but did not state whether or not that brought the oil level back to the full mark.
In regard to the oil pressure lamp you should keep this in mind. Most oil pressure lamp senders operate off of 3 to 5 PSI of oil pressure; meaning at 3 to 5 PSI the lamp will go out.
Three to five PSI of oil pressure will extinguish the lamp but that is not enough oil pressure to protect an engine. The only way of knowing what is really going on it to check oil pressure with an external gauge.
Mechanics often have different methodologies but considering the oil situation what I would do is check both oil pressure and engine compression as low oil levels have an effect on both.
My concern would be engine health over A/C operation.
