Passat (B5) :: 2003 - AC Just Randomly Stopped Working - Pressure Switch?
Jun 8, 2010
My sister has 03 wagon GLX and her a/c just stopped working one day. It was a few months ago and I remember when it happened that I scanned w/ VAG-COM and it gave some sort of pressure switch code - can't remember if it was low or high, but at time she wasn't concerned w/ it ($$ was tight). Unfortunately, I saved info on my laptop and can't find the document now and the car isn't throwing the code any more (I tried turning a/c on several times).
It sounds like a pressure switch to me, but not sure what the part would be (or where it is located on car). Any tests I can perform to confirm this? Also, I see two listed on ECS and they're nothing alike

My fog lights were working on second then all of a sudden both of them stopped working. And the switch on the inside isn't turning green when you pull out to turn them on. What the deal with that and how I can fix it. I just switched the bulbs today but they were working but just stopped.

Just picked up 2010 2.0 T GTI. Horn was working fine up until today. Just randomly stopped. Could it be that the horn goes that abrupt?
Checked the fuse, it's good.

So a couple days ago my key fob randomly stopped working. I search around the internet and found a youtube video describing how to replace the battery. I used a CR2032 battery. However, my keyfob still won't unlock my car.
Unfortunately, I bought it used and didn't receive a manual key with it (derp moment, I didn't even know there was one!) so I have no idea if it would even start my car. When I replaced the battery the red LED light flashed for maybe 10 seconds then stopped. It then doesn't flash if I hit lock or unlock.

I have a 2003 Passat 1.8T Wagon.
My passenger side, front window and lock stopped working. Once I cranked the AC and the car cooled a bit, the lock and window would work again.
Now, they have stopped working completely.

Driving home from work today, normal day in the high 60s, my temp gauge randomly stopped working. It was right at the 190 mark where it should be then a few miles from my house it just dropped to 0. When I got to my house and turned it off the fans stayed on for quite a few minutes.
I went inside and looked around on a few different forums. Most people said it was the thermostat or some sensor that could have crapped out.
Probably 30 minutes later I went out to restart it hoping the problem magically disappeared and it actually did. Start up and went straight up to 190 as it should. Turned it off to no fans as usual.
What this could be? Could it just be a sensor on the way out? Still under warranty so might try calling the dealer tomorrow when they open to ask for their input.
Just as reference my car is a 2011 with about 48k and is revo stage 1 for about 3k.

My driverside headlight randomly stopped working last night after i came out from a restaurant. the driverside was off the most of the ride home until it flickered on. now it randomly will only turn on for a split second then shut off.
i recently had my headlight / front bumper replaced and i was wondering what could cause this? normally if it was hid instead of led i would say its a weak ballast or so but i do not know how the LED headlights work. also the car is too new to have a weak ballast.
i do not believe its a fuse because the headlight will not turn on at all if it was a fuse. i also checked the box and all the fuses look intact.

I have a 06 GX470, and the lf window master switch has stopped working. The only items it will still control are the window lock, and the up and down movement of the lf window. It will not operate the other three Windows or the door locks. I did try to re-sync all of the Windows first. I know the master switch is good, since I was able to swap it with a known good one. I checked all fuses and they are also good. I removed of door panel and was going to start checking grounds and continuity between the harness from the lf master switch to the junction block.

So my car is just under 2 weeks old. I had the car tinted today and now the drivers side window switch will not operate the passenger side window. The switch on the passenger side works fine and the window operates perfect. The drivers side window operates perfect.
The tint guys are still out there trying to fix this. There isn't some locking mechanism that could be preventing this correct? Or did they somehow short the switch out only on the passenger side switch? So aggravating.

My passenger window switch has stopped working. At first it did not want to open and close using the main switch on the driver door . (2008 1.6 3 door hatch). Then it also stopped operating on the single switch by the passenger door. Luckily its in a closed position. Is there any possible fixes, bar having to buy a new switch, as its proving hard to locate. Mostly main switches for the sedans available.

My AC is no longer running. Last summer it would struggle to get cold, but when in motion it did pretty well - just not freezing cold. Last few weeks it seemed like the compressor would switch off when stopped. Then past week, I hit the AC button (light comes on, fan switches to low, and the relay clicks) but it sounds like the AC compressor isn't engaging. The dryer is frosty to the touch, but the low and high ports in the bay are warm/hot. I checked the pressure and it was through the roof. I vented some (I know I know) out, but all that came out mostly was air with a bit of the refrigerant squirt once or twice during the vent. Still no success. Should there be air coming out of the low pressure port?

Does the oil cooler have to be removed to change out the oil pressure switch? If not, any pix or how-to posted around? Done a Google but apart for Jetta 2.0L nothing seems to come up
Believe it's located on top of the oil filter bracket according to ETKA, but that doesn't show what components are around or on top of it
Am fitting a 42DD re-location unit so I can have the switch and a GlowShift oil pressure sender onto it. Car was on a lift yesterday but couldn't see a way to get at it

The switch for turning overdrive off that's located on the auto trans shifter stopped working. I've taken off the column cover to see if the wires have been severed from the tilt wheel, but nothing wrong there. I also checked the fuses, and all is well. Is it possible that the switch is bad at the end of the shifter, or somewhere farther down the column?

I have a 2005 excursion with about 112,000 miles and last week all 5 doors decided to stop working on me when trying to lock or unlock with the remote or the door switch. I do hear a sound like something is happening just right of the fuse box. I did a little research and found that this is a wide spread problem. I did order 4 of the 5 actuators and I replaced the drivers door but nothing yet. Do they all have to be replaced in order to work? Or is it most likely something else causing this? Just trying to figure it out before I install the other actuators or take it in to a shop.

How do I jump the low pressure freon switch on a 2003 ford escape? I'm putting freon in my 2003 escape, but the compressor won't keep running, so what do I do to keep the compressor running?

Well now I have to replace the multi function switch due to moving my steering wheel and the headlights sometimes working and turning signals not working. I saw a great video on youtube about changing a Multi Function Switch and it shows where the air bag needs to be removed. I was hoping that since my truck is an older 1997 F250 LD I wouldn't have to remove the airbag. Is there a way to do this w/out messing with the airbag on the 1997?

So all but the driver door window switch stopped working including the lock and unlock buttons. The windows still go up and down but from the other door switches.
My best guess is the master switch is gone bad. And at over 65k I'm sure it's no longer under warranty. I called the local dealer today and quoted me over $500 and would not give me the part number.
After parking the car for 15mins and turned the car back on, decided to try again. Everything works now I haven't taken anything apart yet but now I'm curious what caused it to temporarily fail.
After 30 mins of the car being on I decided to roll the windows up but the switch was dead again.
