A/C was blowing cold, then suddenly was warm, and the indicator light on the A/C button went from steady to flashing. The next day, tried again and it blew cold for 30 minutes, then again warm. Hasn't worked since. On the theory that there's a pressure switch in the sys which shuts it off if the 134 drops below a certain pressure, should I refill myself with 134 and stop-leak? I can't hear the compressor kicking in when turning on the switch and the fan.

If you mean the check engine light, if it is blinking, you should not drive the car very far because your catalytic converter will be damaged. If it is on steady or comes on once in a while, you can drive it without worry, just get the fault codes scanned at a place like Autozone and get a report of the results.
Your switch must be working since your indicator is telling you when the high beams are on, so my guess is that your bulbs are faulty. The high beam part. They probably burnt out one at a time, so you didn't notice until the second one went. Change your bulbs, and see if that solves it. If not, let me know.
You would have to measure the pressure to determine if it's pressurized correctly. The compressor won't run if it's low. What happens when you push the a/c button? Can you hear/feel the compressor kick in? It seems like in most cases it's the compressor itself or the compressor clutch that goes. It's way too common in vw's...
sounds like you have a leak in the system and have air that has entered into the system. best to have it serviced by a shop, the system will need to be inspected to find the leak and then evacuated. part replaced and refilled. leak detector will be okay
Do NOT use the cans of refrigerant with sealer in it. and do not let the shop put a sealer in it, in the long run this will cost you the replacement of the whole a/c system.
If you have all of the correct wattage bulbs installed, and they all do indeed work, I would be looking for a bad ground point on the sockets of the bulbs that are flashing rapidly. A corroded ground will cause the bulbs to flash, or "flicker" rapidly, as there is not sufficient body ground for the bulb. Clean all of the sockets if any corrosion/rust/oxidation is present.
Was what came out smoke or vapour....Sounds as if you may have been using it on auto and if so just have alook at the LED on the selction button....is it flashing out a code or is it a steady light?....It could be the expansion valve or it may be the electronic control unit....If you have a code that's showing....count the number of flashes it gives....thats the fault code number....Get that info first, so that we can go on from there....
Hi, the problem is when you are tilting the steering wheel all the way up it's putting to much tenstion on the wires that come outof your shifter that run to the tow/haul button. i am 99% sure your wires are disconected. rewire them and add some extra wire so next time there will be more slack in your wires.
