Hi, I have a vw new beetle convertible 2.5 2006. The AC doesn't work. I have checked the pressure on the low side before put gas in and the gauge (the gauge of a recharche bottle) says 100 psi and it's into the red zone....
Is it too much? Is there a high pressure switch? Thanks!

Assuming the A/C does not work so the compressor does not run?

If the A/C is turned off and/or the compressor does not run, then 100 PSI on the low side is pretty normal.

See this Pressure/Temperature chart - Pressure - Temperature Chart for HFC-134a

Start by checking fuses and make sure the A/C button turns yellow when trying to use the A/C.

I have checked the fuses on top the battery and they are fine. Athena/c button turns yellow when pushed.
I'm no able to see if the clutch of the ac engages because is in a side on 2.5 liter.
Is my understanding that if the ac runs, has to run even the radiator fan. Right? I tried even that and it doesn't spin when i turn on the ac.

Check fuses in the side of the dash panel on the drivers side as well.

There may also be a relay and/or a low pressure sensor that is disconnected or bad??

I would have to look at the entire schematic to see what all the NB has for A/C controls.

Check out this site as well - Volkswagen Workshop Manuals > New Beetle L5-2.5L (BPS) (2006) > Relays and Modules > Relays and Modules - HVAC > Control Module HVAC > Component Information > Technical Service Bulletins > Customer Interest: > 8707-17 > Nov > 07 > A/C - Does Not Get

Tried all fuses and they are good.

could be the gate valve in the compressor. I have the same problem and have a trouble code for the valve. the valves are about 50 bucks, but as all things on this car they are a small pain to change.

The temperature display on the dash of the roof shows the temperature properly.
Is this the one you are talking about?

Someone has the diagram to take a look into and start testing something?

thanks!


Time to study the diagrams.

Does the outside thermometer in the car work properly?

Ambient air temp sensor problem?
