2001 vw beetle ac not working. fire going to it but clutch won't kick in. where is the pressure sensors located?

Replace the retarded ignition switch,the electrical part of the switch only if possible.

the brake lights don't light up or the taillights don't light up? the brake lights are brighter than the tailights so the tailights won't show up whenbrakes are applied. if no lights work when brakes are applied then check for a bad ground at the light assembly.

Hi Steve, have the gas pressure of the AC unit checked. There are safety pressure switches in the system which will stop the operation of the AC system if the pressure is too low. regards John

without putting my machine on it and extracting the gas to see how much gas their is by weight then i couldnt even think of a reason for this sorry

• Hi, I can help.

• The fuel pump relay is 4th over on the very bottom row of the relay panel under the hood. This can be the pump too. The pump holds pressure and when the back pressure switch fails the car won't start. Or the pump could just be out period. The fuel filter can do this too.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

Check fuses and AC relay, check system pressures with AC manifold gauges to determine system charge capacity. If it is below sensor limit on freon, the comp. clutch will not kick in. I hope this helps.

Sounds like Rpm Sensor G-28. if no signal is received from the rpm sensor the engine will die. won't start until it gets a signal. test the sensor but also the wiring from the sensor.

WELL AC COMPRESSOR HAS TO BE WORKING IF YOU GETTING COLD AIR.YOU HAVE FUSE/RELAY BOX AT THE LEFT END OF THE INSTRUMENT PANEL ALSO YOU HAVE FUSE PANEL UNDER HOOD IN ENGINE COMPARTMENT ON TOP OF BATTERY.CHECK THE 30 AMP FUSES ONE CONTROL THE COOLANT FAN CONTROL MODULE IN WHICH OPERATES THE AC COMPRESSOR CLUTCH CIRCUIT AND AC PRESSURE SWITCH.

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...

Thats what it soulds like to me. The low pressure switch is what controls the clutch. Check to ensure you are topped off with refrigerant. If it is, get the low pressure switch replaced.
