Question about Volkswagen Beetle

Open Question

Hello, Replaced the A/C compressor, expansion valve and dryer. Flushed entire system, vacuumed the air out and filled with oil and 45 bmi of refrigerant. Car blows cold when driving, but warms up at idle or stop. I hit the accelerator to bring up the RPM for a min, then the fan kicked on and started blowing cold again. What do you think I should look into? Im thinking some kind of sensor that turns the fan on to send air to the condenser. Oh it is a 2002 VW Beetle. Thank you, Jesse

SOURCE: 2000 VW Beetle 2.0L the air conditioner was

at idle most a/c get warmer as they are not under load to circulate the freon at a rapid pace
changing the dryer is wasting your money won't change anything sounds to me as if there might be a vapour lock in the system. run the car for a week with a/c on max to fully circulate freon to see if the problem goes away if not go back to the shot tell them to check system with gauges on the high and low side to make sure that it infact is properly charged with the right amount and temp.
42-54 degrees is good

SOURCE: Ac is not blowing like it should

This sounds like an issue with the blend doors or the A/C control head. Check out the blend door motor to see if it is properly shutting the doors off to the engine compartment. The reason the passenger side is cooler is because it is located next to the evaporator, so the cool air has a shorter distance to travel into the car. The A/C control head is a big problem with RX-8's. Hope this helps.

2008. Why isn't the air conditioning working better?

When the compressor is replaced it should have had at least 2oz of oil inserted into it. The entire system should have been flushed to remove any foreign debris ( especially if the original compressor/clutch failed ). The system then needs to be vacuumed down to remove any moisture for a minimum of ten minutes and then leak tested to ensure vacuum holds. The system is then filled with the proper charge of freon and oil and then monitored for guage pressures and signs of leaks to ensure proper operation and effective cooling

91honda prelude ac pressures good, no cooling

Sounds like low charge or poss defective AC compressor or the expansive valve has moisture in it. Did you pull a vacuum on the system for 45 minutes before adding refrigerant?

I am looking to convert the AC over to 134a. I have heard that the oil, the dryer and the expansive valve need to be replaced and then the system vacuumed out. where are the expansion valve and the dryer...

Look for the expansion valve where two of the AC lines connect together, usually near the radiator and the lines may be slightly different diameters, the larger one contains the valve. It is also VERY important to flush ALL of the old oil out of the system. Do this with an AC flush kit and all parts removed. Concentrate on the condensor and the evaporator after the hoses are flushed. Coat all 'o"rings and seals with AC oil when reassembling and be careful, leaks can happen and will be costly. Install 1/3 of system oil capacity in compressor and TURN the compressor by HAND after hoses are installed to it. OIL DOES NOT COMPRESS!! You may want to have a shop evacuate the system when ready.

2003 Malibu repeated Air conditioner failure

None of the repairs work , If the system is not entirely flushed out, dryers, expansion valves and the like are replaced. If the original problem involved compressor failure, tiny bits of medal and debris may be still circulating in the system and casing other components in that system to fail. Someone does not know what they are doing.

Did you replace the 'expansion valve'. If the expansion valve is full of **** no coolant will get through to cool.
