Air conditioner is running back ward on 2003 volkwagon jetta - hsbr 3004 Volkdesgrn Jetts with rebuilt 1999 Air Conditioner compressor recently installed. The fan is running counter clock wise instead of clockwise causing pressure to build up.
Re: Air conditioner is running back ward on 2003...
The fan maybe running the right way, it should be sucking air in through the condensor, check out first. If so maybe moisture in system would require evacuating

Probably, to be sure make sure the compressor is coming on. With the engine running turn on the ac and watch the rpms, they should drop for a second if the compressor is coming on. If so you just need to recharge, the refrigerant is R-134a, which you can get from your local parts store along with the kit needed to charge it. The kit will come with detailed instructions and is a pretty easy job.
The anti coolant is what is added to your radiator so that the water does not freeze when the temp goes down and damage your pump. hence do not confuse this with the air conditioner. When you put on the a/c the load noise could be the engagement of the solenoid coupling your a/c compressor to the engine. If you notice within the bonnet for the gas filling inlet there must be signs of cooling. if not check over the condenser filter on the glass window for any signs of gas or gas pressure , smoky means low gas but a good pressure of gas indicates good visiblity. If not there has been a gas leak and your whole a/c system needs a check right from the compressor to the condenser to the cooling coils inside the dash. The leak has to identified by a pressure check with air filled, check for blocks before the gas can be filled. The compressor pump pressure must be checked or must be overhauled, replacement of the O rings, and reset. I hope you got an idea to proceed and hope I could help. Good day.
I presume the compressor you refer to is the air conditioner compressor.
If so, the car can be usually be driven as normal so long as you don't operate the air conditioner cooling. With the air conditioner off, the compressor is not in use.
If the fault with the a/c compressor is with the front bearing (drive noise or belt squeal) you may need to remove the drive belt.
You may not be full of refrigerant... There is a low pressure switch that prevents the AC from actuating the clutch, and the reason is: IF there is not enough refrigerant, you will not be able to move oil through the system and you will have major damage...so no engauge...
Get the system checked, most likely there is a leak somewhere..
check air conditioner compressor fuse or relay.if all is good.you have a open compressor clutch coil or a bad compressor.also check compressor clutch wire.
you should take it to the garage and to ask them to check if your air
point(in the engine) connected properly-in most cases that appear to be
the problem
