Have a 1996 Vento (Jetta) that seems to have a flood on the passenger side. Mould and all. I am guessing it could be an air conditioner leak... 1. Where would be the best place to start to find the leak? 2. How hard is it to remove all the carpet? Thanks!

Question edited for clarity.
Question moved to model category.

1992 to 1999 are all the same

Probably a build up of grime, mould, cigarette smoke(if you smoke in the car)_ etc etc. The air intake is under the passenger side. On some models , there is a filter that can be removed and cleaned, you would have to check with your Owners manual or a Dealer. There are cans of air con deodorisers available from Air conditioner parts stores (Actrol, Heatcraft , Airfridge etc) Spray the can into the air inlet of the air con whilst running. It kills anything bad and cleans and sterilises the air con. These cans are about $45 to $50 each, but they work better than unloading a can of Glen 20.

Use a long Zip or Wire tie to run up it...

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..

This is either two things. 1: The air conditioner condenser is leaking and will have to be siliconed, or you have a bead door or other weather stip that is allowing water in.

It is most likely leaking from the windshield and running down to the floor. Good luck and dont forget to rate

somewhere there is a air leak on the suction side of the pump.  Try tightening the clamps and connections.

Th cowling let in fresh air for the heateer and defroster, Their is a drain in the bottom of the cowling or heater ductwork which allows the water to escape before going into the car. I woudl gues that the drain is stopped up..

most likely the valve body or the TCM

The a/c drain tube will be located on the firewall. It will be on the passenger side twards the bottom of the firewall. It will be about 3/8 inch in diameter, and about 1-2 inches long sticking out of the firewall. You will probably need to get under the vehicle to gain acess.
