Picture of air intake for vw passat 1989 model

This is usually an indication of "blowback" caused by worn piston rings. How many miles on the engine? There is not a cheap solution if it is blowback.

chances are if you system was serviced by modern equipment then they would have pulled a vacuum before recharging .. that would eliminate moisture in the system .. the evaporator is inside your heater box .. you cant see it .. the condenser is the radiator like device in front of your engine cooling radiator ..

if the system is changed properly and still does not work or works intermittantly . then there is a good chance that the air conditioner clutch electronic module is bad .. thats a relay like device located on the drivers side behind the dash .. you have to snap off the dash side panel .. its normally hidden by the door .. inside that is the fuse panel and behind that is the relays/electronic modules .. the one that operates the air conditioner clutch is marked 384 .. there are other possibilities depending on your a more precise description of the problem ..

There is a bleeder valve usually located near the thermostat housing or somewhere on top of the engine. open valve until you get a flow of water. I advise not to do this when the car is at running temp or higher do this with engine cool.

Yes.... You gotta remove the air intake piece. It's plastic so it's very simple to do. Instead of a generic answer such as a website and search, here's the direct LINK where to go with the full step by step guidance on how to do this. Its a PDF document with pictures. Be prepared, though, as it's very limited space you'll be working in. Http://home.comcast.net/~slashpub/headlights/ReplacingHeadlightBulbs.pdf That link is what's mentioned here: http://www.mohea.com/mike/words/000735.html Just know that if you're ever gonna change fog lights (if your car is equipped with them) it's a whole new ball game... LoL (we had to remove the full lower bumper to get to them) Let me know if the address doesn't work and I'll guide you to another. Hope this helps.
