1995 Honda Passport A/C not blowing cold. I can hear the compressor kick on, and hear a sound like somethings trying to fill in the dash. I have added freon to to the system, but don't know if I put it in right. Any sugesstions?
Take it to a mechanic, that is nit something you "try" if you "don't know what you are doing".....doing such things usually gets you a higher bill at the mechanic, and gives him/her a reason to laugh at you....

If it has lost it's freon, it won't tell you anything about the condition of the compressor, but the compressor clutch is what goes first. With no oil, it won't come on, so, go to walmart, ( this is the cheap fix), get one of those 18 oz bottles with the oil, freon and sealer in there, hook it up to the low pressure side, give it a shot to 35 lbs, try it and see how it goes. The radiator shop will want $600 just to look. So for $19, you have nothing to lose. Check it out.
Try resetting computer and unplugging O2 sensor, and see what happens, if fine replace sensor. Ther are only so many things that can cause a rich condition, excess fuel pressure, EGR valve leaking exhaust into intake when it should be closed, no vacuum to fuel pressure regulator or ruptured fuel pressure regulator diaphram, no vaccum to MAP sensor, Air or Coolant temp senosr reading cold when engine is hot. Your mechainc shold be able to eliminate all these.
If you don't hear a click when you turn key to Start, check that the small wire onto the starter solenoid has a good connection. If you do hear the click, check that the large wire going between solenoid and battery has good connections..hope this helps.
This is very vague. Is the blower motor working (can you hear blowing inside?), is it blowing but it's hot? Can you hear the compressor running (open your hood and listen if something is kicking on and off). AC is so complex. It could be as simple as a freon leak or as complex as a compressor, hose, accumulator etc.
