Hi, if i am correct, this vehicle does not have a filter for the freon in the rear a/c system. the front a/c compressor produces the pressure and suction for the rear system and there is a filter/drier called an accumulator. also there is another filter called an orifice tube. both of these items are located near the passenger firewall. the accumulator is a larger aluminum cylinder which has two hoses going to it from the compressor, and the orifice tube is located inside the high pressure discharge hose assembly near the condensor(mounted in front of the radiator). but, as far as the rear a/c goes, this vehicle uses an evaporator expansion valve for the rear a/c on most models. now, if i'm wrong, and there is actually an orifice tube in the rear, you would find it inside the hose at the very rear, near the exhaust tailpipe on the passenger side. you would have to discharge the whole system to inspect. might want to take to a shop, good luck.

How much need freeon tahoe 2001 , 4.8 engine

If you mean what is the capacity, there should be a sticker on the heater box near the firewall, or in the engine compartment with that number.
Most truck systems hold around 4 lbs or more with rear ac.

My Blower on my 2003 E500 mercedes is not working, where is the fuse loacated

I wish I could help with the exact location but most are in the fuse panel under the hood, but since you said you charged the ac, im wondering if you overcharged the the ac, because there is a high pressure sensor that will shut off the operation of your heater and ac control unit inside on the dash when you overcharge with freeon.

Just replaced the ac compressor and the ac was blowing cold air and now a month later it is not blowing cold air. 2 cans of freeon was put in. What can it be?

I do not understand why you keep reposting the same question. The answer that I provided on the 2nd post is the ONLY possible answer, unless you added 2 more cans after it stopped blowing cold - then your system is definitely overcharged. To diagnose your issue, you MUST inspect the system for a leak using a UV lamp and the correct light filter glasses. There is no way around it.

No cold air coming out of air condition just hot air

Check you ac belt under the hood is not slipping. Check that your ac clutch is engaging.
Check your freeon level.
It is possible you may have a freeon leak. The mechanics will use a dye to determine if you have a leak and where it is. The leak will be repaired and new freeon put in.

I had my ac charged with freeon in June and a month later I have no ac. I don't think this is a compressor problem. Any idea where to leak could be?

Check to see if you still have freeon. If not you have a leak. Most auto parts stores sell freeon with a stopleak and oil combination charging system.

Air conditioner will blow but not cool

You could check for a bad relay in your engine compartment, fuse box or the AC on/off switch is bad
