I have just bought a 206 xsi/53 reg and not sure how to determine whether the air con system just needs re-gassing or something else more expensive.
Also the heater doesn't blow, hot or cold air, do I need to replace the whole heater matrix and fan?
Your advice is much appreciated as a newbie member

If you switch the aircon on with engine running then you should hear quite a loud "clack" as the compressor clutch engages. Don't hear any "clack"? Then the aircon compressor clutch isn't engaging, most probable cause, lack of pressure in the system. You can check pressure by connecting up proper aircon pressure gauge or get a garage or other outlet to do it for you
Heater fan not working? You need to trace the electrics as to why, first step would be checking fuse then check if you have power and earth supplied at the fan

If the cabin fan blower isn't coming-on the clutch will not engage anyway.
Could well be blower motor control switch by the sound of it and will likely need re-gasing as well.

im having the same issue with my air con, the clutch is engaging, there is gas in the system but upon listening to the compressor it is turning on and off, is the compressor faulty?

Not really the same issue as your compressor is working, ie the clutch is engaging and it's normal for the compressor to cycle on/off once the system is down to the right temperature. If it's cycling rapidly eg every few seconds constantly then a cause can be the system being overpressurised

I don't think so on a 206.

Ha! Its the same for all air con systems and the 206 is no different. In cooler climates where the aircon has an easier job to keep cabin temps down then it will turn off the compressor when the system has lowered the temperature enough. In hot conditions the A/C will be working hard and not have much chance to take a break
recharge a/c <<click here
17min onwards you will see compressor cycling

With respect, it most certainly is not.
The 206 does not cycle the engaging clutch of the A/C compressor.
It would affect driving quality and all you have to do is press the button whilist driving to feel the 'jolt'.
The video is some other vehicle in the US, and they don't all work the same. He also didn't add specific type and amount of compressor oil in there and overall I would classify that whole process as a bodge (see YT comments for the video).
Regards the issue of James, in all likelyhood the amount of gas present in the system is borderline, so momentarily droping below acceptable pressure threshold and in effect 'motorboating' [ en.wikipedia.org/wiki/...ectronics) ].

hmm, think im gna get it checked, definately not getting any aircon, if i am right if you turn in a/c at the lowest setting its ice cold well mines offers no change, i'll let use know what it is when i get it checked

Well mine has always continuously clicked on and off, and is working correctly. Nice and cold.

Yes, that's a correctly working A/C. But then you already knew that
If an A/C is short cycling ie turning on/off too rapidly then that's not right but it's perfectly normal for the compressor to only be turned on when it's needed and turned off when it's not

You are right,
The switch panel type like this: 
Does indeed cycle the compressor depending on cabin temp, setting etc. Never seen it over here, I believe they call it 'climate control' type.
The other spec panel: 
Does not cycle the clutch but comes-on as soon as you press the A/C button, as long as the blower fan setting is above OFF, and the temp setting on the right is on full cold.
I appologise.

No problem, it's difficult to generalise over many different systems but all A/C s are basically the same, it's just some have more refinements than others

There is no clack sound from the air con. So next I took out the blower motor and tested it with a spare battery and speaker wire, works fine. All the fuses are ok and there is a live on the lead that connects to the blower motor. Is it the the resistor inside the fan housing that is faulty?
Also my radio won't power on. Have tried disconnecting the clock/battery and reconnecting and still doesn't want to turn on. Any ideas?

Do you have one of the switch panels shown in above pics?
There is also a heater motor blower resistor mounted on the top side of one of the vents.
That has a thermal non-resetable fuse incorporated on it and might be worth checking that too.
If other stuff doesn't work on the car, it might be something else that needs pin-pointing which is related though.
