Air conditioning......re-gassing query...(must get done before summer!!!!!)

[Nick Tomlinson <nickandkathryntomlinson@xxxx>]

To All, my air-con feels a bit warm at the moment so I am assuming the gas maybe a bit low. I have done the basics and checked that the belt is tight (was loose) and that there is 12v on the clutch line when the air-con is selected at the console. The clutch does engage. I haven't had chance yet to give the car a blast in case the refrigerant just needs a good spurt.
Has anyone had any problems getting R12 systems regassed? How much does it usually cost?
Has anyone had the refrigerant changed to R134a and what o-rings/ pipes had to be changed etc with what benefits cost etc...
Can someone verify if the fan switch is manually off and the air-con on, does the fan automatically cycle to blast cold air into the cabin or does the air-com stay off cycling with the pressure switch. I have the workshop manual but the working isn't that clear to me (not an electrical diagram you see !)
Thanks all in advance,
Nick. PMT250X.
ps My nokia now has a nice Delorean screen saver on my 3310 thanks to Liam.
