[mjkrs2k]

ok start from sratch. didnt work had it gassed display stopped flashing. but still not working compressor clicking in but no cold air. ok me thinks vavle closed so today i have change the three way pressure vavle and the thermostatic control vavle re gased it still no cold air it isnt leaking as after three weeks from last gas it still got 700 gms in it. did it on the merc air con gasser at the merc garage my brother works at. only thing i can think is now there is a blockage. I was going to change the condenser driers element but how the heck do you get it out. removed the surclip but it aint wanting to come out. many thanks martin
