Message	I have a 90 TT conversion. Had the car converted over from R12 to R134 today. Put a new drier in, new O rings, flushed the system and replaced with 1.2lbs of R134 if I heard right. The mechanic had a few concerns. 1st he was is concerned because he says the pressure in the system is reaching 300psi without the fan being on. If he puts a blower on it it will drop, not sure how far. From a few messages I saw it looks like 250 - 280psi might be normal but I want to be sure. 2nd as stated he said the auxiliary fan should turn on when the AC is on but its not. From what I understand the fan shouldn't turn on until the engine temp gets around 205+. Please correct me if I am wrong. Thanks, Chris
