Hi guys,

Looking to start a discussion about the length of time it takes the A/C to start blowing cold cold cold....blah.......

From an engineering standpoint, why does the wife's '02 Explorer start blowing cold almost immediately and both of my 123's have taken some street time to start blowing cold (cold like you know you're on the right track)? It can't be the 134 vs R12 debate. The Ford runs R134....so I'm throwing it out there. And just for the record, my 123 will blow 35F on Freeze 12, just takes awhile to get there. Yeah I know the system is 25yo and the evaporator is probably dirty. What else?

i think these car's A/C systems have not been their strong point. Flame on kids:
