Quetion about Air Conditioner

Well in closing. The high pressure condenser fan switch and the high low dual switch do not have schrader valves. I bit the bullet and had the ac shop recover the r12 and they vacuumed it down. I did not replace the dryer. I figured if I had any major issues come up with the ac I would just convert it and replace the drier then. The switches were replaced and the system was recharged and leak dye was added. Ac blows ice cold, 42 degrees cold. Its been about 3 weeks and the system still blows cold, with no bubbles or foam in the site glass and I used a black light to look for any leaks and could not find any. Keeping my fingers crossed.

I asked the ac guy about the retrofit to r134 and he said it would work ok on the 7mgte turbo model with the auto trans. Why that specific vehicle I asked. Well he explained that with the r134 you really need a large condenser. Most r12 fitted cars had small condensers. The 7mgte just happens to have the large fan / fan clutch combo and auto tranny 7ms have the extra fan in front of the condenser. Without those extras mentioned the ac would probably not blow very cold in city driving and idling.
