Hey,
Ok, the condenser is clear no crud at all and good air flow. The auxilliary fan does not come on, I will have to check that this weekend. Is that on a fuse or a relay? I think it's a relay but I don't know which one or how to test them. I did try jumping the pressure switch with no joy.
The system is still R-12 and I would like to keep it that way. I was thinking about air in the condenser but I don't know how it would get in there. The compressor should not pump into a vacuum, it should not run at all below around 30 psi. Though I do realize that it is possible.

If it was leaking freon out, it was leaking air in.

The low side hose does get condensate on it, It just doesn't cool very good unless I overcharge it. I know that's not good to do.
Actually yesterday was the first time I heard of a monovalve though I do remember reading in the Hayne's manual about a valve in the engine compartment behind the firewall.
How do you troubleshoot this valve?
Yesterday was definetely the first time I heard of a ETR valve. After searching through posts I was thinking this may be at least part of the problem.
Your right about fixing it right the first time. If I open the system up I want to do it only once. Though I do have some R-12 laying around
I was wondering if the hissing from the TEV was normal. I would assume that would mean that it is working. I was only going to replace it if I couldn't stop it from leaking.
I used a very sensitive electronic leak detector on the whole system and the only leak I found was on the TEV.
But I guess if I'm opening the system I should replace the o-rings anyway??
Oh yeah I almost forgot, It takes about 10 minutes for the pressures to equalize after shutting the AC off. It shouldn't take that long should it?
Thanks for all the feedback I appreciate it.
