A/C just not cold enough.
1987 convertible (converted a/c)
Replaced compressor, drier, hoses.. no leaks that i can tell
just doesnt seem to blow cold enough, any ideas what i can try? or is that "just the way it is"
it is exceptionally hot outside, south florida, but it should blow colder...
what are your c4's AC like?

My 85 (converted to 134a) has mid 50 degrees coming out the vents even when outside temps are mid to high 90s. If temps get down to low 90s I'll have 40 degrees coming out the vents. I'm in East Texas and hot and humid is normal for much of the year. Your AC should work fine if everything is in working order.

Did you pull a vacumm on the system prior to recharge to remove moisture, and did you replace the amount of oil that was removed from the replaced componenets ? Is your system orig. R12 or R134A convert ?

You mentioned "converted" in your first post, does that mean you are using 134a instead of R12? I'm not an expert, but I suspect you may have to go back to R12 if you want temps colder than what I am getting.

Assuming the Temp Door is completely closed and everything is clean, too little or too much gas. Get your operating pressures at 1200 rpms, fan switch disconnected so the main fan is running, and post them along with the temp of the air at the Condensor. Hint: R134 is 32 Degrees at 28 psi (R12 is 32 at 30 psi). If you have that at the Low Pressure fitting on the Accumulator, it's actually a little warmer because it's absorbed latent heat after it's boiled, but that's a good target for the Low Side at 70 degrees. With 90 and up ambients, it's going to be higher, but if your cracking the 50's or 60's on the low side, it isn't going to make cool air - let some gas out.

One thing I can suggest that did seem to help a little for me is that you are get a variable adjusting orifice tube. If you are replacing the tube anyway. But if you don't have it apart for another reason I would just use the stocker. Don't have a link handy for it, sorry.

Dunno if it will help but you might try installing a gate valve in the hot supply for the heater core and shutting it off for the summer. The OEM valve may not be halting the flow of hot water and may be causing some problem.
