Copper vs. aluminum condenser?
Someone mentioned in this thread changing out the condenser (not evaporator) to a copper one vs. the aluminum one.
Does this help with the lower cooling efficiency of R134a vs. R12?
I'm asking, because my 1988 300TE wagon was converted to R134a, but it doesn't blow as cold as my 1993 500E which has a different condenser and two aux. fans vs. the 1988's single aux. fan.
