1993 Honda Accord A/C Problems
My car is a 1993 Honda Accord Lx 4rd Automatic.
My accord isnt blowing cold air as easily as it used to. Ive noticed that when i am driving on the highway, the A/C will blow cold for a few seconds, then not so cold for a few seconds, then cold, and so on. When i drive on side streets, it stays cool but not as cold as it used to. Is there something that i can do to see what is wrong? It blows hard, it just doesnt get as cold as it used to. Am i able to just have it refilled? Its a 93 so im guessing that it uses freon? Am i able to have the freon refilled at a auto shop? Answers to these questions would help me out a lot. I live in Texas and i cant drive without A/C.
(I havent done any mods to my car so the A/C wasnt messed with)

I'm not sure when the A/C systems switched from R12 to R134A. Most auto shops can charge the system, but you can diagnose some simple things too.
Do both fans turn on when you turn on the A/C? When you switch on the A/C, does the compressor clutch stay engaged with the A/C pulley? It should spin at the same rate as the pulley.
I would look for any slow leaks in the system, due to age of the car. If you see dirt/dust accumulated at any connection in the A/C system, it would indicate a bad o-ring. The freon evaporates at a leak, but the oil will remain and dirt will stick to it. Recharging would be a temporary fix, because the freon would still be able to escape from the system.

The big changeover to R134a occurred in 1994, however a few car models(not sure of Hondas) made in 1993 have R134a. You can tell by looking at the fittings. The R134a fittings and caps are much larger than R12 and there should be a sticker on the radiator frame telling refrigerant type and charge volume. R12 is readily available still, if somewhat expensive. If your system is R12, I would suggest staying w/ R12 if you only need some charge.
Problem could be many things; low refrigerant charge, dirty condensor, failing expansion valve, loose or misadjusted heated air mix door, etc. You will likley have to get some professional help to resolve. Do you want to DIY?
