i have a 93 prelude and the a/c does not work
it is full of r134a but the a/c light will not light up.
i checked all fuses and the relays and they appear to be ok.
what can i check and how does the heater a/c controls come out, the cover piece seems like it will break if i pull on it and i don't see any screws

 

Most likely the solder points need to be resoldered on the climate control harness. Here is a small write-up..
