    hey guys, finally rooted all cooling probs. now i need my A/C working. i hate hot weather without my aircon. is there a wire i might need to plug in? if so, where is it on the 3SFE Engine bay? Stig, seeing as you have a 3SFE celica, you might be able to help...

    should be 2 switch wires near the firewall where the harness pulls through

    ok, ill look when its light. would having "no gas in system at all" cause the system to pull up a code 51? some sort of a pressure switch?

    Not sure - get it recharged and see if it the code goes away. If it doesn't, it's an electrical issue of which mafix is referring to.
