I just checked you are right,there is no,ac relay on your car,the relay was replaced on the newer model,s with a ac Expansion Valve,if ac is full of freon and you have power at ac compressor.this valve may be your problem,it want let your freon circulate nor activate your compressor.

there is no power at the compressor. thanks

low pressure cut off switch. check to see if has juice b/f switch, you can jump lpcos momentarily and see if compressor clutch kicks on.
