if i remeber correctly the evaporator for the A/C system is is the aluminum cylinder that is under the hood on the passenger side by the strut tower. if you have coolant puddling in the cabin of the car on the passenger side that would be the heater core which is midway up the firewall encased in the climate control air ducting.

I CHECKED A 96 SE FSM, BASICALLY YOU HAVE TO REMOVE EVERYTHING BLOCKING ACCESS TO FIREWALL IN VICINITY OF THE BLOWER MOTOR. INCLUDES AC ACCUMULATOR (AFTER FREON RECOVERY,ETC), ALTERNATOR, CROSS CAR BRACE, MAXI FUSE/RELAY CENTER, BLOWER CONTROL MODULE, BLOWER MOTOR, AC LINES, ACCUMULATOR BRACKET, HVAC HEAT SHIELD (MINE HAD ALREADY CRUMBLED AWAY), THEN!!!!!! CUT FIREWALL ALONG DOTTED LINES AND REMOVE HEATER AND EVAPORATOR MODULE ASSEMBLY. I LEFT OUT THE REFERENCES AS TO HOW TO REMOVE EACH ITEM BUT IT SEEMED STRAIGHT FORWARD. ALSO DON'T KNOW IF 96 FSM APPLIES TO YOUR CASE. GOOD LUCK!

oops! forgot to use lower case again. sorry adm and mods.
