Hey guys i did and engine swap in my car as well and the interior harneses and under hood harnesses since the 97's werent interchangable with the other years.. short story short , i have no heat. when the engine is hot both line coming from the heater core are hot like mad so there is circulation. the heater core worked amazing before with the other harneses and other engine. this is wat happends. i turn the temperture on my climat control to hot and it blow cold air like it would be on cold. anyone have clues on this , and why im not getting hot air. you think something isent capatible with the 98 heat system and the 97 heat system. like i said , i switch the WHOLE INTERIOR harness and under hood. soo everything from the 97 gtp is in my 98 gt. only thing i dint switch is the heater core and heat system itself. thanks hopefully someone can help
 


well is it motorized. when the non supercharged engine 3800 was in that gt car it blew air no problem. and now with the other wireharness and 97 PCM gtp its like it dosent fonction properly. theres gotta be something diffferent between the two years 97 and 98 thats prob different and wont let the thermostate on the climat controls give heat. i dont know much about these systems and that is why im asking. thanks
