My 2005 accord ac has recently stopped working. I changed the compressor the compressor switch and still didn't work. I had finally just took it to Honda dealer and they said they got the compressor to engage but I will need a new pcm for 985$ for the part and labor! My question is can I buy my own pcm and install it myself? and what about reprogramming and all that. I have heard of installing a toggle switch and bypassing the computer but how long will that last?
