Alright I tried searching on the forum and found a little bit of stuff but no clear answer to what I'm trying to solve in particular. This all starts out with a dash swap. So I own a 1987 Honda Accord LXI hatchback 5 spd and the dash on this thing was trashed. In short I pulled an dash from a 1989 Honda Accord LX sedan auto. I had assumed that everything would be the same considering outward appearance wise they were identical. So my shop wound up doing the swap and not only did they find that the vent channels are a little different but that the climate control blend door was not working correctly. So I did some researching on the forums and found out that even though the push button controls on the 86-87 and the 88-89 are visually identical they are actually different part number. I imagine this has to do with a possible revision to the HVAC system that took place. So I went and grabbed my old push button control from the previous dash and the doors work but the control don't light up anymore! Now I'm freaked out because I'm terrified I put a whole new dash in my car and paid for it whilst simultaneously putting an incompatible harness behind it that I will now have to get the dash removed again to replace! So here's where my questions come in.
Is my diagnosis even any bit accurate as far as year range effecting the climate control and having to replace the entire harness again?
Do any of the other factors like LX vs LXI, 4 vs 3 door, or auto vs 5spd transmission effect anything?
Has anybody ever had to deal with anything like this before?
What harness will work in my car?
