Could also be the compressor relay, very common on Hondas as that's what I'm certified in but as far as the ac button light I'm not sure, could be a problem with the control panel, I know on some camrys they had problems with a wire harness, but I think it's the newer ones..
I work on hondas, I recently put a throttle body on my dads 07 Yukon 5.3 liter. I don't have a scan tool that can do it but I've heard it can be done manually, anyone know how? Any tips would help, thanks guys!!
