Hey guys. I swapped out my cabin air filters and right after doing it the CC unit started acting weird. The settings ?1,2,3? don?t activate the fan. The setting 4 does activate the fan. But it also shuts off the A/C unit. Very strange. I?m thinking the ECU is messed up and maybe just needs a reset. I can?t imagine I broke anything. Any help?
