I just replaced the upper and lower rad. hoses, t-stat , ECT sensor, and rad. fan. I cleared the code PO118 and all seems well. While test driving with AC on and blowing cold, I rolled up my windows and once they were up all the way I noticed a draw on the AC. Only when I hold the button with the windows already up. …I know don't hold the button once they are up, but that's never happened before. Wondering what I may have screwed up? Looking for advice. Currently no codes. Thanks.
