I bought 02 Dodge Ram 1500 5.9 code 1491 keeps coming back fuse 39 not blown I’ve replaced relay and removed code. As soon as I turn ac on it triggers the check engine light back on. The ac fan will only kick on if I remove fuse 39 and put it back in but the ac has to running when I do so. The minute I shut the truck off I have to repeat the process to get the fan to blow. I’ve tried to reset the code and not run the ac to reset the drive cycle but light came back on twice at around 80-85 miles into it. Any ideas what I could do next. Any help would be appreciated thanks
