My sister has a 2018 Equinox (1.5L turbocharged 4-cylinder (LYX)) that has ok cold a/c when driving, but it gets warmer when idling at a stoplight (like warmer than it used to be). If you start the car with the ac off, the radiator fan doesn't spin. If you turn the ac to max, the fan moves about 1/2 a blade width, pauses, then starts spinning, but there's a noise i take to be grinding. I believe this is a bad fan and was going to order the assembly, but I thought I'd ask other opinions before taking that step. Any feedback appreciated!
