2002 Caravan cooling fans not running?
I have an 02 Carivan with a 3.8L. The check engine light came on. When I checked it, it was code 1491 (cooling fan relay). I replaced the relay. It worked for a few days, then the light came back on. I plugged the old relay back in. It worked. I plugged the new relay in. It worked for a few days, again. I jumped the fans. They both work fine. While messing with the relays, I noticed that one of the wires (red w/purple, about 1/8" diameter) would get very hot. The other three stayed normal temp. I also noticed that when the fans quit working, the A/C would not blow cold. The compressor seems to kick on and off normally. When the fans work, the A/C blows cold. I have moved some of the relays in the relay box around to make sure they all were good. I did the same with the fuses. Thank you to anyone that may have helpful information.
