Code 1491 STILL

[LoudRam]

Ok, I replaced the relay. I couldn't put it back in the original place because I couldn't get the old one out. So I relocated it to the side of the rad housing using a bolt in the side of the housing to mount it. I'm pretty sure that doesn't make a difference.

I let the van warm up until the temp gauge reached about 3/4 of the way up and still the fan didn't turn on. Also my OBDII scanner won't clear the code. It connects fine and even says it clearing the code but when it's done it says there is still a code there.

I triple checked the fuse and it's good.

I just thought of something... I wonder if the relay has to be mounted flat? I mounted it on the side. I know some relays it matters and some it doesn't. Does anyone know if that make a difference with this relay?

I just tried it again, this time with the relay laying flat. Everything was still the same. Maybe I need to reset the PCM? If so, how do I do that in the van? I know how to in my truck but I also know every vehicle is different.

Disconnecting the battery for a few minutes should clear the code if the problem is fixed. I think the fan won't run until the temp gage is mid or higher (or when the AC is running).
