Well guys, I went out and hopped in the van to go to the hardware store this morning and the SES light came on. I came home and grabbed my Actron CP913 scanner and ran the codes on it and came up with a P1491. According to my Haynes manual, this is "an open or shorted condition detected in the low speed radiator fan relay control circuit." Would the fact that I removed the 40 amp fuse and swapped the realy yesterday have tripped this code and will it reset after so many drive cycles? If not, what do y'all suggest I try next. The van runs fine, but since it's only a mile to the hardware store, I didn't get it to full operating temp to see if the light would go out. I guess I'll find out about noon when I take Mom to the doctors office.
