#1 of 4 Cooling Fan problems by gearhead351w Mar 11, 2009 (9:44 am)
Well I did the head gaskets and changed the crank,cam,o2, and ect sensors. The van runs great but the cooling fans are not coming on. I have waited till it almost over heats and I turn the heaters on and bring the temp down. Now I have gone thru the manuel and I know that the fans and relays are good by jumping the ground on and the fans will go into low and high speed but they will not come on by themself the guage is reading temp and I do not have any codes that pertain to the ect? I do not have a scaner that will tell me what the van temp is (cheap scaner) could the guage be off? I am begining to think I am going to have to take it to the dealer (I dont want to do that kinda of a pride thing) HELP PLEASE
#2 of 4 Fan motors inop by rdn1 Apr 07, 2009 (5:43 am)
I changed the battery in my wifes 2002 venture. Now the rad fan motors will not work. I have checked the fuse and the relays, the only time the fans will come on is if you turn on the ac or defrost and then they only work on low. Any body run in to this before?

Replying to: moakus (Aug 14, 2009 6:53 pm) my problem was as I thought the gauge was off but if you get a manual it should have the wire diagram in it remember that the computer turns on and off the ground to the fans
