Update on my 1985 cavalier which the fan will not come on: Thanks Caradiodoc ! I disconnected the the wires from the coolant sensor the fan comes on. If I stick a test light in to grn/wht wire on the relay the fan comes on. The wiring is like a 1986 cavalier, it does not have a coolant fan switch as pictured on the 1985 wiring diagram. No luck on a scan tool because I have the old style connector. I presume the problem is in the low volt section, how do I trouble shoot it?
