I've got an '89 LX with the 2.3L. The cooling fan is not working, thereby causing the car to overheat if left to idle for extended periods such as bumper to bumper traffic.
I got the wiring digarams and I found that the absolute easiest thing to check was what alldata calls the "cooling fan temperature switch." According to the diagram this thing behaves as a simple switch, in the ground side of a relay circuit. Above a certain temperature, the switch closes and the fan comes on.
Any time the key is in the run position, If I bypass the switch directly to ground it should make the fan come on. I jumped across the switch to ground and the fan took off running like a champ. Bingo, problem solved, well problem found anyway.
I went to Advance (my first mistake I know) and they had a switch. It was an AC Delco part but of the three parts they had listed, it was the only one that even looked right. I bought the part and installed it without any trouble, well, almost no trouble. Now the fan runs any time the key is in the run position. Although this does effectively solve the overheating problem, it's highly annoying because it will likely dramatically shorten the lifespan of the fan.
Does anybody know of an aftermarket switch that will work?
The Delco part number was F1855. If I look it up at Autozone it lists a Wells TU25 which cross references to the Delco F1855. I don't really feel like the Delco unit is bad, but rather it's not the right part. I put an ohm meter on it and the resistance does go up as the car cools down, but it never gets high enough to not pick up the relay. It seems like what I have is a variable resistor when what I really need is a simple on off switch.
Is there a parts store solution or am I gonna resort to the dealership?
Thanks!
Edit - I called Ford and they would have to order the part, it is listed for $39!! The delco unit was $10. I find it really hard to believe that a technically less complicated device would cost 4 times as much. They gave me part number E7228B607A, alldata gave EOZZ8B607A, neither of these can I find any cross references to.
